A disease that spreads from person to another by contact is said to be contagious. This means that the disease can be transmitted through direct or indirect contact with an infected individual, such as through physical touch, respiratory droplets, or contaminated surfaces. Contagious diseases are easily spread within a community or population, making it important to take preventive measures, such as practicing good hygiene and social distancing, to limit their transmission.

When body tissues are invaded by disease-causing or pathogenic bacteria, it leads to an infection. An infection occurs when harmful bacteria enter the body and start multiplying, causing damage to the tissues and triggering an immune response. This immune response can result in symptoms such as inflammation, fever, and pain. Therefore, infection is the correct answer as it accurately describes the consequence of bacteria invading body tissues.

In a client consultation, a practitioner engages in a conversation with a client to offer professional advice and suggestions. This interaction is focused on understanding the client's needs, discussing their concerns, and providing appropriate recommendations or solutions. It is a formal and structured session where the practitioner utilizes their expertise to guide the client towards achieving their goals or addressing their issues.

The correct temperature setting of the iron for thermal curling is determined by the texture of the hair. Different hair textures require different levels of heat to achieve the desired curl. Fine or damaged hair may require a lower temperature setting to prevent further damage, while coarse or thick hair may need a higher temperature to effectively curl. The length of the hair, type of iron used, and size of iron used can also influence the temperature setting, but the texture of the hair is the primary factor to consider.

Exothermic waves refer to a type of chemical reaction that releases heat. When these waves occur, they cause the solution to heat up. This increase in temperature can have the effect of speeding up the processing of the solution. Therefore, the correct answer is processing, as exothermic waves create a chemical reaction that heats the solution and speeds up its processing.

Scabies is a contagious skin disease caused by the itch mite. It is characterized by intense itching and a rash that is usually found on the hands, wrists, and between the fingers. The mite burrows into the skin, laying eggs and causing an allergic reaction. Scabies is easily spread through close physical contact, such as sexual activity or sharing bedding or clothing. Treatment usually involves prescription creams or lotions that kill the mites and their eggs.

The area of the head that is between the apex and the back of the parietal ridge is referred to as the crown. This area is located at the top of the head, and it is where the hair tends to naturally separate and fall in different directions. The crown is an important area to consider when styling hair, as it can greatly impact the overall look and shape of a hairstyle.

A "travelling guide" refers to a guideline that moves from one position to another in a sequential manner. In this context, the guideline mentioned in the question is described as a small slice of a previous subsection that is moved to the next position and becomes the new guideline. Hence, the term "travelling guide" accurately represents this process of the guideline moving from one position to another.

Blow-dry styling is the technique of drying and styling damp hair simultaneously using a blow dryer and various tools such as brushes, combs, and styling products. This method helps to achieve the desired hairstyle quickly and efficiently by using heat to evaporate moisture from the hair while shaping it. It is a popular technique in salons and allows for versatility in creating different hairstyles.

The three main layers of the hair shaft are the cuticle, cortex, and medulla layer. The cuticle is the outermost layer that protects the hair, while the cortex is the middle layer responsible for the hair's strength, elasticity, and color. The medulla layer is the innermost layer, found in some hairs, and it consists of soft cells that may or may not be present in all hair types. The medulla layer helps to provide additional support and structure to the hair shaft.

Direct current refers to the flow of electric charge in one direction only. Unlike alternating current, which periodically reverses direction, direct current maintains a constant flow of electrons. This type of current is commonly used in batteries, solar panels, and electronic devices that require a steady and continuous flow of electricity.

Hair texture refers to the overall look and feel of the hair, which is determined by various factors. One of the main factors that determine hair texture is the diameter of individual hair strands. The thickness or thinness of each strand contributes to the overall texture of the hair. Hair strands can be thick or thin, and this characteristic affects how the hair appears and behaves. Therefore, the correct answer is "strands" as it accurately explains the role of hair diameter in determining hair texture.

Archeological studies have provided evidence that haircutting and hairstyling were practiced in some form during the ice age. This suggests that early humans recognized the importance of grooming and personal appearance even in such early stages of civilization. The discovery of tools and artifacts related to hair care in ice age sites supports this finding. Therefore, it can be concluded that the practice of haircutting and hairstyling dates back to the ice age.

For a client with a round facial type, the ideal styling choice would be to have volume on top to create height and elongate the face. This helps to balance out the roundness of the face. Additionally, having closeness or no volume at the sides helps to create the illusion of a slimmer face by minimizing width. This combination of volume on top and closeness or no volume at the sides creates a flattering and balanced look for someone with a round facial type.

Ethyl alcohol is a common volatile organic compound that evaporates quickly and is commonly used in hair spray. It helps to disperse the other ingredients in the hair spray and allows it to dry quickly on the hair. Ethyl alcohol is a solvent that helps to dissolve the resins and polymers in the hair spray, allowing it to be sprayed evenly and create a strong hold. Due to its volatility, it evaporates quickly after application, leaving the hair with the desired style and hold.

To reduce strain on the index finger and thumb while cutting hair, it is important to palm the shears. Palming the shears means holding them in the palm of the hand, with the thumb and index finger lightly gripping the handles. This technique helps distribute the pressure and workload across the entire hand, reducing strain on the fingers. It also allows for better control and precision while cutting.

Point cutting is a texturizing technique where the tips of the shears are used to remove bulk from the ends of the hair. This technique helps to create a softer and more blended look by adding movement and texture to the hair. It involves making small, strategic cuts into the hair, rather than cutting straight across. Point cutting is commonly used to add texture to layered haircuts and to remove weight from thick or heavy hair.

During a retouch relaxer application, it is important not to overlap the relaxer. Overlapping the relaxer means applying it to previously relaxed hair, which can lead to overprocessing and hair breakage. Overprocessing occurs when the relaxer is left on the hair for too long or applied to already processed hair, causing the hair to become weak and prone to breakage. To avoid this, it is important to only apply the relaxer to new growth and not to areas that have already been relaxed.

A finger wave style is an example of a design that uses curved, parallel lines to create interest. This style involves shaping the hair into "S" or "C" waves using a comb and fingers, resulting in a visually appealing and textured look. The curved lines in the finger wave style add movement and dimension to the design, making it an interesting and unique choice.

A cap wig is the recommended type for a client with no hair or extremely thin hair. This type of wig is designed with a cap that covers the entire head, providing full coverage and a natural look. The cap is typically made of a lightweight and breathable material, allowing the scalp to breathe and preventing any discomfort. The cap wig also offers the option to add hair extensions or additional hairpieces for added volume and customization.

Hepatitis is a disease caused by a bloodborne virus and is characterized by inflammation of the liver. It can be caused by different types of viruses, such as hepatitis A, B, C, D, and E. The inflammation of the liver can lead to various symptoms, including fatigue, jaundice, abdominal pain, and liver damage. Hepatitis can be transmitted through contact with infected blood or bodily fluids, contaminated food or water, or through sexual contact. Treatment options for hepatitis vary depending on the type and severity of the infection.

Fine hair takes color faster and can look darker because the melanin granules are grouped more tightly. When the melanin granules are closely packed together, they absorb more color pigment, resulting in a darker appearance. Fine hair, which has a smaller diameter, has a higher density of melanin granules per unit area compared to thicker hair. This denser grouping of melanin granules in fine hair allows for faster and more efficient absorption of color, leading to a darker appearance.

Cocci are round-shaped pathogenic bacteria that can appear singly or in groups. They are characterized by their spherical shape and can be found in various arrangements, such as pairs (diplococci), chains (streptococci), or clusters (staphylococci). Bacilli, on the other hand, are rod-shaped bacteria, spirilla are spiral-shaped bacteria, and Lyme disease is a specific bacterial infection caused by the spirochete bacteria Borrelia burgdorferi. Therefore, the correct answer is cocci.

Ethyl alcohol is commonly used as a disinfectant or antiseptic. In order for it to be effective in killing bacteria and viruses, it needs to have a high enough concentration. A strength of 70 percent or higher is recommended because it allows for the optimal balance of water and alcohol. This concentration helps to disrupt the cell membranes of microorganisms, leading to their destruction. Lower concentrations may not be as effective in killing pathogens, making 70 percent the minimum strength required for ethyl alcohol to be effective.

The hair shaft is the correct answer because it refers to the part of the hair that is visible above the skin's surface. It is composed of dead cells that have been pushed up through the hair follicle. The hair shaft is responsible for giving hair its length and texture, and it can be styled and manipulated.

When the cuticle of the hair is lifted and the hair is overly porous and absorbs color quickly, it indicates that the hair porosity is high. High porosity means that the hair has gaps and holes in the cuticle, allowing moisture and chemicals to easily enter and exit the hair shaft. This can make the hair prone to damage, frizz, and color fading.

Quaternary ammonium compounds, commonly known as quats, are a very safe and useful type of disinfectant. They are commonly used as antiseptics and disinfectants in various settings, including hospitals, households, and industries. Quats have strong antimicrobial properties and are effective against a wide range of bacteria, viruses, and fungi. They are also known for their ability to sanitize and deodorize surfaces. Due to their safety profile and effectiveness, quaternary ammonium compounds are widely used in the healthcare and cleaning industries.

Alopecia areata refers to the sudden falling out of hair in round patches or baldness in spots. It is an autoimmune condition where the immune system mistakenly attacks the hair follicles, causing hair loss. This condition can occur at any age and can affect both men and women. It is not related to postpartum alopecia, which is hair loss that occurs after giving birth, or alopecia androgenetica, which is male or female pattern baldness. Alopecia totalis refers to complete loss of scalp hair, whereas alopecia areata is characterized by patchy hair loss.

Sections are the uniform working areas used for control during haircutting. They help to maintain consistency and precision in the haircut by dividing the hair into manageable parts. Each section is typically created by parting the hair in a specific direction or pattern, allowing the stylist to work on one section at a time. This ensures that the haircut is evenly distributed and balanced throughout the head.

Barrel curls are large diameter pin curls that are similar to a roller but do not have the same amount of tension. They create a looser, more relaxed curl compared to other types of curls. This type of curl is often used to add volume and texture to the hair.

An element is the simplest form of matter that cannot be broken down without the loss of identity. Elements are made up of atoms, which are the basic building blocks of matter. Each element has a unique set of properties and characteristics that distinguish it from other elements. Unlike substances or minerals, which can be composed of multiple elements or compounds, an element is pure and consists of only one type of atom. Energy, on the other hand, is not a form of matter but a property or ability to do work.

The correct answer is "telsa current". However, there is no information provided in the question about what telsa current refers to. Therefore, it is not possible to provide an accurate explanation for this answer.

The hair shaft that emerges from the scalp is composed of keratinized protein. Keratin is a tough, fibrous protein that forms the structure of hair, nails, and the outer layer of the skin. Keratinization is the process by which cells in the hair follicle are converted into keratin, resulting in the formation of the hair shaft. This process involves the hardening and strengthening of the cells through the cross-linking of keratin proteins. Therefore, the hair shaft is a nonliving fiber made up of keratinized protein.

Nonstripping refers to products that do not remove or strip away artificial color from the hair. This means that these products are gentle and do not cause the color to fade or wash out. Therefore, if a product does not remove artificial color, it can be categorized as nonstripping.

Sodium chloride is commonly known as table salt. It is a chemical compound that is widely used as a seasoning and preservative in food. It is not a shampoo, sugar, or distilled water.

A complete circuit refers to a closed pathway that allows the flow of electric current from the generating source back to the original source without any interruptions or breaks. In a complete circuit, there are no open switches or disconnected wires, ensuring that the current can continuously flow through the circuit. This enables the electrical devices or components connected to the circuit to function properly, as the flow of electrons is uninterrupted.

A single line of color or a series of repeated lines can create a bold and dramatic accent. This is because the use of a single line or repeated lines draws attention and creates a strong visual impact. The boldness and drama come from the contrast and emphasis that the line(s) provide, adding intensity and excitement to the overall composition.

The correct answer is "belly." In muscle anatomy, the belly refers to the central, fleshy part of the muscle. It is the thickest and most contractile portion of the muscle, responsible for generating force and movement. The belly is located between the muscle's origin (the point where it attaches to a stationary bone) and its insertion (the point where it attaches to a movable bone).

The thumb is the correct answer because it has the slowest nail growth rate compared to the other fingers. This is because the thumb nail receives less blood flow and nutrients compared to the other fingers, resulting in slower growth.

Achieving balance within a design can be accomplished by understanding the head shape and reference points. Reference points are specific points on the head that help in creating a balanced and visually appealing design. These points act as a guide for the placement of elements in the design, ensuring that they are evenly distributed and harmonious. By considering the head shape and utilizing reference points, designers can achieve a sense of balance and proportion in their designs.

White light is the correct answer because it refers to a combination of all the visible rays of the spectrum. When white light passes through a prism, it splits into different colors, showing that it consists of all the colors of the rainbow. White light is what we perceive when all the colors are present in equal amounts, and it is commonly seen in sunlight and light bulbs.

The correct answer is parietal ridge. The parietal ridge is the part of the head that can be located by placing a comb flat on the side of the head. It is a reference point that helps in determining the placement and direction of various hairstyles and haircuts. The parietal ridge is an important landmark in hairdressing and styling as it helps create balance and symmetry in the overall look.

The terms single braids, box braids, or individual braids all refer to free-hanging braids. These types of braids are created by sectioning the hair into small parts and braiding each section individually. The braids are not attached or connected to each other, allowing them to hang freely. This style is popular for its versatility and ability to be customized with various lengths, sizes, and patterns.

Volume refers to the amount of space that a hairstyle occupies. It is a measure of how full and three-dimensional the hairstyle appears. The term "volume" is commonly used in the context of hair to describe the thickness, fullness, and overall size of the hairstyle. A hairstyle with high volume will appear larger and more voluminous, while a hairstyle with low volume will appear flatter and less full. Therefore, volume is an appropriate term to describe the form or mass of a hairstyle.

Contrasting lines are created by the intersection of horizontal and vertical lines, which results in a sharp and distinct edge. This intersection forms a 90-degree angle, as both horizontal and vertical lines are perpendicular to each other.

Protein and biotin are two conditioning agents that boost shampoos and restore moisture and elasticity to the hair shaft. Protein helps to strengthen the hair and repair damage, while biotin promotes hair growth and improves the overall health of the hair. These two ingredients work together to nourish and rejuvenate the hair, leaving it soft, smooth, and manageable.

A triangular base is recommended to use along the front hairline to prevent splits or breaks in the finished style. This base shape provides stability and support to the hair, ensuring that it stays in place and doesn't split or break during styling. The triangular shape allows for even distribution of tension and weight, reducing the risk of damage to the hair. Using a triangular base helps create a strong foundation for the style, resulting in a more polished and long-lasting look.

Good-quality pressing combs are typically made of stainless steel or brass. These materials are chosen for their durability and heat conductivity. Stainless steel is resistant to rust and corrosion, making it a suitable option for a long-lasting pressing comb. Brass is also a popular choice due to its ability to distribute heat evenly and effectively. Both stainless steel and brass combs are known for their high-quality performance in straightening and styling hair.

Physiology is the study of the functions and activities performed by the body structures. It focuses on how different organs and systems work together to maintain homeostasis and carry out various bodily functions. This field of study helps in understanding the mechanisms behind processes such as digestion, respiration, circulation, and reproduction. By studying physiology, researchers and healthcare professionals gain insights into the normal functioning of the human body and can better understand and treat diseases and disorders.

Striated muscles are the correct answer because they are attached to bones and are voluntary or controlled by the will. These muscles are also known as skeletal muscles and are responsible for our voluntary movements, such as walking, running, and lifting weights. They have a striped or striated appearance under a microscope due to the arrangement of their contractile proteins.
