Bacteria are not harmed by disinfectants while in the
Correct Answer
B. Spore-forming stage
Explanation
Bacteria are not harmed by disinfectants while in the spore-forming stage because spores have a tough outer coat that protects them from the effects of disinfectants. Spores are dormant and metabolically inactive, allowing them to survive in harsh conditions. Disinfectants are designed to target and kill actively growing bacteria, which are in the vegetative or active stage. During mitosis, bacteria are actively dividing and are also susceptible to the effects of disinfectants. Therefore, it is the spore-forming stage where bacteria are most resistant to disinfectants.
5.
Bacilli are bacteria with a
Correct Answer
C. Rod shape
Explanation
Bacilli are bacteria that have a rod shape. This means that they are elongated and cylindrical in structure, resembling a small rod or stick. This shape allows them to move efficiently through various environments and helps them in their functions such as reproduction and nutrient uptake. Unlike other shapes like corkscrew, round, or curved, bacilli have a distinct elongated appearance.
6.
Acquired immune deficiency syndrome (aids)
Correct Answer
D. Is caused by HIV virus
Explanation
Acquired immune deficiency syndrome (AIDS) is caused by the HIV virus. HIV (human immunodeficiency virus) attacks the immune system, specifically the CD4 cells (T cells), which are crucial for fighting off infections. Over time, HIV can destroy so many of these cells that the body becomes unable to fight off infections and diseases, leading to the development of AIDS. AIDS is the final stage of HIV infection, characterized by a severely weakened immune system and the presence of opportunistic infections and certain cancers.
7.
Surfaces that may be sterilized are:
Correct Answer
B. Nonporous
Explanation
Nonporous surfaces can be sterilized because they do not have any tiny pores or openings that can harbor bacteria or other microorganisms. Unlike porous surfaces like skin, nail plates, wood, or plastic, nonporous surfaces can be easily cleaned and disinfected using various sterilization methods such as heat, chemicals, or radiation. This ensures that all microorganisms present on the surface are killed, making it safe and free from contamination.
8.
Disinfection is one step below sterilization because it does not
Correct Answer
B. Kill bacterial spores
Explanation
Disinfection is one step below sterilization because it does not kill bacterial spores. Disinfection is the process of reducing the number of microorganisms to a level that is considered safe for public health. While it can effectively kill most bacteria and viruses, it may not be able to eliminate bacterial spores, which are highly resistant structures that can survive in harsh conditions. Sterilization, on the other hand, is a process that completely eliminates all forms of microbial life, including bacterial spores. Therefore, disinfection is not as effective as sterilization in eliminating bacterial spores.

The technical term for eyelash hair is
Correct Answer
B. Cilia
Explanation
The technical term for eyelash hair is "cilia". Cilia are the short, thin, and curved hairs that grow on the edges of the eyelids. They serve the purpose of protecting the eyes from foreign particles, such as dust, by trapping them and preventing them from entering the eye.
10.
The chemical composition of hair varies with its
Correct Answer
A. Color
Explanation
The chemical composition of hair varies with its color because the pigments responsible for hair color are produced by specialized cells called melanocytes. These melanocytes produce two types of pigment: eumelanin, which gives hair a brown or black color, and pheomelanin, which gives hair a red or blonde color. The amount and distribution of these pigments determine the overall color of the hair. Therefore, different hair colors have different chemical compositions based on the type and amount of pigments present.
11.
The club-shaped structure that forms the lower part of the hair root is the
Correct Answer
B. Bulb
Explanation
The bulb is the correct answer because it is the club-shaped structure that forms the lower part of the hair root. It is located at the base of the hair follicle and contains the actively dividing cells that produce the hair shaft. The bulb is responsible for the growth and nourishment of the hair, as well as anchoring it in the scalp. The arrector pili, papilla, and hair shaft are all associated with the hair, but they do not specifically form the lower part of the hair root like the bulb does.
12.
The growing phase of hair is known as
Correct Answer
A. Anagen
Explanation
The correct answer is anagen. Anagen is the active phase of hair growth, during which the hair follicle produces new cells that form the hair shaft. This phase can last for several years and determines the length of the hair. Mitosis is the process of cell division and is not specific to hair growth phases. Catagen is the transitional phase between anagen and telogen, where hair growth stops. Telogen is the resting phase, during which the hair follicle is inactive and eventually sheds the hair.
13.
A topical solution applied to the scalp that is medically proven to regrow hair is
Correct Answer
C. Monoxidil
Explanation
Monoxidil is a topical solution that is medically proven to regrow hair. It is commonly used for the treatment of male pattern baldness and works by increasing blood flow to the hair follicles, stimulating hair growth. Finasteride is an oral medication used for hair loss, not a topical solution. Astringent and hot oil are not known to be medically proven solutions for hair regrowth.
14.
Long, thick pigmented hair is known as
Correct Answer
B. Terminal
Explanation
Terminal hair refers to the long, thick pigmented hair that grows on various parts of the body such as the scalp, eyebrows, and armpits. It is different from vellus hair, which is shorter, finer, and less pigmented. Terminal hair is typically found in adults and is influenced by hormones. It serves various functions such as providing insulation, protection, and sensory perception.
15.
Hair flowing in the same direction is known as:
Correct Answer
B. The hair stream
Explanation
The term "hair stream" refers to the direction in which the hair naturally flows or grows. It describes the pattern or direction in which the hair strands align. This can vary from person to person, and it is influenced by factors such as genetics and hair care practices. The hair stream is different from other terms listed in the question, such as "the natural parting," which refers to the division of hair into sections, "a cowlick," which is a section of hair that stands upright or grows in a different direction, and "the hairline," which is the outline of hair growth along the forehead.
16.
A miniaturization of certain scalp follicles contributes to:
Correct Answer
A. Androgenetic alopecia
Explanation
Androgenetic alopecia is a condition characterized by the miniaturization of scalp follicles. This means that the hair follicles become smaller and produce thinner, shorter, and less pigmented hair. This condition is also known as male or female pattern baldness and is caused by a combination of genetic and hormonal factors. It is the most common form of hair loss and typically occurs in a predictable pattern, with hair thinning and receding at the temples and crown of the head.
17.
Trichoptilosis is the technical name for
Correct Answer
B. Split ends
Explanation
Trichoptilosis is the technical term used to describe split ends. Split ends occur when the hair shaft becomes damaged and splits into two or more strands. This can be caused by various factors such as heat styling, chemical treatments, and excessive brushing. Split ends are a common hair problem and can make the hair appear frizzy and unhealthy. Trichoptilosis is often used by professionals in the hair industry to refer to this specific condition.
18.
The medical term for dandruff is:
Correct Answer
A. Pityriasis
Explanation
Pityriasis is the medical term for dandruff. Dandruff is a common condition characterized by flaking of the scalp, resulting in white or yellowish flakes of dead skin. Pityriasis refers specifically to the excessive shedding of skin cells from the scalp, leading to the visible flakes associated with dandruff. Pediculosis refers to an infestation of lice, tinea refers to fungal infections, and monilethrix is a rare genetic condition affecting hair growth. None of these terms accurately describe dandruff.
