  • 2. 

    Gray hair is caused by the absence of melanin.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    Gray hair grows from the hair bulb in exactly the same way that pigmented hair grows and has exactly the same structure, but without the melanin pigment.

    Rate this question:

  • 3. 

    Name the outside layer of the hair.

    • Cuticle

    • Follicle

    • Cortex

    • Medulla

    Correct Answer
    A. Cuticle
    Explanation
    The cuticle is the outermost layer of the hair. It is a thin, transparent layer that acts as a protective barrier for the hair shaft. The cuticle is made up of overlapping scales that help to prevent damage and keep the hair shaft moisturized. It also plays a role in giving the hair its shine and smoothness. The other options, follicle, cortex, and medulla, are not the correct answers as they refer to different parts of the hair structure.

    Rate this question:

  • 4. 

    Trace evidence is a type of circumstantial evidence, examples of which include:

    • Hair found on a brush.

    • Fingerprints found on a glass.

    • Blood drops on a shirt.

    • All of these choices

    Correct Answer
    A. All of these choices
    Explanation
    The given correct answer is "All of these choices". This means that all of the examples mentioned - hair found on a brush, fingerprints found on a glass, and blood drops on a shirt - are types of trace evidence. Trace evidence refers to any small, physical material that is left behind at a crime scene and can be used to link a suspect to the crime. In this case, all three examples mentioned are types of physical evidence that can be collected and analyzed to help solve a crime.

    Rate this question:

  • 5. 

    During the ________ or growth phase, new hair is produced. The hair actively manufactures new keratinized cells in the hair follicle. During this phase, hair cells are produced faster than any other normal cell in the human body.

    • Catagen

    • Telogen

    • Anagen

    Correct Answer
    A. Anagen
    Explanation
    The average growth of healthy scalp hair is about 1/2 inch per month. Scalp hair grows faster on women than on men. Scalp hair grows rapidly between the ages of 15 and 30 but slows down sharply after the age of 50. About 90% of scalp hair is growing in the anagen phase at any one time. For each specific hair, the anagen phase generally lasts from three to five years, but in some cases, it can last as long as ten years.

    Rate this question:

  • 6. 

    The portion of the hair that extends above the skin or scalp.

    • Hair shaft

    • Hair root

    • Hair bulb

    Correct Answer
    A. Hair shaft
    Explanation
    The hair shaft refers to the portion of the hair that extends above the skin or scalp. It is the visible part of the hair that we can see and touch. The hair shaft is made up of dead, keratinized cells that have been pushed up from the hair follicle. It is responsible for giving hair its color, texture, and length. The hair shaft is different from the hair root, which is the part of the hair that is located below the skin or scalp and anchors the hair in place. The hair bulb, on the other hand, is the rounded base of the hair follicle where the hair root begins.

    Rate this question:

  • 7. 

    A Medulla is not present in all hair 

    • True

    • False

    Correct Answer
    A. True
    Explanation
    The medulla is the innermost layer of the hair shaft and is not present in all hair types. Some hair types, such as fine or thin hair, may not have a medulla. Therefore, the statement "A Medulla is not present in all hair" is true.

    Rate this question:

  • 8. 

    The tough outer protective covering of hair.

    • Cuticle

    • Cortex

    • Medulla

    • Follicle

    • Sebaceous glands

    Correct Answer
    A. Cuticle
    Explanation
    The correct answer is cuticle. The cuticle is the tough outer protective covering of hair. It is a thin, transparent layer that surrounds the hair shaft and helps to protect it from damage. The cuticle also plays a role in maintaining the moisture balance of the hair and preventing it from becoming too dry or too brittle.

    Rate this question:

  • 9. 

    Put the layers in order, starting from outside.

    • Medulla, Cortex, Cuticle

    • Cortex, Medulla, Cuticle

    • Cuticle, Medulla, Cortex

    • Cuticle, Cortex, Medulla

    Correct Answer
    A. Cuticle, Cortex, Medulla
    Explanation
    The cuticle is the outermost layer of the hair shaft, followed by the cortex, which is the middle layer, and finally the medulla, which is the innermost layer. This order is important because the cuticle acts as a protective barrier for the cortex and medulla, and the cortex provides strength and structure to the hair. The medulla, although not always present in all hair types, is responsible for the hair's flexibility and elasticity. Therefore, the correct order of the layers from outside to inside is cuticle, cortex, medulla.

    Rate this question:

  • 10. 

    The ________ is the middle layer of the hair.

    • Medulla

    • Cortex

    • Cuticle

    Correct Answer
    A. Cortex
    Explanation
    The cortex is soft, thick and made up of elongated cells. It also contains melanin pigment. The elasticity of the hair and it's natural color are the result of the unique protein structures located within the cortex. The changes involved in oxidation hair coloring, wet setting, thermal styling, permanent waving, and chemical hair relaxing all take place within the cortex.
