1. how many hairs does the average person shed per day?

Explanation:

For the first two - part questions, one would typically label the parts of a hair strand and hair in skin based on knowledge of hair anatomy. For the third question, the average number of hairs a person sheds per day can be found through general biological knowledge or by referring to the provided web - source. A strand of hair has parts like cuticle, cortex, and medulla. Hair in skin involves structures like hair follicle, sebaceous gland, etc. The average number of hairs shed per day is around 50 - 100.

Answer:

1. For the hair strand diagram: From outside to inside, possible labels could be cuticle, cortex, medulla (if present), and pigment granules (if applicable).
2. For the hair in skin diagram: Labels could include hair shaft, hair follicle, sebaceous gland, arrector pili muscle, and dermal papilla.
3. The average person sheds 50 - 100 hairs per day.
