Answer: A. scalp hairs grow constantly throughout life.
Explanation:
Hair is a squamous keratinized epithelium which is consist of multi-layered flat cells. Hair are made up of protein called "keratin".

Scalp hair growth rate depends on three main factors including sex (female hair grows faster than male), age (hair growth slows with age), and ethnicity (Asian hair grows slower than Caucasian hair).
Scalp hair growth stops because of follicle devitalization when the hair length become two or three feet.
Hence, the correct answer is A. "scalp hairs grow constantly throughout life".

Answer:
The correct answer is- Resistance
Explanation:
The ability of any organism in a population to tolerate a chemical like insecticide, pesticide or antibiotic which is designed to kill it or slow its reproduction is called resistance.
For example, the antibiotic resistance is seen in some bacteria like MRSA(Methicillin-resistant staphylococcus aureus). They gain this resistance because they have some variant traits in their genome which provide them resistance against these chemicals.
These individual are selected through natural selection when the environmental condition changes and become adverse. So the correct answer is resistance.

A. Total Vit D intake = 1150000212 IU
B. Yes he met his RDA and does not need any supplements
C. 191666702%
Explanation:
I μg = 40 IU
1 oz = 28.35 g
I g = 1000000 μg
A. Low-fat Yoplait yogurt-2 μg = 2 * 40 IU = 80 IU
Cheerios cereal-1 μg = 40 1U
Coffee with milk-07μg = 0.7 * 40 = 28 IU
Turkey sandwich on whole-wheat bread with large garden salad-0.4 g = 0.4 * 1000000 * 40 IU = 16000000 IU Grilledd pork chop. 8 oz = 28.35 * 1000000 * 40 = 1134000000 IU
mashed potato and a side of gnled mixed vegetables-1.6 μg = 1.6 * 40 = 64 IU
Total vitamin D intake = 1150000212 IU of Vit D.
B. Since his RDA is 600 IU, he met his RDA and does not need any supplements of Vit D.
C. Percentage of his RDA Vit D intake = (1150000212/600) * 100% = 191666702 %
