D- The small intestine is very long and thin. This helps increase the amount of surface area of the small intestine, so it can fully absorb the nutrients in the food. The villi are thin walled to allow the most amount of nutrients to be absorbed as possible.

The correct answer is:

D .Villi in the small intestine have thin-walled capillaries to make the absorption of nutrients more efficient.

Explanation:

The small intestines are well adjusted for absorbing nutrients during digestion by being very long, having villi and microvilli that enlarge surface area, using muscular contractions to move and mix food, and raising and housing digestive enzymes and bile that aid the breakdown of food. The inner surface of the small intestine is not flat but thrown into circular folds, which not only enhance surface area but aid in preparing the ingesta by acting as baffles. Villi: the mucosa makes multitudes of ridges which project into the lumen and are satisfied with epithelial cells.

coldgirl [10]

Answer:

Keratinocytes are located in the stratum basale in the epidermis and the hair follicle of the dermis. This statement is correct.

Explanation:

Keratinocytes are in the stratum basale of the epidermis, which is the deepest layer of the epidermis; from this layer, they ascend to the stratum spinosum, then to the stratum granulosum, then to the stratum lucidum if the skin is thick like the one that is in our hands or soles, and lastly they end in the stratum corneum. While the keratinocytes move from one layer to the next one, they change their characteristics.

Keratinocytes are also in hair follicles, they are similar to the keratinocytes from the dermis, but have some differences, such as their reproduction capacity.
