Lotions applied during winter season moisturize the skin very quickly. What could be the reason for this?
MrRissso [65]

The right answer is D.

The absorption of molecules at the level of the skin is carried out by passive diffusion for the molecules of low molecular weight (lower than 400 Da), the skin being covered with a lipoprotein film rich in water by its stratum corneum, rendering it little-permeable.

This absorption may be variable according to factors related to the skin such as stratum corneum's thickness, the state of hydration, the presence of cutaneous lesions or individual variations.

External factors may also modulate percutaneous absorption such as contact time, iontophoresis or the presence of specific adjuvants.

Natasha_Volkova [10]

Answer:

<em>The correct option is B) regulation of mitosis</em>

Explanation:

Cancer can be described as a group of diseases which result from uncontrolled, abnormal cell division. The cell division by which the cells divide (except sex cells) is termed as mitosis. Hence, scientists will be studying the regulation of mitosis if they are to find a cure for cancer.

Other options like option A are not correct because only sex cells divide by meiosis. Hence, regulation of meiosis will not cure cancer.
