What effect on the body does a lack of insulin have?
ludmilkaskok [199]
Insulin is such a vital secretion of the pancreas in the human body that without it, our body would not function normally. It is responsible for breaking down the food we eat and converting it to energy and then storing that energy. Lack of insulin means that the pancreas are not producing insulin which leads to diabetes. That means that there is a concentration of glucose in the blood rather than being distributed to cells to carry out functions. This can lead to kidney failures,  nerve damaging stomach problems and problems in the eyes.

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.
