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.

WILL BRAINLIST CORRECT ANSWER PLATO
Dmitrij [34]

Answer:

I believe the first one would be incomplete dominance, the second would be multiple alleles, and the third would be codominance.

Explanation:

The first one would be incomplete dominance because the child has a blend of the man's straight hair and the woman's curly hair, but neither of two hair types are completely dominant (if that makes sense).

The second one would be multiple alleles because, well, there are multiple alleles listed (more straightforward than the other two).

And the third one would be codominance because the traits of red color and white color are equally dominant.

An example of a substance that is modified through this process is insulin.
