never [62]

Answer:

convergent evolution

Explanation:

If we have two species that share a similar trait or look alike a lot, but they live in places isolated from each other, and they only have a very distant relation, then it is a case of convergent evolution. This type of evolution occurs with species that are not closely related, but they live in environments where having the same or very similar traits is advantageous. This can often lead to a confusion when looking at the species only on the outside, and it can be very misleading. As an example we can take the sabretoothed predators that existed in the past. Both the smiloden and the thylacosmilus had large saber like teeth, and even their bodies looked very similar, so one would assume that they are closely related, but that was not the case. The smilodon was part of the cat family, while the thylacosmilus was a marsupial, making them very distantly related. They developed same same and some very similar traits because their environment created the evolutionary pressure for those traits to develop as they were advantageous, despite them evolving in totally different places and separately.

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.
