Homeostasis is the maintenance of a relatively constant internal state. It is the process by which living organisms maintain a state of equilibrium in their internal environment. The organs that take part in homeostasis include: the skin, kidney and liver. These organs works together to maintain a stable internal environment.
<u>Explanation:</u>
One physical difference between the hands and feet is that the human hands appear to be more flexible than our feet. Also, in terms of size, our feet are smaller than our hands.
Let's assume that our feet become as flexible as our hands and the hands less flexible, it would affect the function they perform.
- If for example, we were to walk with our hands we will fail to achieve stability.
- And if for example, we decide to grab hold of items with our feet we will be unable to do so.
It is also reasonable to expect other primates to have hands and feet that differed from ours because they are necessary so they can adapt to their environment just like humans too.
