Some members of daphnia, a water flea, have a genetic mutation that causes them to prefer warmer environments. these members reproduce and pass genetic changes to their offspring. the next generation will occupy warmer environments not previously occupied by this species. this is and example of:
- adaptation -homeostasis -irritability -all choices are correct

Adaptation is correct

Explanation:

Remember all the species changes little by little because of the genetic changes (like in this case) or because need to adapt the quantity of food (in some seasons like camels) or because they need to adapt to environmental conditions (like in hotter summers or colder winters in some regions).

In all these cases, the changes occurred through the pass of time and could be a result in changes in their morphology or physiology.  

yes

explanation:

voluntary muscles are controlled by the cerebellum.
