Enzymes function most efficiently at the temperature of a typical cell, which is 37°C (98.6°F). Increases or decreases in temperature can significantly lower the reaction rate. What does this suggest about the importance of temperature-regulating mechanisms in organisms? Explain.

Thermoregulation is very important for enzymes, since there are only very specific temperature ranges for enzymes to function optimally. If not met, enzymes might denature (or change in form) and not be useful for metabolism.

the correct answer is:

a population changes in response to a change in the environment.

brain development. a child's brain undergoes an amazing period of development from birth to three—producing more than a million neural connections each second. the development of the brain is influenced by many factors, including a child's relationships, experiences and environment.
