2. Sometimes a few individuals are
isolated from the rest of the
population and can have very
different gene frequencies. This is
called

macro-evolution

Explanation:

This happens when evolution occurs because of separation of a population.

answer: the rate of diffusion increases with increase in temperature.

increase in temperature, increases the molecular/particles speed (kinetic energy. diffusion means movement of particles through the material.

generally, the heavier the particle the more it interacts with the environment and more the temperature matters. so higher temperature results in higher diffusion.

i believe the answer is c. "baking" is the gerund, while "baking blueberry muffins" would be the gerund phrase. hope this ! : )
