Chemotaxis is defined as a response to a chemical gradient of attractant or repellent molecules in the bacterium's environment.
if the environment contained a gradient of attractants, which bacterium would be most likely to have a net movement toward the signal? (choose the motility deep test result as your indicators.) select one: a. the motility deep has a single green line that corresponds to where you had stabbed the needle.
b. the motility deep is colorless.
c. the motility deep is entirely red.
d. the motility deep has a single red line that corresponds to where you had stabbed the needle.

Acid Rain goes in lakes and other water sources where animals drink water. When drinking for acid rain water animals get sick and plants dependent on water sources die off.
Two diverse species<span> naturally breed an offspring, and selective pressures favor </span>new<span> traits in a given environment, (they evolve). hope this helps</span>
