How does segmentation enhance annelid locomotion?
segmentation creates repeating body structures so the entire organism functions in synchrony.
segmentation allows specialization of different body regions.
neural segmentation allows annelids to localize sensations.
muscle contractions can be localized to specific regions of the body to coordinate movement.

the answer is c.) there is a warm front in region a and a stationary front in region b.

digestion

it excretes wastes

the answer is true when observing or determining population size, a direct observation is use, in which each organism is counted in a population or in an area. one benefit of this measure is that you get the exact population count but it will take a long time to  determine  the  size  of a  population.
