alculate NEP before the outbreak and identify the most appropriate conclusion about whether the forest was a carbon sink or a carbon source. Calculate NEP before the outbreak and identify the most appropriate conclusion about whether the forest was a carbon sink or a carbon source. Before the outbreak, the forest was a carbon sink because NEP was less than 0. Before the outbreak, the forest was a carbon sink because NEP was greater than 0. Before the outbreak, the forest was a carbon source because NEP was less than 0. Before the outbreak, the forest was a carbon source because NEP was greater than 0.

the element that provides strength to the exoskeletons of clams and oysters is phosphorus. this is so because calcium carbonate is the main component in the shells.

explanation:

a motor homunculus represents a map of brain areas dedicated to motor processing for different anatomical divisions of the body.

homunculus represents the importance of various parts of your body as seen by your brain. as a result, they take up a lot of brain space. although the cortical homunculus is a curiosity, penfield's work in mapping the brain's relationship to the body was invaluable.

false because ozone (o3) depletion does not cause global warming, but both of these environmental problems have a common cause: human activities that release pollutants into the atmosphere altering it.
