Answer:
D. Only the adrenal medullae
Explanation:
The adrenal medulla is the inner region of the adrenal gland. It consists of the modified sympathetic ganglion of the autonomic nervous system and develops from the same embryonic tissue as all other sympathetic ganglia. The cells of the adrenal medulla lack axons and are [present in the form of clusters around large blood vessels.
The chromaffin cells of adrenal medulla serve the endocrine function. These cells are innervated by sympathetic preganglionic neurons of the ANS. The adrenal medulla secretes epinephrine and norepinephrine which are called neurohormone as being secreted by neurons.
Carbon dioxide should be the answer considering its a huge focal point in our climate today and how it affects it.
C. producer, the corn creates its own 'food' with photosynthesis. It's easier to remember as a flow chart producer(typically plants)->primary consumer(mostly herbivores)->secondary consumer(predators and other meat eaters) and decomposers(usually fungus) eat basically everything.
