In a cancer patient undergoing chemotherapy, the decision to utilize a csf capable of specifically stimulating the production of only the granular leukocytes would require that the csf acts exclusively on ______.
Myeloblasts.
Explanation:
All right, there is a triple co-relation here. First of all, we have a problem we require to stimulate the production of only granular leukocytes. They are white-blood cells that attack infections. Their relation to myeloblasts is that granular leukocytes develop from myeloblasts. Now, to increase their production we would require a CSF that would be capable of stimulating the growth of myeloblast to increase the presence of granular leukocytes.
If you look at the the graph, C points to the time period after mammals appeared. Since birds are mammals, they should have appeared after the time that mammals first came to be on Earth.

For example the transition stage from wake to sleep where we see a gradual reduction in consciousness with fuzzy, halfway states in between conscious and unconscious.
