Answer:
B) Hypogranular neutrophils
Explanation:
Myelodysplastic syndrome occurs due to a disordered production of blood cells in the bone marrow that die before they are even released into the bloodstream. This syndrome is of great clinical significance as they may progress to Acute Myeloid Leukemia. Generally, when this disease has pre-leukemic features it may include hypogranular neutrophils which is one is a feature of neutrophil dysplasia commonly observed in myelodysplastic syndromes.
The important point is that the surface area to the volume ratio gets smaller as the cell gets larger and as volume increases, surface area to volume ratio decreases. The larger a cell, the less easily it can get rid of waste and it also has more trouble getting water, nutrients and gases in. That is why we do not see giant cells. Instead we see multiple cells in larger organisms.
One way to increase surface area is to flatten the cell. That is why red blood cells are flat discs, instead of spheres. Another way is elongation. That is why many bacteria are rod shaped, and why neurons are elongated. In fact, the human body relies on the same principle to adapt to climate. Long tall and lean folks with long arms and legs live in East Africa, because such shapes increase surface area to get rid of excess body heat to avoid heat strokes. Europeans and Asians adapted to cold climates, in contrast, have shorter arms and legs and rounder torsos to minimize surface area. to conserve body heat.
Answer:
C. To confirm that the alternative fuel is cleaner than fuels currently used
Explanation:
The current fuels from mining, cutting down trees and even transportation is bad for the atmosphere. These fuels cause climate change which could potentially bring a lot of dangers. The reason scientists would conduct research on a newly alternative fuel is so that the fuel would be a lot more cleaner which could prevent the dangers that are to come.
