Answer:
Dehydration from flu
Explanation:
On centrifugation, blood forms different regions plasma region, the Buffy coat and the hematocrit which contains the erythrocytes or the red blood cells.
The normal range is between 37-52 percent of the total whole blood.
Any value below shows anemia and any value above indicates polycythemia.
Polycythemia is usually a sign of doping in athletes however for this elderly patient. It must have been caused due to dehydration from the flu.
The process is photosynthesis.
Hello!
Natural selection is the way that animals evolve.
The theory of natural selection is that the animals that do not have a specific trait to survive in their environment will die. The animals that do have the trait will survive. The animals that survive will then pass the trait down to their offspring, who will also likely survive because they have the trait. This is how species evolve and continue to survive in their environment.
The species evolve because only the fittest survive (this is known as "survival of the fittest"). The animals that do not have the needed traits will die and they cannot have offspring.
I hope this helps answer your question! Have a great day!
A Golgi apparatus receives proteins from the rough endoplasmic reticulum. The Golgi apparatus modifies, sorts, and packages the proteins to be sent out of the cell to be used. Hope this helps! :)
Red blood cells will swell and burst. The
reason behind this is that red blood cells are okay when they are in
the plasma (the watery part of the blood) because the solutes in plasma
are so well balanced that plasma is rendered isotonic. An isotonic
solution is a type of solution that has the same salt concentration as
its surrounding environment and thus the substances around it e.g. cells
neither gain nor lose water. In the blood plasma, the red blood cells
neither lose nor gain water and so they remain intact.<span>However distilled
water is hypotonic (has less or no solutes) and therefore osmosis will
take place when red blood cell which have a higher solute concentration
are placed in it. Water molecules will leave the distilled water and
pass into the red blood cells through the semi-permeable membrane of the
cells in an attempt to equalize the difference in osmotic pressure on
either side of the membrane. In so doing, water will accumulate in the
cell which will then swell to capacity and ultimately burst.</span>
