Blood plasma is the blood constituent which makes up most of the volume of blood. The blood plasma is 55 percent of the total blood and 45 percent is formed by other constituents which includes RBC and WBC. Blood proteins is a part of plasma which means they are less than that of plasma in the blood.
The idea of evolution is that the species change over time. The proposed mechanism of evolution is natural selection. Natural selection favors inheritable traits, suitable (adapted) for survival and reproduction. Organisms with such traits will tend to leave more offspring than others, and thus will evolve over time.
Some of the people that influenced Darwin are:
• Lamarck who first proposed that humans evolved from a lower species through adaptations over time
• Malthus, economist who explained that population grows faster than food production could sustain. So, Darwin proposed that only individuals that have favorable adaptations would survive.
Some of the things observed when a human red blood cell is placed under a microscope are:
- They have a donut shape
- They look like biconcave discs
- The presence and/or absence of a nucleus
<h3>What is a Microscope?</h3>
This refers to the lab tool that is used to view very small objects in detail to find out their properties.
Hence, we can see that although your question is incomplete, a general idea of things that can be observed when a human red blood cell is placed under a microscope was discussed.
