C that is formation of red blood cells eg leukemia in which the bodys ability to produce red cells is disturbed
Answer:
The evolution of a species is driven by many evolutionary mechanisms two of which are: natural selection and the genetic drift.
The natural selection selects the species or the alleles which increase the reproductive success of the species in a given environment whereas the genetic drift cause evolution by randomly selecting the alleles based on the sampling error. The genetic drift selects the alleles or species by chance and not on the beneficial and harmful basis.
In the given question, If natural selection favours the one trait of the species on the basis if it provides fitness then it could result in a genetic drift of alleles of another trait as it is purely based on the chance.
Answer;
-An influenza virus particle
Explanation;
-An influenza virus particle is bigger in size compared to a ragweed pollen grain. Influenza virus particles have a size of 80–120 nm. However, the length of each particle varies considerably, owing to the fact that influenza is pleomorphic, and can be in excess of many tens of micrometers, producing filamentous virions.
-On the other hand, researchers found that ragweed pollen grains release SPPs in the size range of 0.5–4.5 μm, small enough to reach lower airways.
