I think but I do not know it refered to as being repetitive
The important
indicators of hemotopoietic function and a number of clinical parameters, such
as blood oxygen-carrying capacity, inflammation, and hemostasis are circulating
blodd cell coutns and indices. By performing whole-exome sequence association
analyses of hematologic quantitative traits in 15,459 community-dwelling
individuals, followed by in silico replication in up to 52,024 independent
samples, we identified two previously undescribed coding variants associated
with lower platelet count.
Answer:
70% solution is more effective
Explanation:
The 70% solution is more effective at inhibiting microbial growth than the 100% solution of the ethyl alcohol.
This is because the pure ethyl alcohol coagulates the protein that is in contact with it.
Also, pure alcohol will tend to evaporate faster than the 70% solution of the ethyl alcohol and it will not be that much effective.
The answer is d. The population of light-colored moths decreased and the population of dark-colored moths increased.
<span>Peppered moth color variation is a good example of natural selection. During the Industrial revolution, due to pollution, trees become darker in the urban area. Light-colored moths were, thus, easy prey. The dark-colored moths were able to camouflage on dark trees and avoid predators. The phenomenon is known as industrial melanism. So, in polluted urban areas, the number of dark-colored peppered moths increased. In the clean environment, were much effective in hiding from predators and they outnumbered the dark-colored moths.</span>
