Lung diseases........................
Answer:
a. the blood pressure decreases. the bblood in the A that is the artery is higher as the artery carries the oxygenated blood which is directly pumped out of the heart.so the artery's pressure is higher where as the capillaries pressure decreases when compared with artery. the blood in the capillary flows slowly and smoothly as capillary needs time to exchange the substance between the body cells and the blood. the vein carry the deoxygenated blood back to the heart so their pressure is low.
b.the highest pressure is found in the artery because it carries the oxygenated blood and the heart pump the blood with great force thus tge artery have the highest pressure . and it also wanted to transport the oxygen quickly to other parts of the body.
c. valves. these prevent the backflow of the blood in capillary as the blood moves against the gravity.so valves prevent the blood from going back . therefore the valves help the blood in veins to move back to heart. (not sure)
Answer:
D.
Explanation:
soak in warm water, scrape up food clean with sanitizer rinse and towel dry
Why because,
Soaking will enable leftovers to remove with ease
So first soak in lukewarm water
The answer is d. allowing the good genes to slowly <span>spread through the population.

<span>Natural selection is the differences in survival
and reproduction as the consequence of differences in genotypes and, consequently, phenotypes. It is one of the factors of evolution that affects a frequency of different variations. </span><span>In natural selection, genotype variations that
will increase the chance of survival and reproduction of some organism are
preserved and will be inherited Thus, "good genes" will be inherited. But, as the evolution, it will be slow process, since rarely evolution happens quickly.</span>
Answer:
The mice population do not involve in the same line.
Explanation:
The gene flow refers to the transfer of the gene from one population to another population and natural selection is the mechanism in which the survival rate and reproduction of the population are decided by the nature following the rule of the survival of the fittest.
In the given question, the mice population got separated due to the river which acted as a barrier between the mice population. The presence of this barrier reduces the chances of the gene flow between them as it is impossible for the mice population to cross the river.
As a result of this, the mice population will start surviving in different regions on both the sides of the river where it is not necessary that the same environmental pressure will act on the population of the mice.
Thus, the mice population do not evolve in the same line.
