Answer:Phosphorylation cascades are similar to a row of dominoes falling down, instead of one domino knocking down the next, a phosphate being added activates the message. In this way, a series of different _(phosphate group) are each _(added ) after another. Inactive protein kinase 1 gets a __(phosphate group_)___ added and now it is active protein kinase 1. Active protein kinase 1 transfers a (phosphate group) and now inactive protein kinase 2 is now ___(active)_____. This continues until the desired (protein ) is activated to cause a cellular response.
Explanation:
Answer:
The mentioned parental types are c+m- and c-m+. Thus, the recombinants will be c+m+ and c-m-.
Now, the given distance between c and m is 8 map units. Thus, the recombinant frequency is 8% or 0.08.
The total recombinants from 1000 plaques will come out to be 80,
Thus, the recombinants of each type will be 40.
Total parental type will be 920, and therefore, each parental type count will be 460.
Thus, expected c+m- = 460, expected c-m+ = 460, expected c+m+ = 40 and expected c-m- = 40.
<span>The answer is a certain required chemicals must be actively
transported. Blood brain barrier is a
selective membrane that separates blood circulating from the brain and the
fluid of extracellular in the central nervous system. This is also called a
filtering mechanism, the capillaries that carry blood to the brain and spinal
cord tissue blocking the path way of the certain substance.</span>
Polar ice cap
Explanation:
The polar ice cap is an area on the earth that extends from 66.5° north and south of the equator to the poles.
The polar ice cap is an area of very low temperature and the surface is mostly covered by ice.
- The vast polar ice caps the earth's northern and southern limits.
- This is the region of the Arctic and Antarctic circle.
- This region receives diffused solar radiation from the sun.
- This is why they rarely warm up.
- The region of the equator has no ice because they receive direct sunlight.
- The soil here is frozen.
