Explanation:

Almost all eukaryotic proteins are subject to post-translational modifications during mitosis and cell cycle, and in particular, reversible phosphorylation being a key event. The recent use of high-throughput experimental analyses has revealed that more than 70% of all eukaryotic proteins are regulated by phosphorylation; however, the mechanism of dephosphorylation, counteracting phosphorylation, is relatively unknown. Recent discoveries have shown that many of the protein phosphatases are involved in the temporal and spatial control of mitotic events, such as mitotic entry, mitotic spindle assembly, chromosome architecture changes and cohesion, and mitotic exit. This implies that certain phosphatases are tightly regulated for timely dephosphorylation of key mitotic phosphoproteins and are essential for the control of various mitotic processes. This review describes the physiological and pathological roles of mitotic phosphatases, as well as the versatile role of various protein phosphatases in several mitotic events.

Answer:

2(n+12) = 3/2 (2n+12)

2*2(n+12)=3(2n+12)

4n+48=6n+36

48-36=6n-4n

12=2n

12/2=n

Why are there usually fewer organisms in the top levels of an energy pyramid?

tatuchka [14]

Most organisms in the top levels of an energy pyramid require more food than those on lower levels. On top of this, each level of the pyramid looses energy gained from food. This means that there needs to be more lower leveled organisms for the ones on top to eat in order to gain enough energy. Because of this, there's only enough food for a few of these types of organisms.

I hope this helped! There are probably a few more details you can add, but this is the overall reason :)

zaharov [31]

The answer is heterozygous. It means that she has two different alleles for one specific gene. And homozygous means that it has two same alleles for one specific gene. Heterogenous/homogenous means the different or same between organisms.
