The Cell-Cycle Control System Is Based on Cyclically Activated Protein Kinases. At the heart of the cell-cycle control system is a family of protein kinases known as cyclin-dependent kinases (Cdks). The activity of these kinases rises and falls as the cell progresses through the cycle. I
Answer: 25%
Explanation:
First find the trait that describes the pea shape because that’s what you’re being asked to find. In this case, pea shape is either wrinkled (s) or smooth (S). If the two plants that are crossed are both heterozygous, that means they each have one dominant allele and one recessive allele, which would like this: Ss. By putting both of the Ss genotypes (one Ss for one parent at the top of the board and the other Ss for the second parent down the side of the board) around the punnet square, you get: Ss x Ss= SS, Ss, Ss, ss. You are then asked to find the percent of wrinkles peas, which can only be shown when both alleles are recessive. By looking at the punnet square you can see that that only happens 1/4 times. When you turn that into a percent you get 25% of the plants that have wrinkled peas.
During diffusion the molecules move in constant random motion. <span>The </span>net movement<span> of a substance from a region where it has a higher concentration to a region where it has a lower concentration, due to random molecular motion, is called </span>diffusion<span>. Diffusion is a widespread and important process which occurs in both living and non-living systems. </span>
Answer:
Interkinesis
Explanation:
Meiosis i is the first cell division, where the parent cell divides into two cells. Each of these cells undergoes a second division in meiosis ii, to form a total of four daughter cells.
Between meiosis i and ii there is a rest period. This is called interkinesis. No DNA replication occurs in this stage (unlike in interphase). What does happen is that the nuclear envelopes temporarily reform between telophase I of meiosis I and prophase II of meiosis II Not all organisms have the interkinesis stage, some proceed directly to meiosis II after meiosis I
