Answer:
b: 8;8
Explanation:
Mitotic or meiotic cell division constitute the m phase of the cell cycle. At the end of the m phase, the new cells enter the interphase stage of the cell cycle. The interphase is further sub-divided into;
- <em>the
phase,</em> - <em>the
phase,</em> - <em>the S phase; and</em>
- <em>the
phase</em>.
The
phase is essentially a resting phase. Cells that do not need to divide except when necessary move into this phase after exiting the m phase.
Actively dividing cells enter the
phase after exiting the m phase. Cell development and growth takes place. From there, the cells enter the S phase where DNA replication/synthesis takes place. The cells then enter the
phase where proteins are synthesized in preparation for division or m phase.
At the S phase, the amount of DNA a cell carries is doubled but the chromosome number remains the same. For example, if a cell enters the S phase with 2 g of DNA containing 10 chromosomes, at the end of S phase, the amount of DNA would have come 4 g while the number of chromosomes will remain 10.
Hence, if the average amount of DNA in the assayed cells immediately after mitosis is 4 picograms, the amount would be 8 picograms at the end of S phase and will still remains 8 picograms at the end of
phase.
The correct option is b.
Non-random mating is assortative mating. It is a pattern and form of sexual selection in which individuals with similar phenotypes mate with one another more frequently than would be expected under a random mating pattern. non-random mating can act as an ancillary process for natural selection to cause evolution to occur. It’s also bad for evolution because any departure from random mating upsets the equilibrium distribution of genotypes in a population. Recombination is a process by which pieces of DNA are broken and recombined to produce new combinations of alleles. recombination is important to somatic cells in eukaryotes because it can be used to help repair broken DNA. recombination by itself does not cause evolution to occur. Rather, it is a contributing mechanism that works with natural selection by creating combinations of genes that nature selects for or against. Non-random mating affects the evolution more than recombination
The comparison and contrast between the raft and the shore has something to do with freedom. On the river, Huck and Jim are free from the legal, societal and cultural structures which is the opposite if they were on the shore.

the answer would be A Do not run out because they are renewable
3. cell wall
The cell wall is a rigid supporting structure.
