Answer:
A step that is not part of natural selection is people select which individuals breed and which ones do not.
Explanation:
Natural selection is a process in which favorable or unfavorable environmental conditions determine the evolution of species, producing differences in their genotype over a long period of time.
As its name indicates, it is a natural selection, in which no intervention by people is contemplated, so that <u>people cannot determine which individuals breed</u>.
Natural selection implies that the characteristics on which the environment influences are inheritable, that there is genetic variability in the population and that the variability of these characteristics implies the ease of reproduction and survival capacity.
<em>The other options do form part of natural selection, since they are based on the three premises of this process:
</em>
- <em>Inheritable characteristics.
</em>
- <em>Genetic variability.
</em>
- <em>The variability of characteristics influences reproduction and survival.</em>
DNA is coiled into proteins,,,,which makes up ur DNA (about 6,400,000,000 basepairs (DNA building blocks) that make up your DNA) basically...and...The way DNA is packaged into chromatin is a factor in how protein production is controlled. so in your nucleus....AGAIN....DNA IS KEPT OR COILED AROUND PROTEIN YET KEPT IN UR NUCLEUS... :)
... i hope this helps somewhat..
Answer:
Cytokinesis
Explanation:
All living cells undergo division, it is the method employed in duplicating themselves. The division of cells involves two major processes viz; karyokinesis and cytokinesis.
Karyokinensis involves the division of the genetic material (DNA) in the nucleus. The chromosomes are initially separated into opposite poles/ends inside the cell. After which the cytoplasm of the whole cell then separates resulting in two daughter cells each having its own genetic material. This process is called CYTOKINESIS.
Although CYTOKINESIS occurs in all eukarotes and prokaryotes, the way it occurs in the eukaryotic plant and animal cells differ in the sense that, in animals, it occurs with the formation of a cleavage furrow as a result of pinching inward of the cell membrane until the two daughter cells form while in plants, a cell plate is formed at the cell's centre and a new membrabe and cell wall is formed around each cell plate.
Birds migrating in the winter would be a behavioral adaptation. The rest of the adaptations would be structural or physiological because they are controlled by mutations in the DNA. <span />
