The law of segregation occurs during meiosis when gamete are formed. At this time, the alleged for each gene segregate from one another. As a result, each gamete contains only one allele per gene.
Dam well i been thru worse L rip
The probability of life evolving into a complex form is one of the factors in the Drake equation. Drake himself estimated that probability as 1.0, for what that's worth.
<span>He had that confidence precisely because descent-with-variation seems pretty certain to be a universe process because it's so straightforward. If you have something that reproduces imperfectly, eventually more complex versions will be the result. Even the "natural selection" part is optional if you were just imagining searching through the vast space of genetic possibilities, but finite resources make selection inevitable.</span>
If the cell grows beyond a certain limit, not enough material will be able to cross the membrane fast enough to accommodate the increased cellular volume. When this happens, the cell must divide into smaller cells with favorable surface area/volume ratios, or cease to function. That is why cells are so small.
simpler answer: Cells are small because they need to keep a surface area to volume ratio that allows for appropriate intake of nutrients while being able to eliminate the cells waste.
