Cells are constantly dividing and replacing old or damaged cells.
Sexual reproduction produces far more genetic variation than asexual reproduction. I’m asexual reproduction, only one organism is needed. In this process they copy their own DNA and create an exact copy of themselves. So, if you think about it, all the offspring ever created by that one organism is going to have the same genetics as it. They’re all going to be identical. There is no variation, or differences, between any of the offspring and the original organism. Bacteria reproduces this way, although through binary fission, they can sort of reproduce sexually.
Sexual reproduction results in genetic variation. Two organisms are needed to create offspring. An egg cell and a sperm cell are needed from a female and male organism to create the new organism. Since two organisms are required, their offspring will be a mix of their DNA. This will create variation between offspring. Every new organism will have different genetics.
This is why more advanced organisms like plants and animals have different DNA even if they are the same species.
Carbonates and hydroxides. Base salts.
Nearly flat and Rhinos do not really reproduce rapidly.
hope it helps
The correct answer is: A predator prefers one phenotype to another.
There are variations in every population meaning that individuals are different at both, genetic and phenotypic level.
Natural selection is one of the evolutionary mechanisms, meaning that it changes allele frequency over generation. There must be genetic variation in population so that the natural selection can act. Natural selection acts on an organism’s phenotype (observable features) by favoring the most suitable ones (for survival).
If predator prefers one phenotype to another, another phenotype helps organisms survive and reproduce so that organism is better adapted for the environment. Natural selection ”selects” the best adapted trait.
