Answer:
Light colored peppered moths decreases in number and dark colored peppered moths increases.
Explanation:
The population of light colored peppered moths decreases whereas the dark colored peppered moths increases in number because the light colored peppered moths are visible to the predator birds whereas the dark colored peppered moths are not visible due to dark coating of the trees so they are saved from the birds and therefore, increase in population of dark colored peppered moths occurs and decrease occur in light colored peppered moths population.
Answer:
C. Characters with little genetic variation will constrain the rate of natural selection
Explanation:
Natural selection can have an effect only as long as there are variations on characters on which it can select upon. Genetic variation is independent of the environment or the needs that a species may have to become better adapted to its changing environment. In other words, genetic mutations are the raw material on which natural selection can work. If there is a low rate for mutations to occur, then natural selection will proceed at a slow pace. The opposite is also true. Since mutation rate may be more frequent at some locations in a gene than at others, it can be predicted that the characters coded in that gene location will be more likely to be affected by natural selection and therefore what phenotype may be molded by natural selection.
Answer:
true!!
Explanation:
A frameshift is when the frames of the three nucleotides shift and an insertion or deletion will do that
Answer:
strengths:The cell model shows all the process involved, and it's easy to understand, even if a person isn't familiar with the process
weaknesses: it doesnt show organelle or rna
