D. Bar graph
Here is a discussion
Answer:
b. it involves a physical exchange of segments from homologous chramosomes.
Explanation:
Crossing is a phenomenon involving homologous chromatids. It consists of the breaking of these chromatids at certain points, followed by an exchange of corresponding pieces between them.
Exchanges cause new gene sequences to appear along the chromosomes. Thus, if on a chromosome there are several genes combined in a certain sequence, after the occurrence of crossing the combination may no longer be the same. So when thinking about crossing, it is common to analyze what would happen, for example, about the combination of the allele genes "A" and "a" and "B" and "b" in the pair of homologues.
Answer:
would it be the shortness
Explanation:
A. All harness energy of sunlight through the process of photosynthesis
Answe: Mutations can cause instant adaptations, while natural selection is the process by which adaptations occurs over a series of generations. Adaptations are changes or processes of changes by which an organism or species becomes better suited for its environment. A mutation is an alteration of the DNA sequence.
