Answer;
all individual variation is due only to environmental factors
A population of organisms will not evolve if all individual variation is due only to environmental factors.
Explanation;
-Evolution of organisms is influenced by several factors which include; natural selection, random genetic drift, mutation, and gene flow.
-Mutation is a random heritable change in a gene or chromosome, resulting from additions, deletions, or substitutions of nitrogen bases in the DNA sequence. Gene flow works to decrease the variation between the two populations.
-Genetic drift is the random change in allele frequency from one generation to the next.. Natural selection is the process by which some organisms have a greater chance of surviving and reproducing than others due to features that are better adapted to the environment.
I think the answer is both B and C,because he needs to confirm his findings by repeating his analysis to make sure he didn't do any mistake in the first process but also needs to analyse fossils found in the same area, because he might find evidence of more fossils from the same time,that would support the hypothesis that there was a community there. You need evidence of a community,because by having multiple fossils of the same age,you could prove the one that you found is indeed older.
Answer:
A
Explanation:
mitosis plus answer b and c are the same so those can't be correct.
