Answer:There are more species in the tropics because tropical ecosystems have more niches. However, the number of niches in an ecosystem is determined by the number of species in that ecosystem.

Answer:
The correct answer is option a. "heredity".
Explanation:
Nowadays is still not clear the degree at which heredity and environmental factors affect social behaviors such as aggression. In this example Constance is focused on aggression being caused mainly by genetic inheritance. On the other hand, Agatha believes that people are capable of freely making voluntary choices. Therefore, it could be assumed that Constance rejects environmental factors, while Agatha rejects heredity as the factor that affects aggression.
Answer:
2 is a, 1 is b, 4 is d, and 3 is c
Explanation:
Multiple sites on the DNA during DNA replication allow the process to happen much faster than it would with a single site.
Answer:
B) The tall version of the gene is dominant to the short version of the gene.
Explanation:
In the question, its given that both the pea plants are purebred for genetically for height. Therefore, we can already pre-determine the combination of letters for each gene, since purebred means that both letters in the combination are the same.
Tall genes: TT
Short genes: tt
Inputting these into a punnet square would give a result of four possible combinations for the offsprings height:
Tt, Tt, Tt, and Tt (doesn't matter which letter is first)
If <em>all</em> the offspring are tall, despite there being a purebred short parent, then we can assume that the tall gene is dominant to the short gene. (Dominant alleles when paired with sub. alleles have the result of the dominant gene actually showing up. In this case, Tt, where the plant is tall due to the T allele regardless of the presence of the short allele t.)
Hope that helped!
