According to Chargaff's rule, the base pairing in the DNA and RNA is fixed. Adenine always pairs with Thymine in DNA and Uracil in RNA. Guanine pairs up with cytosine. This complementary base pairing is universal and constant. That's why amounts are also equal. It means if cytosine is 20% in any DNA sample, then amount of guanine would be 20% as well.

An overlap in the niches of two species will most frequently result in interspecific cooperation A a hybridization of species B

lara [203]

Answer:

The correct answer is D. interspecific competition

Explanation:

Niche overlap occurs when two species share a same niche and use the same resource. So niche overlap most frequently leads to competition between these two species called interspecific competition.

So In interspecific competition, the individuals of two different species fight for the same resource present in their niche for their survival. For example, lions and leopard share the same niche because they prey on similar types of animals like deer, wild pigs, etc.

So here niche overlap lead to the competition between these two carnivores. In interspecific competition, one species is more successful than other.
