I believe you are correct. 

A and C are not always reliable a they could pay these people to do a testimonial 

It is definitely not B; Just because they have an expensive research facility does not mean that their research is amazing.

One reason native plants are declining is that the invasive plants absorb nitrogen from the soil about twice as fast (α = 2). Ho
Dmitry_Shevchenko [17]

Answer:

α = 0 if β= 0

Explanation:

If both species want to persist in the same environment and their niches are also over lapping then both of the co-efficient values should be equal. There are two possibilities on these values for persistence. One is that one should compromise to the change produced by the invasive specie and two is that the new specie should compromise if he wants to stay (<em><u>Assuming that there is no competition</u></em>). In this way their niches won't overlap to a greater extent and therefore better chances of survival for both.

A milk snake looks similar to the deadly coral snake. This is an example of A) warning coloration adaptive radiation B) cryptic
Damm [24]
In this case, c) mimicry is the answer. In Batesian mimicry in which harmless animals mimic toxic animals. In this case, I assume the milk snake is harmless and the coral snake is venomous. Since the milk snake has a trait similar to deadly coral snake, less animals would eat it thinking it is dangerous. Over time all the milk snake that look like the deadly coral snake would survive leading to evolution by natural selection. This would lead to more and more milk snake mimicking the resemblance of the deadly coral snake.

a) The deadly coral snake has a warning color adaptive radiation. If the question had described the environment and how the snaked adapted to the environment via warning coloration. This would've been correct.

b) cryptic coloration is more about camouflage with the environment. If the question had state how a certain feature help one of the animals blend into the background. This would've been correct.

d) I'm not sure whats different between this and a so i'll consider them both the same.
