It is d because pesticides run off into water, they are absorbed into soil , and they are left in the air , hope this helps :)
G always pairs with C...So, if there is 30% G, then there's 30% C...which is 60%...that leaves 40% A+T - and you have to split this up too - so 20% Thymine (T) and 20% Adenine (A).

The answer is commensalism.
Commensalism is a relationship between two
species in which only one of them has benefit, and the other one is not
affected.
In this relationship, frogs benefit from this relationship. They get water and shelter from the Bromeliad. The Bromeliad <span>does not gain or lose anything in the relationship, so it is not affected anyway. Thus, the relationship between frogs and the Bromeliad is an example of commensalism.</span>
