axesual thats how they reproduce
Answer:
D. Selection has led to decreases in the size of fish at the age of reproductive maturity.
Explanation:
The larger body size of the fishes is not an adaptive trait as it reduces the survival chances of these fishes. The process of natural selection tends to increase the frequency of the traits that increase the survival fitness of the organisms. Here, the fishes with smaller body size at the reproductive age have greater chances of survival and would reproduce more to leave more progeny. Over the generations, the selection pressure would increase the proportion of fishes that are smaller during reproductive age.
A downside to this mutant corn wohld be that it would give rise to a presticide-immune strain of the certain insect.
All the non-immune bugs would die, leaving the few immune ones to reproduce. That would result in a overpopulation of immune super-bug that would still be able to go ham on the large, GMO corn, like nothing happened, and still go on to affect native plant populations. That can become a huge problem.
Hope that helped!
Answer: Resource partitioning
Explanation:
In order to make organisms of different species (competitors) coexist, limited resources are to be divided with a ecological area.
Organisms of same species could be made to live together, so as to reduce wastage of limited resources
