Two species of grasshoppers live in the same area. They both feed on plants, but the presence of one species does not affect either the survival or the reproduction of the other. What type of competition is this?

A. This is not an example of competition.
B. Interference
C. Asymmetrical
D. Exploitative

Option A, This is not an example of competition.

Explanation:

Competition between two species occur when they strive for the same limited resources in a given habitat Or when they compete to attract the opposite gender mate for reproduction. Competition can be between two organisms of the same or different species.  

In this case, the two grasshopper species are not competing at all. If they would have competed, then the  survival of one species would have been definitely affected by the presence of other species.  

Hence, option A is correct

ur answer is e & d

explanation:

during the process of dna replication, brdu can replace thymidine and incorporate into the newly synthesized dna, cell proliferation thus can be reflected in the extent of brdu incorporation.
