True, this is because Darwin realised that organisms best suited to their environment are more likely to survive and reproduce, passing on their characters to their offsprings.

Answer:
It greatly affect population of fish.
Explanation:
If there were no shrimp in the close ecosystem then many fishes die due to lack f food because shrimp is the food of many small and large fishes. They also play a great role in protection of fish's skin by eating parasite, bacteria and fungi present on their skin so it also act as scavengers so if these shrimps are not present many fishes die due to various diseases and the ecosystem would be disturb.
R, S, and T always have the same percentage composition, while X, Y, and Z always have the same percentage composition. Chargaff's rule is then a viable theory that can be used in this situation.
- The DNA of any species of any organism must have a 1:1 stoichiometric ratio of the purine and pyrimidine nucleotides, according to Chargaff's principles.
- More specifically, the ratio of guanine and adenine to cytosine and thymine must be the same. This pattern is present in both the strands of the DNA.
- The formula comes as A + G = T + C = 1
- In this universe there are six base pairs R,S,T,X,Y and Z. composition of R,S and T is always same thus these can be considered the purines.
- The percentage composition of X,Y and Z is always the same thus these can be considered the pyrimidines.
- applying Chargaff's rule to these bases:
R + S + T = X + Y + Z
= 1:1
Thus, the nucleic acid will contain six base pairs where bonds are formed between RX, SY and TZ.
