Answer:
mutualistic
Explanation:
The interaction between two organisms in which both the organism gets benefitted from each other is called a mutualistic relationship. This mutualistic relationship is seen in the concept of endosymbiosis.
According to the endosymbiotic theory chloroplast and mitochondria are evolved by engulfment of different bacteria by ancestral cells. Then these bacterial remained in a mutualistic relationship with each other and the ancestral cell evolved into a eukaryotic cell.
So as mitochondria and chloroplast live with a symbiotic relationship with eukaryotic cells, therefore, it is considered as mutualistic relationship.

Answer:
controlled experiments
Explanation:
Experiments in which all variables are identical except for one are called controlled experiments. This where an observer tests his hypothesis by looking on changes that were brought about by one variable. The results are always dependent on one adjusted variable.
Answer:
The population has evolved because there was a change in allele frequencies.
Explanation:
The evolution may be defined as the process of the change of the species characteristics with the passage of the time. The natural selection, mutation and the genetic drift might cause the evolution.
The population might have evolved as the allele frequencies has changed from the generation to the generation. Although the variation among the population is quite less but the variation is still enough for the evolution of the elephant seals.
Thus, the correct answer is option (D).
Your answer should be the second one
