Diatoms contain chloroplasts that have four membranes. These four membranes are evidence of secondary endosymbiosis (Option c).
<h3>What is secondary endosymbiosis?</h3>
Secondary endosymbiosis is a hypothesis used to explain why diatom chloroplasts have four membranes.
According to this hypothesis, diatoms received different genes from distinct photosynthetic and non-photosynthetic ancestors.
The acquisition of genes of different ancestors led to diatoms having chloroplasts with four membranes.

Answer:
Biology can simply be described as the study of living organisms. Biology is divided into many sub categories depending on the features of life that we want to study. For example, molecular biology is the study of molecules which make up living organisms.
Zoology can be described as a branch of biology under which animals are studied. The field of zoology involved studying the taxonomy of animals, their evolutionary histories, physiology, embryology etc. All these studies are parts of biology hence zoology and biology are related.
Apart from these other unifying principles shared between zoology and biology are genetics, cell biology, population biology,biochemistry etc.
