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:
A surface wave is a wave that moves along the interface of two different materials, like air and water.
Explanation:
Poor blood circulation will likely reduce the contraction power of a person's myosin.
<span>Myosins are motor proteins and they play a major role in muscle contraction and in a wide range of other motility processes in eukaryotes.
They depend on the ATP and are also responsible for actin-based motility.
</span>They are also used to produce <span>mechanical energy that is </span>used in various body<span> functions such as muscle movement and contraction.</span>
