The Endosymbiotic Theory states that the mitochondria and chloroplast in eukaryotic cells were once aerobic bacteria (prokaryote) that were ingested by a large anaerobic bacteria (prokaryote). This theory explains the origin of eukaryotic cells.

The survival rate is a measure of the fitness of each species. Option A is correct. Green beetles are more fit for the environment than brown beetles are.
<h3>
What is fitness?</h3>
Fitness or Aptitude can be defined as the contribution of each genotype to the next generation.
Fitness is reflected by the phenotype that results in the survival, fertility, and capability of having a mate.
It is a way of measuring the individual ability to leave fertile offspring.
Aptitude must be significant to the natural selection act in its favor.
In the exposed example we can see the survival rate of two species.
The survival rate is telling us about the fitness of each species.
- The green beetle increases its survival rate (fitness) each year
- The brown beetle decreases its survival rate each year
These results lead us to believe that the Green beetles are more fit for the environment than brown beetles are. Option A is correct.

<span>The answer would be: host symbionts with colorful photosynthetic pigments
Coral can host symbionts that will help in their growth. There are algae that could live on the coral surface, giving them some of the energy from photosynthesis and help in calcification while the coral protects the algae. </span>The symbiosis will be formed when nearby algae attach to the corals. A stress on the coral can cause the algae to eject the algae.
