Answer:

It is an environmental pollutant. It might disrupt sexual reproduction in marine organisms.

Explanation:

It is a pathogen. It might disrupt growth and development in marine organisms.  - false. Estrogen and similar synthetic compounds cannot be classified as a pathogen. Pathogens are microorganisms that cause disease. Estrogen is a hormone, not a pathogen.

It is an environmental pollutant. It might disrupt sexual reproduction in marine organisms.  - true. In this case, synthetic chemicals that mimic estrogen function have leaked into the <em>environment</em>, meaning it is an environmental pollutant. Because estrogen is a sex hormone that exists in all vertebrates (not just humans), its artificial existence in the environment will cause effects in marine life when exposed to it. This could interfere with sexual reproduction.

It is a genetic factor. It might be toxic to marine organisms and lead to death, changing the population structure - false. Although esrtogen can impact gene expression, it will not be considered a genetic factor. It would also unlikely be toxic to marine life, as they also possess estrogen.

It is both a pathogen and an environmental pollutant. It might lead to food shortages -  false. Estrogen cannot be classified as a pathogen.

Rhodobacter cells perform photosynthesis in the presence of light and grow heterotrophically in the dark. After being cultured i
Marrrta [24]

Answer:

Phenotypic changes:

When Rhodobacter is cultured in total darkness for multiple generations, the ability to produce it's own photopigment reduces with time with little or no ability to undergo its own photosynthesis due to absence of enzymes or pigment for photosynthesis.

It becomes expensive for the Rhodobacter to undergo photosynthesis. This allows mutants that can grow in the dark to take over from the culture grown in the dark.

Evolutionary processes:

It's natural selection that allows the fittest organism to survive. As in the case of the mutants
