Answer:
C) Interaction increases the survival and reproductive rates of mutualistic species.
Explanation:
A) Mutualism offer more biodiversity to a community.
Biodiversity is the different species living in one environment. Since mutualism is only involving two species, it wouldn't increase the biodiversity of one ecosystem, making it incorrect.
B) Individuals partaking in a mutualistic relationship relationship are more resistant to parasites.
Mutualism is only benefiting two species, not their immunity to diseases and parasites. These two have no correlation with each other, making it incorrect.
D) Mutualistic interaction lessens competition in communities where it is present.
Since mutualism is only benefiting two species, they have no correlation since the relationship doesn't affect the different species in the environment.
E) Mutualistic relationships allow organisms to synthesize and use energy more efficiently.
Although there could be some relationships involving energy transfer between the species, that would sound more like commensalism or even paratsitism if you think about it. However, it is very uncommon and usually energy has no relationship with species relationships, making it incorrect.
Hope this helps! My deepest apologies if I got in incorrect!
The best answer is B.
The endosymbiotic theory states that mitochondria and chloroplasts have striking similarities to bacterial cells:
1. they have their own DNA, which is separate from the DNA found in the nucleus of the cell.
2. Both organelles use their DNA for to produce many proteins and enzymes required for function.
3. They are both surrounded by a double membrane.
4. They reproduce just the way bacteria do, replicating their own DNA and directing their own division.
In the lac operon, glucose also plays an important role along with lactose. When Lactose is present in the environment along with glucose then it cannot deactivate the regulator gene [repressor], as a result, the repressor will bind to the operator and the transcription will be blocked.
When Lactose is present in the environment without glucose then the Catabolite repressor protein will bind to the CAP Site, and lactose will bind to the repressor [regulatory gene product], as a result, the repressor gets deactivated and the transcription takes place.
Lac operon: It is a set of three structural genes z, y, and a which are all transcribed and regulated under one single promoter. The three genes code for β-galactosidase, lactose permease, and transacetylase respectively.
β-galactosidase is responsible for breaking the lactose into glucose and galactose, lactose permease is responsible for transporting lactose across the cell membrane and transacetylase attaches a particular chemical group to target molecules.

ADH increases the permeability of the collecting duct to water, and this means water flows from the Collecting duct into the blood to decrease the volume of the fluid in the collecting duct.
ADH is a hormone that increases permeability to water in the collecting ducts and therefore increases water reabsorption from the urine. This decreases the volume of water in the urine.
ADH travels in the bloodstream to its target organ, the kidneys. It causes the kidney tubules to become more permeable . This means more water can leave the kidney tubule to be reabsorbed back into the blood during selective reabsorption.
