Answer: Option B
Explanation: First we should understand the role of enzyme and acid here. Pepsin is an enzyme which will break down proteins into simple monomers (like amino acids). And, acid causes digestion which means it will break down the protein into its respective elements and compounds. Water will act as a control in this experiment.
Option B is correct because it has all three criteria- 1. Control [water + protein] 2. With enzyme [egg white + pepsin] 3. With acid and enzyme
So this will give us an idea whether pepsin alone is breaking down the protein or digesting it. And there would be difference in test tube B and C. So this will clear the difference.
Option A is incorrect because it has not mentioned any different test tube for checking what happened with the protein. And, Option C is incorrect because mass of egg white will remain same after digestion also.
Answer:
Sea urchins have a unique relationship of oxygen and carbon-di-oxide.
Explanation:
Sea Urchins spread oxygen in a unique way. They take in oxygen by staying inside water. Oxygen enters the body through their gills and tubed feet. CO2, which is waste is released through the anus. They get oxygen only through diffusion, i.e. diffusion of oxygen into the organism. Oxygen diffuses in body through the canals and carbon dioxide diffuses back into the canals. Urchins also have the capability to cope up with rising CO2 levels in the sea.
The red-green color blindness is a recessive X-linked trait. The females are not affected unless both the X chromosomes have the affected allele. Mostly, the females are the carriers, and the males are affected as they have only one X chromosome. In the given pedigree, the father of Irene have the normal allele, while her mother is a carrier. However, Irene is neither a carrier nor affected. This means that she carries normal alleles on both X chromosomes. Hence, her allele combination is

I'm guessing there was answer choices to this problem? regardless I think I know the answer to it. Plant populations would benefit the most of the presence of decomposers due to the fact that decomposers release nutrients into the soil when they break down things.<span />
Both organs are made up if several kinds of tissues. :D
