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:
provide flexibility
Explanation:
According to my research on studies conducted by various medical professionals, I can say that based on the information provided within the question the role of elastic fibers is to provide flexibility. Elastic fibers contain elastin, a protein that acts like rubber and allows them to stretch and recoil like rubber bands, making them very flexible.

<span>According to the ipat model, technology that enhances our acquisition of minerals, fossil fuels, timber, and ocean fish increase environmental impact.
IPAT is a model or equation which expresses that
I (stands for Environmental impact) is the product of three factors: P (stands for population), A (is affluence) and T ( for Technology).
IPAT can be written as (I=PAT) or I = pxAxT</span>

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
