Answer and explanation;
-Protein functions are so diverse because of the many unique three-dimensional structures protein polymers form. The functions of proteins are very diverse because there are 20 different chemically distinct amino acids that form long chains, and the amino acids can be in any order. For example, proteins can function as enzymes or hormones.
-The sequence and number of amino acids ultimately determine a protein’s shape, size, and function. A change in any amino acids in the sequence alters the structure and function of a protein.
-Enzymes, which are produced by living cells, are catalysts in biochemical reactions and are usually proteins.
-Hormones are chemical signaling molecules, usually proteins or steroids, secreted by an endocrine gland or group of endocrine cells that act to control or regulate specific physiological processes, including growth, development, metabolism, and reproduction.
-Additionally, structural proteins provide internal and external support to protect and maintain cell shape.

The true statement about the mother of this family tree is that she is a carrier for color blindness.
The correct option is (B).
Color blindness is a disability in which you are unable to see colors normally. Color deficiency is another name for it.
It is a condition in which a person is unable to distinguish between different colors.
The most common colors are greens and reds, but it can also happen with blues.
This condition is only dominant in males, but females carry this disability as recessive carrier, so they can transfer this gene to the next generation.
Thus, option (B) she is a carrier for color blindness is correct.

B,
since males only need one recessive trait for it to show, and the father is not colorblind, the mother at least has to be a carrier for the colorblindness trait.
Answer: False
Surface run off is a kind of water erosion in which the surface layers of the top soil containing minerals and sediments is wiped out by the water and deposited to some other place. In the given situation, the surface run off of the farmer's field close to the stream will likely to remove the fertilizers hence,the level of the fertilizers in the stream is likely to increase.
a. True
b. False
