Rods identifies the part of the human vision system that is part of the retina. The correct option is b.
<h3>What are rods?</h3>
Rods are photoreceptor cells found in the retina. They are photosensitive and contribute to our ability to see well in low light.
They are focused in the retina's outer regions and provide us with field of vision. Rods are 500 to 1,000 times more light perceptive than cones.
Regardless of the fact that cone-mediated eyesight dominates perception in typical daytime light levels, the overall number of rods in the human retina far outnumbers the number of cones.
Thus, the correct option is b.

Answer: A protein domain is a region of the protein's polypeptide chain that is self-stabilizing and that folds
independently from the rest. Each domain forms a compact folded three-dimensional structure. Many proteins consist of several domains.
One domain may appear in a variety of different proteins. Molecular evolution uses domains as building blocks and these may be recombined in different arrangements to create proteins with different functions.
In general, domains vary in length from between about 50 amino acids up to 250 amino acids in length.
The shortest domains, such as zinc fingers, are stabilized by metal ions or disulfide bridges. Domains often form functional units, such as the calcium binding EF-hand domain of calmodulin.
Because they are independently stable, domains can be "swapped" by genetic engineering between one protein and another to make chimeric proteins.
Answer:
The answer is A
Explanation:
Took the test and got it right.
<span>The polymer that provides plants with their genetic traits is nucleic
acid. The answer is C. Nucleic acids are what made the DNA (deoxyribonucleic
acid). The DNA are composed of a nitrogenous base, phosphate and a sugar
(deoxyribose). The bases are adenosine, tyrosine, uracil and guanine. And they
are needed to be matched to carry the trait. The nitrogenous base is the traits that
contains the genetic material and are mostly composed of nucleic acids. </span>
