Answer:
C. Characters with little genetic variation will constrain the rate of natural selection
Explanation:
Natural selection can have an effect only as long as there are variations on characters on which it can select upon. Genetic variation is independent of the environment or the needs that a species may have to become better adapted to its changing environment. In other words, genetic mutations are the raw material on which natural selection can work. If there is a low rate for mutations to occur, then natural selection will proceed at a slow pace. The opposite is also true. Since mutation rate may be more frequent at some locations in a gene than at others, it can be predicted that the characters coded in that gene location will be more likely to be affected by natural selection and therefore what phenotype may be molded by natural selection.
Answer:
Antioxidants help cells perform their functions against something called free radicals. Free radicals are molecules that happen to be produced when your body breaks down food and/or when you inhale or are exposed to tobacco products. These molecules play a role in leading to diseases such as; Heart disease and cancer. When plants synthesize, they collect many non-enzymatic Antioxidants like ascorbic acid and phenolic. Since plants have many more sites of ROS generation, Therefore, they could evolve more efficient non-enzymatic Antioxidant systems than humans because of their high intake and exposure to oxygen. (answer yourself about the structure in your own words using the information I gave you). Diet relates to both the function, structure and health of your cells. Having a balanced diet helps your cells to happily work and produce energy for your daily use. A balanced diet supplies your body with nutrients so it can work effectively. Without balanced nutrition, your body is way more prone to disease, fatigue, low performance and infections.

Doubtlessly the germination rate of the radish seeds is more noteworthy when the pH is more unbiased, similar to when putting in water. There wasn't any distinction in the development of the radish seeds between the soluble and acidic arrangements in my analysis. The seeds did not develop in either arrangement. The radish seeds appeared to endeavor to develop in the acidic arrangement. The reason I say endeavored to develop is on account of you could see greenish spots where the seeds were put. The radish seeds had no adjustment in the antacid arrangement. Neither one of the solutions is a decent situation for radish seeds to develop.
Answer:
strengths:The cell model shows all the process involved, and it's easy to understand, even if a person isn't familiar with the process
weaknesses: it doesnt show organelle or rna

Explanation:
<em>If a symbol is fully filled in a human pedigree, it means that the individual represented by the symbol is affected by the trait whose inheritance is being illustrated by the pedigree.</em>
The human pedigree generally represents a symbolic illustration of how a particular trait is inherited across generations in a particular family. It shows the relationship between the members of a family and how the trait is passed down each generation either in a silent or expressive form.
Individuals within a human pedigree are represented with symbols and <u>those affected by the trait in question are completely shaded</u>. <u>Those carrying the trait in silent form are half-shaded while those that do not have traces of the trait at all are left completely unshaded.</u>
