Organisms used to be classified in the earliest times according to their size. As science progressed, they started getting organized by their physical traits and now they're organized by traits found in their species that are not found in others based on the theory of evolution. They are classified according to how they developed from a starting organism.

Concentration of NAD+ (umol/L) 4 8 12 16 20 Concentration of Lactic Acid (mmol/L) OHHHHHHHHHHHHHHHHHHHH 4 8 12 16 20 Time (weeks) Figure 2. The concentration of NAD* (top) and lactic acid (bottom) in the blood of a representative treated individual (a) Describe the pattern of inheritance that is most likely associated with a mutation in the MT-ND5 gene. Explain why individuals are not typically heterozygous with respect to mitochondrial genes. (b) Identify a dependent variable measured in the researcher's experiment. Identify one control that the researcher could use to improve the validity of the experiment. Justify the researcher analyzing blood samples at many intermediate time points instead of at only the beginning and the end of the 20-week period. (c) Describe the relationship between the concentration of NAD in the blood and the concentration of lactic acid in the blood during the first 5 weeks of treatment with the vitamin. Based on Figure 2, calculate the average rate of change in blood NAD concentrations from week 5 to week 17. (d) The researcher performed a follow-up experiment to measure the rate of oxygen consumption by muscle and brain cells. Predict the effect of the MT-ND5 mutation on the rate of oxygen consumption in muscleand brain cells. Justify your prediction. The researcher had hypothesized that the addition of the vitamin that is similar in structure to NADH would increase the activity of the mutated NADH dehydrogenase enzyme in individuals
Answer:
D. It provides a way to increase the
frequency of beneficial traits in a
population.
Explanation:
Artificial selection is a selection made by the human intervention. Artificial selection is better than natural selection because in natural selection organisms mate naturally with each other while in artificial selection, human selects good traits organisms to mate with each other and produce offspring which has better characteristics than parents.
Ok, so a hypothesis is an educated guess. When conducting an experiment, scientists test their hypothesis. And if their hypothesis is correct, it becomes a theory.

Answer:
Your heart has four valves that keep blood flowing in the correct direction. In some cases, one or more of the valves don't open or close properly. This can cause the blood flow through your heart to your body to be disrupted
