velikii [3]

Answer:

(a).concentrated lactic acid and that of NAD+.

(b).use of the response of NAD+ and lactic acid in absence of vitamin treatment as the CONTROL.

Explanation:

To understand this question and be able to solve this question efficiently we have to understand the concept of "respiration''. But, the short and the most simple answer to the question above can be found in the first statement of the question.

The electron transport chain include the cycle that occurs during glycolysis, fermentation and the transformation of NAD+ to form NADH and vice versa.

In the research, the dependent variable is the concentrated lactic acid and that of NAD+.

In order to increase the validity of the experiment, the Researcher can make use of the response of NAD+ and lactic acid in absence of vitamin treatment as the CONTROL.

In many animals, height is an example of a polygenic trait. Which types of natural selection can affect polygenic traits? I. dir
Marat540 [252]

The question is incomplete as it does not have the options which are:

I. only

I. and II. only

II. and III. only

I, II, and III.

Answer:

I, II, and III.

Explanation:

The mechanism of natural selection can be explained for the trait which is determined by one gene but the traits which can be determined by more than one gene like height (polygenic trait), the selection becomes very complex.

The natural selection can be explained by the phenotype produced in a population and that depends on the genes.  The polygenic trait shows the variation in the population, therefore, it is impossible to predict only one mechanism and therefore all types of natural selection occurs on a population.

Thus,  I, II, and III are correct.
