Answer:

Plate has all the essential nutrients that is required by the bacteria.

Explanation:

Bacteria grows on the plate, which indicates that the plate has all the essential nutrients that is required by the bacteria. Bacteria needs a type of media for its growth which contains all the necessary items which plays a key role in its growth and development. This plate has a media that contains food which the bacteria use for its growth and development so that's why we can say that  plate has all the essential nutrients that is required by the bacteria.

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.
