Answer:

B. very high genetic variation

Explanation:

Selective breeding is the process by which crops or animals with desired phenotypic traits are chosen to produce offspring, which will contain the desired qualities. In this case, a group of scientists is trying to apply the principles of selective breeding to develop a particular crop plant.

This goal of producing a useful crop plant by the scientists can only be achieved when the plant species in question possess a HIGH GENETIC VARIATION i.e. difference in genetic constitution of individuals of the same species. This allows the individuals in the population to survive better.

Why does ethanol becomes cloudy/white when testing fat
ki77a [65]

Answer:

Ethanol is known as a fat solvent, and the cloudy or white color that it acquires when testing fat is due to the fact that this test includes the addition of water, forming an emulsion.

Explanation:

<u>The emulsion test for fats</u> is a test used to show the presence of these in some substances or foods.

Under normal conditions, fats are miscible - they can be dissolved - in ethanol, an alcohol, but not in water.

This test consists of dissolving the substance to be tested in ethanol, and then adding water. The principle by which the emulsion test is governed is that ethanol allows a certain amount of fat to dissolve in water, forming a cloudy or whitish emulsion.
