Answer:
The correct answer is -
a. - as the distribution of the phenotype diminishes
b. -cross sunflowers exhibiting the greatest phenotypic variance
Explanation:
Artificial selection refers to the practice of breeding plants or animals for particular desired traits by consciously choosing which individuals reproduce.
-Variance indicates how individual traits differ from the average characteristics of the species or how they deviate from the mean, demonstrating the degree of measurement differences.
-If the distribution remains unchanged, variance indicates no variation. However, if the spread indicates a range change in measurements, the variance will also change.

A state of respiratory acidosis is implied, indicated by a decreased blood pH and accelerated breathing in the patient.
Common side effects from substance abuse often include symptoms such as anxiety, excessive excitement, difficulties in concentration, lack of coordination, and tremors. Drugs like cocaine, nicotine, ecstasy, and amphetamines fall under this category. However, any substance that induces a feeling of euphoria or a 'high' can potentially become addictive.
The best descriptor for the transport protein is the sodium potassium pump's function. However, none of the other alternatives are accurate. Halting the sodium potassium pump’s function is incorrect as it is the sole mechanism for moving proteins into the cell. If this action is inhibited, damage to heart and intestine cells could occur. Increasing glucose concentration outside the cell is also erroneous, as glucose generally moves out of the cell under normal conditions; correct action would be to decrease glucose concentration outside the cell to retain it inside. Lowering activation energy does not pertain to this situation, nor does increasing digestive enzyme presence.
