I think it resembles the nervous system because like the nucleus, the brain controls body functions while the nucleus controls the cell’s functions.
The correct answer is A. Flower color is a recessive trait.
The recessive gene does not show its effect in heterozygous condition according to Mendel’s law of dominance. Thus, in heterozygous condition, dominant gene determines the phenotype for a trait. In this question a plant is homozygous for flower color. This indicates that pink flower determining gene can only be expressed in homozygous condition. Therefore, flower color is a recessive trait.
Because cells need insulin for glucose from the blood if they don’t have enough glucose it can build up in the blood and that causes the tiredness. Glucose is needed to create energy otherwise you would end up tired.
