That would be C. The control group is the group where no variable has been changed for it and it’s how something normally would be.

For example if we’re experimenting the effect of excess water on plant growth the plant getting normal amount of water is the control group and the plant getting excess water is the test group(or groups in most cases there is more than one).

You can use the growth of the control plant as a reference of how the growth of the other plant has been affected(wether it has been increased or decreased or stayed the same)

Producers make up more biomass than primary consumers because _____.
Katyanochek1 [597]

The correct answer is option a. only 10 percent of the energy at each trophic level is passed on to the next level.

The producers obtain their energy from the sunlight and convert it into usable form of energy for consumers. The primary consumers eat the plants, and obtain energy from the plants. On each trophic level, only 10 % energy is transferred to the succeeding one.

As only 10% of the energy is transferred to the next trophic level, the primary producers need to eat more plants in order to meet their energy requirement. This insufficiency of the energy transfer from one trophic level to another causes the decrease in the biomass on next level.

A inheritance pattern that is characterized by pattern in which the one allele is not completely dominant over the its recessive variant of the allele and due to its incomplete dominance a third phenotype expressed over, termed as the incomplete dominance.

In the case of the familial hypercholesterlemia, it is genetic disorder in which the individual lacks the receptors on liver cells remove cholesterol from the blood. This condition occur in the homozygous allele case. In normal people have receptors normal while in heterozygous condition individual have half of the total receptors.

Thus, it is the case of incomplete dominance.
