You water three sunflower plants with salt water. Each plant receives a different concentration of salt solution. A fourth sunflower plant receives pure water . After two weeks, the height is measured. Identify the following parts
Independent variable
Dependent variable
control

IV: salt solution

DV: Hight of plants

Control: the fourth plant

Explanation:

Independent Variable: what it's watered with (regular water or salt water as well as the concentration of salt water)

Dependent Variable: Height

Control: the type of plant (sunflower)

Explanation:

IV: what changes

DV: what's being tested

Control: what stays the same

the hardy-weinberg equation is as follows:

where is homozygous dominant, 2pq is heterozygous, and is recessive.

we also know that:

so since we know that homozygous dominant is 0.53, we can solve for p:

so then we can solve for q:

so then we can solve for the heterozygous term:

so now we know that the percentage of the population that should be heterozygous is 39.6%.
