B because the genotypes of the parents would be Pp because they are heterozygous. The genotypes they could inherit are PP, Pp, Pp or pp.
So that the pressure will be at constant. If the water level will have raised up in the graduated tube directly above the water level in the burets and levelling funnels, the pressure on the trapped gas is no longer at usual atmospheric pressure. It produces a tapping effect on the locked in gas therefore dropping the pressure. If the burets and levelling funnels will be dropped below water level the reverse effect is produced.
Explanation:
he main difference between Independent Variables and Dependent Variables is in the definition. Independent variables in research can be manipulated or altered to see their impact on other variables. The dependent variable is dependent on other variables. It is the variable that is measured or tested by a researcher.
