Answer:
recessive
Explanation:
a recessive allele is the gene donated by one parent which is present within the genotype, but is not expressed in the phenotype of the person's characteristics.
The Dependant Variable is the one responding to change.
Control Variables are controlled by you, and you influence the Independent Variables.
What do you mean by following?
The guard cell is responsible for controlling the size of the stomata in leaves. These do so as a result of an interaction between potassium ions and water in and around the cells. When potassium ions accumulate inside the guard cells the water potential inside these cells is lower than that of the outside and as a result, water has to be taken in. This makes the guard cells turgid which in turn stretches them and results in the opening of the stomata. Meanwhile, when potassium ions accumulate outside the cell, the opposite scenario results. Water from inside the cell moves out, making the guard cells flaccid, thus causing these to cover (and effectively close) the stomata.
