Question
Part -Expression This is really cool. Just one gene can change how the whole plant looks" Emily glanced at the white board one more time and then hesitated: "But why do plants need to change the way they look Professor Griffin smiled and said, "Excellent question. Unlike animals, plant growth and architecture are heavily influenced by environment. The ability to adjust the degree of branching can help the plant harvest the sunlight more efficiently. Let's analyze some data to see if the tbI gene has similar functions in other plants." Questions The tbl gene has a homologue in Arabidopsis called BRC1. To test the function of this gene in Arabidopsis, a group of scientists conducted an experiment to measure the degree of branching in wild type plants and Figre 1.

The major conclusion of this experiment is the branch formation is promoted by the loss-of-function mutation of brc1 gene.
(1) The independent variable is the quqntity of the soil.
(2) The dependent variable is the number of branches in a plant. The dependent variable always depends on the independent variable.
(3) Here two types of evidences are shown one mutant plant and one wild plant. The plant growth is heavily influenced by the enviornmental factors.
(4) If the quantity of the soil changes the number of branches in the plant will also be changed. Thus dependent variable is influenced by the independent variable.
