In an experiment, the weight that mice gain is the dependent variable and the temperature of the environment is the independent variable. what must be held constant to obtain valid experimental results? a. the weight of the mice b. the color of the mouse cages c. the length of time that the mice are observed d. the temperature of the laboratory rooms

In the experiment, the weight that mice gain in different environment is analyzed. So, the weight of the mice is a variable that changes depending on the circumstances. Option A is eliminated. The color of the mouse cages is irrelevant to the experiment, because it has no impact on the weight that mice gain. Option B is eliminated. The length of time that the mice are observed must be constant for all experiments in order to obtain valid experimental results. All experiments should be done in the same period of time under different conditions. The temperature of the laboratory room is independent variable. This means that the weight that mice gain can depend on this variable. So, changing the temperature maybe will lead to different weight gain of the mice.

both graphs increase on their domain

neither graph has a y-intercept

step-by-step explanation:

the following points can be visualized easily from the graph

there is a hike in both the graphs so the graphs are increasing on their domain.x-intercept of log x and log 6x are differentthere is a vertical asymptote of both the graphs so there is no y-interceptas both the graphs are increasing so there is no horizontal asymptote
