Carbon is transfered by plants and animals.
The conversion of one form of energy into another, or the movement of energy from one place to another. Solar panels allow for energy transfer from light energy to heat and electrical energy.
These three groups are monotremes, marsupials, and the largest group, placental mammals.
Answer:
intensity with which the rats pressed the lever
Explanation:
In research, there are two main variables which are <u>dependent</u> or <u>independent</u>.
Independent variables are controlled or manipulated by the experimenter and the independent variable in this experiment is the amount of light exposure.
The response or outcome, which is then measured is the dependent variable. In this experiment, the dependent variable is the intensity with which the rats pressed the lever with varying exposure to light.
In summary, the independent variable has a causal effect on the dependent variable so in this experiment the amount of light exposure has a casual effect on whether the rats would press a lever more.
