The independent variable of an experiment is the one that is intentionally changed or manipulated to see the results of changing said variable.
We are told that in each different group, the amount of caffeine that is given to the dogs changes - in the control group, they get no caffeine, in the 2nd group, they get 10 mg of caffeine each, and in the 3rd group, they get 50 mg of caffeine each.
Therefore, since the amount of caffeine that is given to the dogs is the only variable that is being manipulated, this is the independent variable.

Answer:
The rock pocket mice rely on their fur color for camouflage. So, on the tan sand more light colored mice will survive because they blend in and on the dark lava rock more dark colored mice will survive and the allele for dark fur will be passed on to their offspring
Answer:
Red light act as a inhibitor and hence causes delay in flowering
Explanation:
Through Periodism phenomenon, the regulation in exposure to daylight for a certain time period can delay or enhance the flowering of the "light duration"sensitive plant.
When "short day plants" are exposed to light between the essential long period of nights or dark period, the stage of flowering gets delayed.
Hence, chrysanthemums on being exposed to red light during their daily darkness period lead delay in flowering as red light act as an inhibitor.
