Answer:
C. The weight loss of the mice
Explanation:
There are two variables present in the experiment;
- The time of the day that the mice rane
- The weight lost of the mice in each time test
The time of the day varies from morning, noon to evening. This variable is independent of any other aspect.
It shall always be morning noon and evening in every single day.
The time of the day shall determine the amount of weight loss.
Each time shall vary in the amount of weight loss.
Thereby weight loss becomes our dependent variable.

Answer:
A. ability to make food and ability to swim
Explanation:
Living organisms have been grouped into an hierarchical system of classification that begins with the kingdom, which is the most inclusive taxon. Organisms were placed into kingdoms based on two major criteria namely; their nutrition and mobility.
Their nutrition depends on their ability to make food by themselves (autotrophic) or not (heterotrophic) while their mobility depends on their possession of structures for locomotion.
Answer:
The chemical composition of the side chain determines the function of the amino acids. The function of a protein depends on the sequence and the number of amino acids in it.
Explanation:
The function of an amino acid primarily depends on the different side chains present in an amino acid. These different side chains are normally referred as the "R Group".
The protein function is determined by the series of amino acids that the protein possesses. A change in any one of the amino acids will cause change in the structure of the protein. When the structure of a protein changes, it will not be able to perform its function. Hence, the structure of amino acids plays a vital role in the functions of a cell.
