Answer:
An independent variable
Explanation:
An experiment consists of two variables viz: independent and dependent variable. Independent variable is the variable that the experimenter controls in order to influence or effect a change in the measurable variable called dependent variable. As the name suggests, the dependent variable is dependent on the independent variable.
For example, a scientist is trying to conduct an experiment on how the caffeine level in different types of drink affects the time of sleep in individuals. The independent variable in this experiment is the TYPE OF DRINKS because it is the variable controlled by the experimenter in order to influence the time of sleep (measurable outcome).

Answer:
RNA molecules are made of nucleotides. (Ans. C)
Explanation:
RNA, which is also known as ribonucleic acid is found in cytoplasm of the cell, and synthesized in the nucleus. It is shorter, and a single stranded molecule. It is composed of one or more nucleotides which are linked together by phosphodiester bonds.
In RNA, the ribonucleotide contains pentose sugar ribose, four nitrogenous bases (A,U,C,G), and a phosphate group. RNA plays many types of role in cells, but mainly involved in the translation process, and it's regulation which is known as protein synthesis.
