During a routine cleaning of the incubators in a college laboratory, a student accidentally increased the temperature of one incubator from 37℃ to 40℃. The next day when the students checked on the cells, they found that the cells in the incubator at 40℃ grew more than those in the incubator at 37℃. The students decided to test this observation through an experiment. (a) State the hypothesis for this investigation. (b) Identify the independent and dependent variables. *

Hypothesis: If there is an increase in the temperature the number of cells increases.

The independent variable: different temperatures.

dependent variable: number of cells.

Explanation:

The hypothesis is a possible explanation for any phenomenon that occurs in nature, which is based on prior knowledge or evidence and can be tested with the help of the scientific method.

The independent variable is a variable that is subject to change and manipulated in an investigation and affects the dependent variable, in this case, different temperatures are the independent variable.

the dependent variable is the variable that depends on the independent variable and helps in finding the result and conclusion of the effect.
