Some students believe that if they drink a glass of milk before bed and would make them sleep longer what’s the independent vari
miss Akunina [59]

Answer:

Independent variable: Glass of milk

Dependent variable: Time of sleep

Control variable: same type of milk

Explanation:

Independent variable in an experiment refers to the variable that the experimenter manipulates or changes in order to get a response in another variable (dependent). In this case, the independent variable is the GLASS OF MILK taken before bed.

Dependent variable is that variable that is measured in an experiment. It is the variable that responds to the changes made to the independent variable. In this experiment, the dependent variable is the TIME OF SLEEP of the students.

A control variable or constant is the variable that is kept unchanged throughout the course of the experiment in order not to alter the outcome of the experiment. In this experiment, a control variable can be the SAME TYPE OF MILK taken by each student.

Korvikt [17]

Dark fur color appears to be an adaptation for mice living in dark environments, as both the frequency of the characteristic and the allele that generates it have altered. These findings further back with the theory that selection is context-dependent, as dark mice were preferred in some contexts but not in others.

<h3>What is mutation?</h3>

A mutation is defined as a change in the sequence of genetic letters, called bases, within a molecule of DNA.

In a population, more offspring are born than can survive, resulting in competition among people. Individuals that possess a certain trait are more likely to live and/or produce more offspring than those who do not possess that trait. The context in which a species exists influences its selection. Characteristics that are advantageous in one setting may be detrimental in another.

New mutations cause black color.

  1. Fur color is controlled by many genes (4:29).
  2. Most genes are identical, but dark and light rock
  3. pocket mice differ in one gene (Mc1r; 4:55).
