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.

Why would a diverse community be more resistant to disease, predation, and invasion
Shtirlitz [24]

Answer and explanation;

-A diverse community would be more resistant to disease, predation, and invasion because it would be a bigger diversity of genes, which means that the chance of disease would be more likely to spread in a different area than in a diverse population.

-Diversity is expected to increase the resilience of ecosystems. A diverse community would be more resistant to disease because of simple biology. The more sources for possible resistance the better the heterogeneous pool will be at resisting disease.

-High diversity strengthens a community and prevents invasion of the introduced predator. After a gradual loss of native species, the introduced predator can escape control and the system collapses into a contrasting, invaded, low-diversity state.
