Answer 2

Answer:

Answer:

The difference between an independent variable and a dependent variable in an experiment is that the independent variable is the one that the researcher will change or alter in order to test the effects of the change on the dependent variable. The purpose of the experiment is to observe the relationship between changes in the independent variable and changes in the dependent variable. If the dependent variable changes as a result of the changes in the independent variable then the researcher knows that the two variable has a relationship.

Answer:Read the excerpt from chapter 7 of Night.

We all got up. We all pulled our soaked blankets tighter around our shoulders. And we tried to take a few steps, to shuffle back and forth, in place.

Suddenly, a cry rose in the wagon, the cry of a wounded animal. Someone had just died.

Others, close to death, imitated his cry. And their cries seemed to come from beyond the grave. Soon everybody was crying. Groaning. Moaning. Cries of distress hurled into the wind and the snow.

The lament spread from wagon to wagon. It was contagious. And now hundreds of cries rose at once. The death rattle of an entire convoy with the end approaching. All boundaries had been crossed. Nobody had any strength left. And the night seemed endless.

Which sentence from the passage best supports the author’s viewpoint that the situation is hopeless?

“We all pulled our soaked blankets tighter around our shoulders.”

“The lament spread from wagon to wagon.”

“It was contagious.”

“The death rattle of an entire convoy with the end approaching.”

Why are marriages between blood relatives prohibited in the united states and other countries?

Answers

Marriages or any form of sexual relations between blood relatives is incest and is completely prohibited in the United States and most other countries of the world.

There are two reasons for this:
