In your paragraphs, you are to describe in detail the reason we have day and night, and you are also to describe in detail why we have each season. So... in your paragraphs, you should thoroughly explain the factors that cause us to have day and night. You should also describe EACH season. What factors cause us to have spring? Summer? Winter? Fall? The model that you create should demonstrate each of these things, too, and should clearly show the reason we have day and night, and the reason we have each season.

Your written explanation should include information about how the earth's rotation on its axis causes day and night.

Your explanation of each season should include information about how the tilt of the earth on its axis, the amount of direct or indirect sunlight we receive, and earth's position as it revolves around the sun, causes each season. Your written explanation of these things needs to be specific and thorough.

Which of the following best explains how viruses cause disease?
A. The virus particles ingest cells in order to
disrupt their processes. Ingesting cells allows viruses to continue to replicate.
В.
The virus particles digest parts of the host cell mechanism to create more viruses. The cell is left without means to replicate
С
The virus particles infect host cells and use the host cell's machinery to create more viruses. This disrupts the host cell's processes.
D
The virus particles invade host cells and use the host cell's machinery to create many more host cells. This causes overproduction of cells
