Multiple Choice

How does large, deforested, areas affect the environment?

• they will have little to no effect on the level of biodiversity

• it will cause organisms to go extinct

• they will encourage organisms to migrate from one area to another

When does DNA replication happen during the cell cycle? Be as specific as possible.

Multiple Choice

Interphase has 3 stages; G1, S, and G2.  What happens during synthesis?

• Cells grow and carry out normal functions
• Cells copy organelles and prepare for a critical checkpoint
• The cell splits into two new daughter cells
• The cell makes a copy of its DNA

Multiple Select

Multiple Choice

A process in which DNA has the unique ability to make an exact copy of itself.

• Replication

Multiple Choice

Replication is called semi-conservative because

• Each new molecule contains part of the original DNA

• sometimes it conserves fuel

• DNA conserves ecosystems

Multiple Choice
