How does the cell wall protect a plant cell?
The cell wall protects the cell by providing support and maintaining the cell's shape.
The cell wall protects the cell by storing food so the plant doesn't run out.
The cell wall is thin and flexible, which allows the cell to be moved without harming the organelles.
The cell wall is on the inside of the cell and serves to contain the contents of the cell.

Mitosis is important because it allows
new cells to replace old damaged cells.
new cells to repair old damaged cells.
old cells to self-repair when they become damaged.
existing cells to take over the function of damaged cells.

The first strands of DNA were observed through which microscope?
tunneling microscope
simple microscope
compound light microscope
electron microscope

Answer 1

1) Anaphase — chromatids separate and are pulled to opposite ends.
2) The cell wall protects the cell by providing support and maintaining the cell's shape.
3) new cells to replace old damaged cells.
4) O– — A– can receive Rh-negative O blood.
5) electron microscope — DNA strands were first visualized with electron microscopy.
