The diagram shows the two main parts of the body’s central nervous system. According to the diagram, which statement best describes the brain?

• It is made up of several types of tissue.

• It is made up of several types of organs.

• It is made up of identical cells that work together.

The survival of cells depends on maintaining homeostasis. What will happen to a cell if homeostasis is not maintained?

• The cell will immediately divide.

• Cell processes will continue unchanged

• The cell will eliminate wastes more efficiently.

• Many chemical reactions in the cell will slow down or even stop.

The following diagram shows two types of cells, prokaryotic and eukaryotic. Which statement correctly identifies the eukaryotic cell and then explains how to identify the eukaryotic cell?

• cell B, because there is DNA in its cytoplasm

• cell A, because there is cytoplasm filling the cell

• cell A, because there is a cell membrane around the cell
