Which statement describes the ability of the cell membrane to allow various substance to move through it?

• The cell membrane is selectively permeable.

• The cell membrane is NOT selectively permeable.

Which is the correct definition of cellular homeostasis?

• A process that occurs in cells to convert chemical energy from glucose in ATP

• a process that captures light energy from the Sun and turns it into chemical energy in the form of glucose

• the process in which an organism’s internal environment is kept stable in spite of changes in the external  condition or environment.

What is the term to describe maintaining internal balance in the cell? 

• Diffusion

• Homeostasis

• Osmosis

• Active transport

What will happen to a cell if homeostasis is not maintained?

• The cell will immediately divide.

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

• The cell will eliminate wastes more efficiently.

• Cell processes will continue unchanged.
