Homeostasis is necessary for a cell to survive. What is the definition of homeostasis?
a) the elimination of wastes
b) the division of cells to form new cells
c) the maintenance of a stable internal environment
d) the process by which energy from the sun is used to make food
What is the result of homeostasis at the cellular level?
a) the cell dies
b) the cell divides
c) the cell no longer obtains energy
d) the environment within the cell is stable
The survival of a cell depends on the cell maintaining homeostasis. What is most likely to happen to a cell if homeostasis is not maintained?
a) The cell will immediately divide.
b) Cell processes will continue unchanged.
c) The cell will eliminate wastes more efficiently.
d) Many chemical reactions in the cell will slow down or even stop.
Cells must be able to perform certain functions in order to survive. Which of the following must all cells do to survive?

b) use oxygen
c) absorb wastes
d) continue growing
What is a way an organism helps maintain homeostasis?

Cells can die or become damaged. What cell process replaces dead or damaged cells?
a) Cells divide to make new cells.
b) Cells multiply by cellular respiration.
c) Cells take in new cells through endocytosis
d) Cells grow larger to make up for the lost cells
Some cells in multicellular organisms are constantly dividing. What is one reason why cells divide?
a) so that an organism can eliminate wastes
b) so that an organism can grow by adding new cells
c) so that an organism can obtain the energy that it needs
d) so that an organism can exchange materials with its environment
In one type of cell division, a single cell forms two new cells. This process is called mitosis. What is a reason that human skin cells frequently undergo mitosis?
a) to get energy for the body
b) to replace dead or damaged skin cells
c) to prevent bruises on the body
d) to replace dead or damaged muscle cells
Cells exchange materials with the environment around them. What is the main reason for this?
a) to replace damaged and dying cells
b) to keep the cell membrane functioning
c) to release energy into the environment
d) to get rid of wastes and take in nutrients
Organisms can respond to changes in their environment in order to maintain homeostasis. What does a tree do to maintain homeostasis during the winter months?
a) hibernates
b) loses its leaves
c) basks in the sun
d) shivers to generate heat
