6) Which is an example of a group of cells with a common structure and function?
a. Stomach
c. Mitochondria
b. Muscle tissue
d. Digestive system
Use the diagrams and information below
7) The diagrams below show the digestive systems of an earthworm and a bird.
Earthworms and birds have strong muscular gizzards. The gizzard grinds food into
small bits before it passes on to the intestine. Mammals, in contrast, do not have
gizzards.
Why do earthworms and birds need to have gizzards but mammals do not?
A. Earthworms and birds are not equipped to chew food.
B. Earthworms and birds eat food that is difficult to digest.
C. Earthworms and birds have intestines that work inefficiently.
D. Earthworms and birds do not have stomachs to mix moistened food.

8) The diagram below represents a cross section of a lagoon and some of its
aquatic organisms. A magnified view (400X magnification) of each organism is
shown.
Structure Z serves the same function in each of the organisms.
What is the function of structure Z in the water lily, fish and paramecium cells?
A. to move the cells
B. to control cellular activities
C. to carry out photosynthesis
D. to allow nutrients to enter and exit the cells

the others?
A. tissues
B. organs
C. cell structures
D. organ systems
10) Fungi recycle leaves in forests. Fungi release chemicals onto the leaves to break
them down into smaller particles. The fungi use the small particles for growth.
