question #15
a bilge pump is a device that ships use to pump excess water out when too much water enters the ship.
likewise, a clam uses a structure called a siphon to expel water after it flows over its gills. which
cellular organelle has a similar job?
a vesicle
b lysosome
c golgi apparatus
d contractile vacuole
question #16
a student builds a plant cell model by arranging different foods in a bowl.

in this cell model, what do the different pieces of food represent?
a substances that the cell consumes
b structures that perform different cell activities
c tissues that are formed by different cells
d configuration of parts during cell division

Explanation:

• Question 15:
• A bilge pump expels excess water. A contractile vacuole in a cell also expels excess water. Vesicles transport materials. Lysosomes break down waste. The Golgi apparatus modifies and packages proteins.
• Question 16:
• In a cell model, different parts (represented by food) are organelles. Organelles are structures that perform different cell activities. Substances the cell consumes would not be organized as structures. Tissues are made of cells, not parts of a single cell model. Cell - division configuration is a process, not static structures in a model.

Answer:

• Question 15: D. contractile vacuole
• Question 16: B. structures that perform different cell activities
