Question

question #15
a bilge pump is a device that ships use to pump excess water out when too
likewise, a clam uses a structure called a siphon to expel water after it flows
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 contractile vacuole in a cell (like in some single - celled organisms) pumps out excess water, similar to how a bilge pump on a ship expels water.
• A vesicle is mainly for transporting substances within the cell.
• A lysosome contains digestive enzymes.
• The Golgi apparatus is involved in modifying, sorting, and packaging proteins and lipids.
• Question #16:
• In a cell model made with different foods, each food piece represents an organelle. Organelles are structures within the cell that perform different activities (e.g., mitochondria for energy production, chloroplasts for photosynthesis in plant cells).
• Option A is incorrect because it's not about substances the cell consumes (the model is about cell structures).
• Option C is wrong as it's not about tissues (tissues are made of multiple cells).
• Option D is incorrect as it's not about cell - division configuration.

Answer:

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