Base your answer to the following question on the diagrams below and on your knowledge of biology. The diagrams represent some of the systems that make up the human body. A similarity between these systems is that they all

• are made of cells that are identical in structure and function

• contain organs that work independently from other organs in that system

• work together to maintain a stable internal environment

• are separate and do not interact with other body systems

Which statement correctly describes the effect on the mass of one of the cubes after the 20-minute period?

• In distilled water, the mass of the potato cube increased due to salt leaving the cells of the potato.

• In distilled water, the mass of the potato cube increased due to water moving into the cells from high concentration to low concentration.

• In the concentrated salt solution, the mass of the potato cube increased due to salt moving into the cells from low concentration to high concentration.

• In the concentrated salt solution, the mass of the potato cube remained the same due to the cell wall preventing the movement of molecules into or out of the cells.

The diagram below illustrates the movement of glucose across a cell membrane. Which two processes are most directly represented in this diagram?

• A. ATP synthesis and the diffusion of water

• B. molecule transport and energy use

• C. homeostasis and ATP synthesis

• D. homeostasis and the diffusion of water

Which molecules are normally found in single-celled organisms?

• organic molecules, only

• inorganic molecules, only

• both organic and inorganic molecules

• neither organic nor inorganic molecules

An ameba is a single-celled organism. It uses its cell membrane to obtain food from its environment, digests the food with the help of organelles called lysosomes, and uses other organelles to process the digested food. From this, we can best infer that

• all single-celled organisms have lysosomes to digest food

• amebas are capable of digesting any type of food molecule

• single-celled organisms are as complex as multicellular organisms

• structures in amebas have functions similar to organs in multicellular organisms
