The diagram below represents two cells, X and Y.

Which statement is correct concerning the structure labeled A?

• It aids in the removal of metabolic wastes in both cell X and cell Y.

• It is involved in cell communication in cell X, but not in cell Y.

• It prevents the absorption of CO₂ in cell X and O₂ in cell Y.

• It represents the cell wall in cell X and the cell membrane in cell Y.

The cytoplasm in a cell carries out a function similar to a function of which human system?

• Respiratory system

• Reproductive system

• Circulatory system

• Nervous system

Cellular communication is illustrated in the diagram below. Information can be sent from

• Cell A to Cell B because cell B is able to recognize signal 1

• Cell A to Cell B because cell A is able to recognize signal 2

• Cell B to cell A because cell A is able to recognize signal 1

• Cell B to cell A because cell B is able to recognize signal 2

The diagram below represents levels of organization in living things. Which term would best represent X?

• Human

• Tissue

• Stomach

• Organelle

Humans require organ systems to carry out life processes. Single-celled organisms do not have organ systems and yet they are able to carry out life processes. This is because

• Human organ systems lack the organelles found in single-celled organisms

• A human cell is more efficient than the cell of a single-celled organism

• It is not necessary for single-celled organisms to maintain homeostasis

• Organelles present in single-celled organisms act in a manner similar to organ systems

Which organelle is correctly paired with its specific function?

• Cell membrane--storage of hereditary information

• Chloroplast--transport of materials

• Ribosome--synthesis of proteins

• Vacuole--production of ATP

Two primary agents of cellular communication are

• Chemicals made by blood cells and simple sugars

• Hormones and carbohydrates

• Enzymes and starches

• Hormones and chemicals made by nerve cells
