Cells and Body Systems Unit Test

Q: Compare hypertonic, hypotonic, and isotonic solutions. When an environment is hypotonic, what happens to the cell?
A: The cell has more solute, so solvent moves from outside the cell to inside, causing the cell to swell.
Q: Which process is shown in the image?
A: Endocytosis.
Q: For which kind of external environment is a saltwater fish adapted?
A: Hypertonic.
Q: The genetic material of the eukaryotic cell is stored inside which organelle?
A: Nucleus.
Q: Which of the following best describes the function of the ribosomes in eukaryotic cells?
A: Decodes the sequence of based on the mRNA and then creates specific proteins.
Q: What is the unique function of central vacuoles in a plant cell?
A: They store water.
Q: Which type of cells have a high concentration of mitochondria?
A: Heart cells.
Q: Plants prefer hypotonic environments because
A: The excess water that enters the cell allows the central vacuole to maintain turgor pressure.
Q: The nervous system is responsible for
A: Receiving and processing stimuli from the body.
Q: What is the function of the esophagus?
A: Connect the mouth with the stomach.
Q: Summarize the functions of the nervous system
A: The nervous system controls the digestive system by sending signals to the stomach, telling it to contract and digest food.
Q: Which animal is often used to model human body systems?
A: Pig.
Q: Compare types of models. Which model best illustrates the formation of blood cells?
A: Computer-generated model.

  3. Atlas is almost correct. for #6 which of the following best describes the function of the ribosomes in eukaryotic cells? the answer is Decodes the sequence of bases on the mRNA and then creates specific proteins. and #9 Plants prefer hypotonic environments because the excess water that enters the cell allows the central vacuole to maintain turgor pressure.
