Human heart cells require a constant release of energy to function continuously. Which structure would be numerous in such cells to meet this demand?

• nuclei
• mitochondria

Which statement describes ALL prokaryotic and eukaryotic cells?

• Ribosomes are present in the cytoplasm.
• Materials are stored in vacuoles.

Which of the following statements identifies the cell below?

• This is a plant cell because it contains mitochondria.
• This is an animal cell because it contains mitochondria.
• This is a plant cell because it contains a cell wall.
• This is an animal cell because it contains a cell wall.

Unicellular organisms, such as bacteria, and many protists, can survive as one cell in their environment, while a cell from a multicellular organism (such as you skin or liver cell), could not survive without the other cells in your body. Which term refers to why this is the case?

• Cell specialization

• Endosymbiosis

• photosynthesis

• None of the above

• It is impossible to tell

The image below shows how Eukaryotes most likely evolved to contain chloroplasts, and mitochondria. What is the name of the process?

• A. Cell specialization
• D. Endosymbiosis

Which statement correctly describes cells produced through asexual reproduction?

• They do not contain genetic material.

Which process can be a source of genetic variation?

• copying of chromosomes
• crossing over

Which phase of mitosis is shown in the picture below?

• metaphase
• prophase
• anaphase

Which statement describes the products of meiosis I and meiosis II?

• Meiosis I produces four diploid cells, and meiosis II produces four haploid cells.
• Meiosis I produces two diploid cells, and meiosis II produces four haploid cells.

Which statement correctly compares the roles of different types of organic molecules in the body?

• Nucleic acids provide support and structure for the body, while carbohydrates provide insulation.
• Lipids provide long-term energy storage for the body, while carbohydrates provide quickly available energy.
• Proteins provide cushioning for organs, while lipids carry the body’s genetic information.
