Muscle cells require more energy, so they more mitochondria to conduct cellular respiration.

Answer

Muscle cells require more food, so they need more mitochondria to conduct photosynthesis.

Answer

Muscle cells move more, so they need more mitochondria to allow osmosis.

Answer

Muscle cells are larger, so they need more mitochondria to allow diffusion.

Question 15

15. Mike is trying to explain how cell membranes help to maintain homeostasis in the cells of ALL living things. Which of the following facts about cell membranes BEST support his explanation? (Select three.)

Accepted Answer

Cell membranes are found in both prokaryotes and eukaryotes.

Accepted Answer

The cell membrane controls what enters and leaves the cell.

Accepted Answer

The cell membranes has transport proteins that help large molecules enter the cell.

Answer

The cell membrane is made of proteins.

Question 16

16. All of the statements below are true, and several explain differences between active and passive transport. Which statement BEST explains the DIFFERENCE between active transport and passive transport.

Accepted Answer

Active transport requires a cell to use ATP energy to move particles through the cell membrane. Passive transport does not.

Answer

Endocytosis and exocytosis are examples of active transport, and osmosis and diffusion are examples of passive transport.

Answer

Both active transport and passive transport can be used to move materials from areas of high concentration to areas of low concentration.

Answer

Active transport can use transport proteins to move materials into the cell. Passive transport can use transport proteins to move materials out of the cell.

Accepted Answer

The taiga is a large forest full of trees that conduct photosynthesis. Oxygen is produced by photosynthesis.

Answer

There are fewer organisms on the taiga than there are in other ecosystems. Therefore, these organisms use less oxygen.

Answer

There are more organisms on Earth's surface than we can count. As these organisms conduct cellular respiration, they release oxygen.
