Which best explains why it is dangerous for a cell to become too large?

• it may crowd out other cells

• its volume exceeds its surface area, making transport difficult

• it will be unable to produce enough lipids for its plasma membrane

• it will require far less energy than a normal sized cell

What are adaptations of cells to increase their surface area?

• They can divide when they reach maximum size.

• The can have long branching structures.

• They can become star shaped.

• They can be thin and flat.

What is the relationship between metabolic rate and surface area to volume ratio?

• Higher surface area to volume ratio leads to higher metabolic rate

• Higher surface area to volume ratio leads to lower metabolic rate

• Lower surface area to volume ratio leads to higher metabolic rate

• Lower surface area to volume ratio leads to lower metabolic rate

What is the surface area to volume ratio of a cube with the same volume as another cube but with larger surface area?

• 2

• 5

• 4.0

• 6.0

Why do elephants have a slower metabolic rate compared to mice?

• Because elephants have a larger surface area to volume ratio

• Because elephants have a smaller surface area to volume ratio

• Because mice have a larger surface area to volume ratio

• Because mice have a smaller surface area to volume ratio

How does the shape of the desert hare's ears help with evaporative cooling?

Which of the following best explains why smaller organisms tend to have higher metabolic rates than larger organisms?

• A) Smaller organisms have a higher surface area to volume ratio, facilitating faster heat loss and nutrient exchange.

• B) Smaller organisms have a lower surface area to volume ratio, reducing heat loss and nutrient exchange.

• C) Larger organisms have a higher surface area to volume ratio, facilitating faster heat loss and nutrient exchange.

• D) Larger organisms have a lower surface area to volume ratio, reducing heat loss and nutrient exchange.
