SA:Volume, Risk Factors Flashcards
1
Q
What is the relationship between size and SA : Volume ratio?
A
As the size of the organisms increases the surface area to volume ratio decreases
2
Q
What’s the correlation between the SA : Volume ratio and metabolic rate?
A
- as the surface area to volume ratio decreases, metabolic rate also decreases.
3
