Surface Area to Volume Ratio

Question 1

The surface area refers to the

Answer 1

the total area of the organism that is exposed to the external environment

Question 2

The volume refers to the

Answer 2

total internal volume of the organism (total amount of space inside the organism)

Question 3

As the surface area and volume of an organism increase (and therefore the overall ‘size’ of the organism increases), the surface area : volume ratio

Answer 3

decreases

Question 4

As the surface area and volume of an organism increase (and therefore the overall ‘size’ of the organism increases), the surface area : volume ratio decreases
This is because

Answer 4

volume increases much more rapidly than surface area as size increases

Question 5

Ficks law shows relationship with variables that affect diffusion what is the formula

Answer 5

rate of diffusion is proportional to surface area x conc gradient / thickness of membrane

Question 6

Standard deviation meaning

Answer 6

Variation of values around the mean

Question 7

What does a larger standard deviation mean

Answer 7

Larger variation in data results may infer inaccurate data as if standard deviation overlaps with two data points it says that the changing of variable two values could be the same
