Answer:
For calculating the surface to volume ratio for a spherical cell,
Surface area (S) = 4πr²
Volume (V) = 4πr³ / 3
Ratio = S / V = 4πr² / 4πr³ / 3 = 3 × 4πr² / 4πr³
= 3/r
1. 15 micrometer diameter = Ratio = 3/7.5 = 0.4
2. 2 micrometer diameter = Ratio = 3/1 = 3
The cells exhibiting high surface to volume ratio shows enhanced metabolic activity. Shows easy uptake of oxygen, nutrients, water, and also the excretion of waste as they possess large surface.
Answer:
Weight
Explanation:
The weight of a body is a function of its mass and the gravitational pull on it.
W = mg
W is weight
m is mass
g is the acceleration due to gravity.
