what can you conclude bout the relationship between surface area and volume as a cell gets larger?

i need help on this question too!!!

Let’s say there are two different gases diffusing through an air filled chamber, what would be the best explanation
why these gases moved?
a) they moved from a high concentration to a lower concentration.
b) they moved from a low concentration to a higher concentration.
c) they moved due to the attraction for the other gas.
d) both gases were negatively charged.
e) pressure at either end of the glass tube cause the movement.

1) imagine, that you have series of spheres with increasing radius (simulating growing cell). what is the relation between surface and volume? Or more easily, how will you calculate them? On what are they dependent (the index at radius)?

Cis or trans? That's what matters.

The relationship between the surface area and the volume as a cell gets larger is that they both increase.

If gases are diffusing they are moving from high concentration to a lower concentration. A
