What do the results of the agar blocks indicate about the relationship between cell size and diffusion rate

Biology

Answer:

Knowledge of the relationship between the size (volume) of cells and their surface area helps explain the process of diffusion. Agar blocks and cells with the largest surface area to volume ratio (the smaller cubes) have the highest diffusion rates.

Explanation:

Answer:

the surface-area-to-volume ratio decreases.

Explanation:

As the cube size increases, the surface-area-to-volume ratio decreases. The vinegar can only enter the cube through its surface, so as that ratio decreases, the time it takes for diffusion to occur throughout the whole volume increases significantly.

In a study of proteins mediating cell membrane transport, microbiologists measure current versus time through the cell membranes
MrRa [10]

Answer:

Q(0) = 0C, Q(1) = 264nC, Q(2) = 952C Q(3) = 2088nC, Q(4) = 3696C Q(5) = 5800nC

Explanation:

I = 4t³ + 200t² + 60t

But charge of an object =》 Q = IT

Charge of an object is the product of the current and the time in which the current passes through the membrane.

When t = 0

Q = 4(0)³ + 200(0)² + 60(0) = 0C

When t = 1

Q = 4(1)³ + 200(1)² + 60(1) = 264nC

When t = 2

Q = 4(2)³ + 200(2)² + 60(2) = 952nC

When t= 3

Q = 4(3)³ + 200(3)² + 60(3) = 2088nC

When t= 4

Q = 4(4)³ + 200(4)² + 60(4) = 3696nC

When t = 5

Q = 4(5)³ + 200(5)² + 60(5) = 5800nC
