Question 1

difference between simple and facilitated diffusion..

Answer 1

Simple is used for small non charged molecules that pass through the bilayer while faciliatated is uses proteins to move large charged molecules.

Question 2

What is the differance between Hypertonic, Hypotonic, and Isotonic

Answer 2

Hypertonic: Has lots of solute and water goes toward it.
Hypotomic: Has few solute.
Isotonic: Has equal solute.

Question 3

what is Active transport.

Answer 3

When cells may need to move molecules against concentration gradient and allow any type to pass.

Question 4

Why does the volume need to be minimized while surface area is maximized.

Answer 4

The more volume a cell has the longer it will take for molecules and proteins to be transferd and not be as efficient.
