The Hardy-Weinberg equation was designed to show the conditions that must be met in order for no change to be seen in a population.
Describe the 5 criteria that need to be in place in order to meet the Hardy-Weinberg Equilibrum.
How are these criteria not met in nature?
If all 5 criteria are met does evolution occur?

I got a 3/5 on a quiz about the membrane or membranes and transport, but they never told me which one's i had wrong and why? Help me out please? these were the questions and my answers and my knowledge on why i answered the way i did.
What molecule gets attached to the sodium-potassium pump that leads to a conformational change?
a. GTP
b. Phospholipid
c. ATP - I said ATP because I know that the pump requires ATP to do active transport.
D. Integrin
Which of these types of cellular transport requires energy to function?
A.) Bulk Transportation (I said Bulk Trans. because I know it is a type of Active transportation and Active transportation requires energy.)
B.) Diffusion
C.) Facilitated Diffusion
D.) Osmosis
If the animal cell is placed in a solution of 25% sugar, what happens to this cell?
A.) The cell will lose sugar to the surrounding solution
B.) The cell will lose water and shrivel up (I said B, because it's not telling me how much concentration the cell has so im assuming there's less water outside due to 25% sugar so it would move out of the cell and the cell will shrivel up to reach equilibrium.
C.) The cell will not gain or lose any water because it's already at equilibrium
D.) The cell will gain water and burst
How many sodium and potassium are pumped in/out of the cell and in what direction?
A.) 2 potassium out: 2 sodium in
B.) 2 sodium out: 2 potassium in
C.) 2 potassium out: 3 sodium in ( I was watching a video about the pump and im 65% positive it was 2K+ (potassium) going out of the cell, and 3Na+ (sodium) going inside the cell)
D.) 3 sodium out: 2 potassium in
What type of solution, typically, is best for a plant cell to survive and thrive in?
A.) hypertonic
B.) isotonic ( I said isotonic because cells want to reach equilibrium so im assuming thats how they thrive)
C.) hypotonic
