QUESTION 4 0.07 points Save Answer Active transport compounds move from unbalanced to balanced Low to high High to low All of the above require active transport QUESTIONS 0.07 points Save Answer Crossing the plasma membrane is easy if you Negatively charged Positively charged Are small and have no charge Are macromolecules with charges QUESTION 6 0.07 points Sowe Antwer Equilibrium? concentrations are equal in two areas separated by a semipermeable membrane All these are correct Concentrations are higher inside the cell compared to the outside. Concentrations are higher outside the cell compared to the inside

Answer 1

Ans.4. Option B is the correct answer.

EXPLANATIONS:- In active transport the compounds moves from low to high concentrations or against the concentrations gredient. In active transport, energy is required.

Ans.5. Option C is the correct answer.

EXPLANATIONS:- The particles which are small and have no charges can easy pass through the plasma membrane. It is because the membrane is lipid in nature and hydrophobic and if the molecule are small and has no charge , they can pass easily.

Ans.6. Option A is the correct answer.

EXPLANATIONS:- In equilibrium, The concentration are equal in two area seprated by a semipermeable membrane. The concentration will be same on both side. So, there will be no net transport of molecules through the plasma membrane.
