Someone please help I need it know the first question has 2 answers

Explanation:

20J is the right answer.

force × distance = work a and b

10×2=20 c

(a) Requires the presence of an integral membrane protein -F

(b) Solutes move down their free energy gradient in the direction of thermodynamic equilibrium - N

(c) Is not subject to saturation - N

(d) Requires the hydrolysis of

ATP - A except secondary active transport

(e) Is a way of establishing a difference in the concentration gradient of solutes across a membrane - D

(f) Applies only to small, nonpolar solutes - D

(g) Applies only to ions - A

(h) Transport can occur in either direction across the membrane, depending on the prevailing concentration gradient - D

(i) Has a positive G(Gradient) - D

(j) Usually has intrinsic directionality

Explanation:

Simple Diffusion is the movement of solutes from a region of higher concentration to a region of lower concentration through a semipermeable membrane.

When then is through a transmenbrane integral protein, it is a facilitated diffusion

Active transport uses chemicals (e.g ATP) to move ions against the concentration gradient (Lower to Higher concentration).

They are two types(Primary and Secondary Active transport). Secondary active transport do not require ATP
