Answer: ONLY CERTAIN SUBSTANCES CAN PASS THROUGH IT
Explanation:
1 only gases and water can pass through it.
2 substances need permission to pass through it.
3 only certain substances can pass through it.
4 substances need carrier molecules to pass through it.
5 ATP is always needed to move molecules across the plasma membrane.
B- respiration or A- transport
Resultant force = mass × acceleration, therefore acceleration = resultant force ÷ mass
Resultant force = 19 - 1.7 = 17.3 N
acceleration = 17.3÷2= 8.65 ms-2
