It might be C but dont quote me on that
Answer:
D. The presence of aquaporins (proteins that form water channels in the membrane) should speed up the process of osmosis.
Explanation:
Water moves in the cells through osmosis which means water moves from its higher concentration to lower concentration. In many animals and plants, water channels are also present which is called aquaporins which allow the water to move through it in and out of cell more quickly.
The rate of diffusion by channel proteins is higher than simple diffusion therefore the aquaporins speed up the process of osmosis. No ATP is required to transport the water through aquaporin channel proteins.
Three lots with parallel side boundaries extend from the avenue to the boulevard as shown in the diagram attached.
Given;
x + y + z = 140 metersAccording to the proportion theorem,
Solving for x, using cross multiplication:
Similarly,
x/40 = z/35
solving for z by cross multiplication,
z = 35x/40
z = 7x/8
Now, the third proportions,
y/30 = z/35
Solving for y,
y = 30z/35
y = 6z/7
x + y + z = 140
4y/3 + 6z/7 + 7x/8 = 140
(224y + 144z + 147x)/168 = 140
224y + 144z + 147x = 23520
Substitutoing z = 7x/8,
224y + (144 × 7x/8) + 147x = 23520
224y + 126x + 147x = 23520
224y + 273x = 23520
Now,
Substitute y = 3x/4
(224×3x/4) + 273x = 23520
168x + 273x = 23520
441x = 23520
x = 53.33
Now,
We know that
y = 3x/4
so,
y = 40
And,
z = 7x/8
Z = 46.66
