Question
d. increase the pH of the cell wall, thus decreasing the solute potential outside the cell. 35. Gibberellic acid plays a role in seed germination by: a. breaking down starches to smaller sugar molecules. b. stimulating release of the enzyme amylase. c. producing aleurone which the embryo uses to start growing d. causing water to dissolve the aleurone layer so that sugars are produced. 36. Normal functioning of the glomerulus in the mammalian kidney is a manifestation of a. pressure potential. b. counter-current exchange c. solute potential. d. a huge number of sodium-potassium pumps. 37. As the fluid inside the descending limb of a nephron moves toward the ascending limb, a. the solute concentration in the fluid continually decreases. b. the pressure potential of the fluid continually decreases. c. the solute potential of the fluid continually increases. d. the solute potential of the fluid continually decreases.Explanation / Answer
answer to question 35. option b is correct - stimulating release of the enzyme amylase.
Because gibberline acid has positive seed dormancy effect .
means this plant hormone enhances the production of alpha amylase , which ultimately increases the time exposure to the hormone(gibberlline acid ), and this show a detectable stimulation in the aleurone layer and thus helps in seed germination.
Answer to question 36. OPTION A- pressure potential
it is beacause a variety of partial pressure are acting in the glomeruli which are resulting in net filteration of blood ,
like glomerular hydrostatic pressure and osmotic pressure and the force of the difference in these potentials cause filteration.
Answer to question 37. option -a -the solute concenteration in the fluid , continously decreases .
because ,the solute in the fluid or urine , are maximally absorbed , in the ascending limb , which causes more and more Nacl resorption , so solute concenteration in the fluid continously decreases.
