Answer:

Option D, Five radish plants are grown in sunlight, while another five radish plants are kept in the dark.

Explanation:

In a controlled experiment, impact of one independent variable is studied on the dependent variable.  

Here in this study sunlight is the independent variable while the radish plant is dependent variable.  

The researcher wants to study the effect of sunlight on radish plants when they are exposed to it   and compare it to the effect created on radish plants  that are kept in dark.  

Hence option D is correct.

Which of the following statements about osmosis is correct?
Pavlova-9 [17]

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.
