Answer:
Option B, Apply auxin directly to the lower part of the stem opposite from the direction you want the stem to bend.
Explanation:
Options for the question are
A) Apply auxin directly to the shoot tip on the side to which you want the tip to bend.
B) Apply auxin directly to the lower part of the stem opposite from the direction you want the stem to bend.
C) Inject compounds that block auxin receptors into the part of the stem opposite from the direction you want the stem to bend.
D) Plant the roots in two different pots, and apply auxin to the root bucket that is on the same side as the direction you want the plant to bend.
Solution
Auxin is responsible for stem elongation by inhibiting growth of lateral buds. The movement of auxin is opposite to the direction of elongation of cells. Generally, Auxin moves to the dark side which is opposite to the direction i.e the lighter side in which cell elongate . Due to this growth pattern, the stem tip gets curved towards the light.
Hence, option B is correct

Answer: A. Increase in temperature
Coastal upwelling is the process in which the deep water rises above the top most water level as the wind pushes water offshore. Nutrients which are present in the bottom layer get available to organisms living in the uppermost layer. The deeper water lacks oxygen because the decomposition of organic matter at the bottom of the water body consumes up available oxygen. Also, because of these water layer turnover will result in thermocline: temperature variation among the layers of water. Bottom layer water because of such decomposition processes will have more temperature when this water rises in the upper layer due to upwelling this will increase the temperature of the upper layer.
