Answer:
The correct statements are: 1, 2, and 3.
Cutting stems can stimulate hormones to start lateral leaf growth.
Some tropisms are controlled by hormones.
Cells grow faster in areas where auxin is concentrated.
Explanation:
Plant hormones such as Auxins perform various roles and helps in the growth and development of the plants. Cutting the main stem of the plant stimulates the auxin hormone and which stimulates the lateral elongation growth of the leaf growth.
Some tropisms are controlled by the hormones such as phototropism by auxin as a high concentration area of the auxin causes cell growth in a particular area and the concentration of auxin is stimulated by light.

Answer:
The Bees find the required nectar in the flower by the "sight as well as the odor and also they receive buzz from the floral electric field".
Explanation:
The nectar are agent that are secreted for pollination, specifically cross-pollination. Bees land into or nearer to the flower. Once they landed they use their proboscis for identifying the nectar or to pick it up. Bees also receive a buzz from the flower's electric field. After sensing that electric field, bees can now identify whether the visit to the flower will be worth or not. As we already know, that bee buzz across the flower is the quest for nectar.
