Which of the following plant hormones is responsible for the activation of lateral buds to grow into new branches? which of the following plant hormones is responsible for the activation of lateral buds to grow into new branches?
a. auxin
b. cytokinin
c. ethylene
d. abscisic acid

(a) Auxin

Explanation: The plant hormones responsible for the activation of lateral buds to grow into new branches is the auxins.

The auxins effect the elongation plants stem, stop the growth of lateral buds thereby maintaining apical dominance. They are formed in the

plants stem, buds, and tips of root. An example of Auxin is the Indole Acetic Acid (IA). The Auxin is a plant hormone produced in the stem tip which effects cell elongation.

the best answer is d because the strong cohesion is caused by the ability of water molecules to undergo hydrogen bonding.

a is incorrect because when water solidifies, it becomes   ice, which expands and occupies a bigger volume for the same mass of water in its liquid state.

b is incorrect because water has high surface tension. besides bonding to itself it hydrogen bonds to other molecules at the top decreasing possibility for breaking of attractive forces.

c is incorrect because the water molecule has oxygen which is highly electronegative and so pulls the electron pair towards itself creating a dipole moment, making the molecule polar.

e is incorrect because water has strong adhesion, ability to stick to other molecules such as glass because of this molecules having stronger hydrogen bonding than water.
