Most insect pollinators are designed to enable plants to carry out...
1. Self Pollination
2. Cross pollination

cross pollination

Explanation:

plants dont want self pollination.  Self pollination is taking pollen from one flower of a plant to another flower of the same plant (plants can have multiple flowers).  Plants don't want this because they want to widen the gene pool meaning they want to reproduce with other plants of the same species.  Cross pollination fits this description.  Cross pollination is taking pollen from one flower to another plant from the same species's flower.  Plants dont want to reproduce with themselves, they want to reproduce with other plants from the same species.  Cross pollination is the best way to do that

plants need sunlight, water, and carbon dioxide to make food. plants use the raw materials of water, nutrients they absorb from soil, and carbon dioxide to make sugars the plant can use. energy from the sun and chlorophyll are also needed.

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.
