Consider a field where many plants are specifically pollinated by bees. If there was a sudden increase in the population of a bee predator, such as the dragonfly, we might observe a reduction in the bee population, which would lead to reduced pollination. Select the most likely outcome of this change in the ecosystem. Plants that were bee-pollinated will attract new insect pollinators.

Wind will pollinate plants in this area.

Bees will start to avoid this area because of predation.

The plant community will become smaller and less diverse.

bees will start to avoid this area because of predation

Explanation:

the bees have preditors

many other transport proteins, often called pumps, move materials against a concentration gradient. active transport drives molecules across a membrane from a region of lower concentration to a region of higher concentration. this process, shown in figure 5.1, uses transport proteins powered by chemi- cal energy.

b tumor cells have a cell wall instead of a membrane

explanation:

tumor cells different from normal cells because tumor cells have a cell wall instead of a membrane.
