One negative impact of building a dam could be that it affects natural habitats of animals who live in and around the river. When you build a dam, the river's height becomes smaller because a huge amount of water becomes technically removed or blocked. This can affect animals such as fish or beavers or anyone who needs that water.

barxatty [35]

Answer:

a. water into root hair cells

Explanation:

Osmosis can be defined as a process which typically involves the movement of a solvent molecule such as water through a semi-permeable from a region of high concentration to a region of lower concentration.

Hence, the process of osmosis is best illustrated by the movement of water into root hair cells because they are used by the plants to absorb water from the soil.

Orlov [11]

Answer: The appropriate information that will be used to fill the blanks includes the following respectively:

-1.7

- increased

-70%

- 0.5

- decreased

- 50%

Explanation:

The green (topmost) data point at June 2011 shows a proportional change of about 1.7, which means that the native fish population INCREASED by about 70 percent when 95 percent of the lionfish were removed. In contrast, the orange data point at June 2011 shows a proportional change of about 0.5, which means that the native fish population DECREASED by about 50 percent when only a quarter of the lionfish were removed (a result that was almost the same as when none of the lionfish were removed).

The native fishes are being haunted by the lion fish, from the results, removing just few of the invasive lion fish will not make a difference. In other to help the native fish survive, many of the lion fish has to be removed.
