A dam is built across a river to generate electricity. What is likely effect of the construction of a dam on the river?

a)increase in the size of fish in the river
b)increase in the water flow in the river
c)decrease in the population of aquatic organisms in the river
d)decrease in the amount of pollutants dumped into the river

Answers

Answer 1

Answer:

c i think

Explanation:

Answer 2

Most likely the effect of the construction of a dam on the river is that it decreases the population of aquatic organisms in the river. Thus, the correct option is C.

What is Population?

A Population may be defined as the group of individuals significantly belonging to the same species living in the same area in a definite time period.

When a dam is built across a river in order to generate electricity, it results in the reduction of the population of aquatic organisms in the river.

This is because the whole construction affects the natural habitat of aquatic organisms as well as their adaptations. So, such populations are frightened due to external construction and do not play their essential roles.

Therefore, most likely the effect of the construction of a dam on the river is that it decreases the population of aquatic organisms in the river. Thus, the correct option is C.

What conditions are necessary for rocks to melt?

Answers

Answer:

In explanation.

Explanation:

The rock is pulled down by movements in the earth's crust and gets hotter and hotter as it goes deeper. It takes temperatures between 600 and 1,300 degrees Celsius (1,100 and 2,400 degrees Fahrenheit) to melt a rock, turning it into a substance called magma (molten rock).

The rock can be melted when high pressure and high temperature are applied to it, and due to the compression relaxation, the rock melts. The different types of rocks need different temperatures.

What is the effect of temperature on different substances?

Temperature plays an important roles in different substances, such as high and low temperatures, each with its own set of tasks. The high temperature can melt the solid substance into a liquid, and further heating converts the liquid into gas. Because of the high pressure and temperature in the earth's core, the rock is in a molten state, but when it comes out of the earth's core, after solidifying, it converts into solid rock. The low temperature converts the liquid into a solid, and food preservation is carried out by this process.  

Hence, the rock can be melted when high pressure and high temperature are applied to it, and due to the compression relaxation, the rock melts.

What percentage of our usable freshwater is already polluted?

Answers

Answer:

3% of the earth's water is fresh. 2.5% of the earth's fresh water is unavailable: locked up in glaciers, polar ice caps, atmosphere, and soil; highly polluted; or lies too far under the earth's surface to be extracted at an affordable cost. 0.5% of the earth's water is available fresh water

Explanation:

please give brainliest

Answer:

Water covers about 71% of the earth's surface.

326 million cubic miles of water on the planet

97% of the earth's water is found in the oceans (too salty for drinking, growing crops, and most industrial uses except cooling).

320 million cubic miles of water in the oceans

3% of the earth's water is fresh.

2.5% of the earth's fresh water is unavailable: locked up in glaciers, polar ice caps, atmosphere, and soil; highly polluted; or lies too far under the earth's surface to be extracted at an affordable cost.

0.5% of the earth's water is available fresh water.

If the world's water supply were only 100 liters (26 gallons), our usable water supply of fresh water would be only about 0.003 liter (one-half teaspoon).

In actuality, that amounts to an average of 8.4 million liters (2.2 million gallons) for each person on earth.

This supply is continually collected, purified, and distributed in the natural hydrologic (water) cycle.

Cactuses can store water nearly four months mainly in the winter and watering is not required for them frequently during that time. The stem acts as a reservoir for the amount of water it holds. The ground tissue of cactus has lots of parenchymal cells that store water.

What is parenchyma?

The ground tissue system comes from a ground meristem which has three tissues, namely parenchyma, collenchyma, and sclerenchyma.

The ground tissue of cactus has many parenchyma cells that store water.

Thus, it can be concluded that the ground tissues helps cactus to store water for a long time.
