Freshwater protozoans react to a/an __________ environment by removing water through

  1. hypotonic, turgor pressure

  2. isotonic, a contractile vacuole

  3. hypertonic, a contractile vacuole

  4. hypotonic, a contractile vacuole

D Correct answer
Explanation

Freshwater protozoans live in a hypotonic environment relative to their cytoplasm. Water enters by osmosis, and they use a contractile vacuole to expel excess water.

  2. Restoring

  3. Conservation

  4. Distribution
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Watershed management emphasizes scientific soil and water conservation and tends to increase the biomass production.

Watershed: An area or ridge of land that separates water flowing to different rivers, basins or seas is called as watershed.

The aim of the watershed management is to develop primary resources of land and water to produce secondary resources of plants and animals for use in a manner which will not cause ecological imbalance.
The process of creating and implementing plans, programs and projects to sustain and enhance watershed functions that affect the plant, animal and human communities within a watershed boundary.

Identify the correct statements:
A. Water shed management helps in scientific soil and water conservation.
B. Water harvesting techniques are locally specific and locally benefited.
C. Check dams are practised for the conservation pf seasonally flooded gullies.
D. Groundwater storage techniques are more effective than open-air storage of water.

  1. A, B, C and D

  2. A, C and D

  3. B, C and D

  4. A, B and D
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Water-shed management is the system in which soil and water are conserved by scientific means. Water harvesting techniques help people obtain optimum amounts of water. Check Dams help in collecting water at specific regions and prevent floods. Storage of water below the soil level helps in conservation of water in a better manner. 

So, all the given statements are true. The correct option is "A".

It is necessary to conserve wetland because

  1. It purify surface water

  2. It recharge ground water

  3. It holds back water

  4. Both A and B
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The wetlands are responsible for the trapping of the chemicals and harmful wastes. This results in protection of the aquatic systems. This also helps to purify the water since the sediments and the waste is trapped in these regions. This protects the groundwater. The activity of the organisms in these regions allows recharging the surface and groundwater. 

Thus, the correct answer is option D.

Watershed is

  1. An area that contains streams and rivers that drain into the single large water body.

  2. An area that preserves natural water to recharge zones.

  3. An area that catches rain water.

  4. Both A and C
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

An area or ridge of land that separates water flowing to different rivers, basins or seas is called as watershed. Much of the water comes from rainfall and storm water runoff. Watersheds are usually separated from other watersheds by naturally elevated areas.

Thus, the correct answer is option D.
