21. Which of the following statements regarding Barchan is/are correct?

1. It is a crescent shaped mound of sand, which is deposited by the wind blowing constantly from one DIRECTIONS in a desert.

2. The windward side has a convex steep slope with maximum height at the centre.

3. Two ends of Barchan are called horns and point opposite to the DIRECTIONS the wind blows.

Select the answer using the code given below:

Correct Answer: (d) 1, 2 and 3
Solution:(d)

22. Which of the following statements regarding Regur soil is/are correct?

1. It is a light coloured, clayey and fertile soil.

2. It is developed on Deccan basaltic lava under hot and humid conditions.

3. Cotton is extensively cultivated in this soil.

Select the answer using the code given below:

Correct Answer: (b) 2 and 3
Solution:The Black soil is also known as regur soil and is formed by the weathering of Igneous rocks that form the Deccan plateau. Black soil is developed over Deccan lava granite rocks under semi-arid conditions.

23. Which of the following statements regarding clouds is/are correct?

1. Clouds are classified on the basis of altitude and their form.

2. According to altitude they are classified as High, Middle and Low clouds.

3. Stratus, Nimbostratus and Stratocumulus are high clouds.

Select the answer using the code given below:

Correct Answer: (b) 1 and 2 only
Solution:
  • Clouds are indeed classified based on their altitude (height above the Earth's surface) and their form (shape and appearance).
  • Clouds are commonly classified into three altitude categories: high clouds (cirrus, cirrostratus, cirrocumulus), middle clouds (altostratus, altocumulus), and low clouds (stratus, stratocumulus, nimbostratus).

24. Consider the following statements regarding 'fronts':

1. The movement of a front causes a slow change in weather in the area over which it moves.

2. Cold fronts are associated with thunderstorms.

3. Warm front is the boundary between an advancing mass of warm air where it is overriding and rising above a mass of colder air.

Which of the statements given above is/are correct?

Correct Answer: (d) 1, 2 and 3
Solution:(d)

25. Consider the following statements regarding soils:

1. Soils Laving a very high content of sodium and calcium and pH of more than 7-0 are alkaline soils.

2. Black cotton soil had developed on the Deccan basaltic lava under hot and humid conditions.

3. Laterite soils are characterised by a deep weathered layer from which silica has been leached.

Which of the statements given above is/are correct?

Correct Answer: (c) 2 and 3 only
Solution:
  • Alkali soil have high in pH (above 8.5), making it basic. These clay-rich soils often contain sodium carbonate/bicarbonate, leading to poor drainage and limited nutrient availability for plants.
  • Black soil thrives on basalt plateaus. Weathering of this volcanic rock, rich in iron and minerals, creates fertile soil with dark color from iron oxides and decomposed organic matter. The Deccan Plateau in India is a famous example of black soil formed from basaltic lava.
  • Laterite soils are formed in tropical regions with heavy rainfall. The intense weathering and leaching process removes silica and leaves behind oxides of iron and aluminum, resulting in a soil rich in iron and aluminum compounds. These soils are often red or yellow in color due to the presence of iron oxides.

26. Consider the following characteristics of a grassland:

1. An extensive area of mid latitude grasslands are devoid of trees and shrubs.

2. The climate is characterised by hot summers, cold winters and relatively low rainfall occurring mainly in spring and summer.

3. In humid parts, grasses grow to a meter or more in height.

On the basis of the above characteristics, select the correct grassland from the options given below:

Correct Answer: (b) Prairies
Solution:(b)

27. Which of the following statements regarding animal cell membrane is correct?

Correct Answer: (c) They are composed of phospholipids and proteins only.
Solution:The animal cell membrane consists of phospholipids and proteins only.

28. Which of the following is not a part of compound microscope?

Correct Answer: (d) Retina
Solution:Retina is a part of human eye. Mirror, stage an clip are the parts of a compound microscope.

29. Which one of the following is the correct sequence in increasing complexity?

Correct Answer: (d) Protein - Tissue - Organ - Organism
Solution:As the complexity increases from molecular level to organismic level, so the correct sequence is Protein, Tissue, Organ, Organism

30. Consider the following cell types:

1. Monocyte
2. Chondrocyte
3. Basophil
4. Lymphocyte
How many of the above belong to animal cell types?

Correct Answer: (d) 4
Solution:All the given cell types are animal cell types as monocyte, basophil and lymphocyte are types of white blood cells and chondrocytes are bone cells.
