Question 1
1 / -0

Plants in cold regions shed leaves because of

A
Cold weather

B
Water scarcity

C
Longer nights

D
Shorter days

Solution

Plant actually shed their leaves in winter, because they suffer from drought or water scarcity. Deciduous plants lose their leaves to conserve water or to better survive winter weather conditions, they must regrow new foliage during the next suitable growing season.
So, the correct answer is 'Water scarcity'.
Question 2
1 / -0

Which of the following departments prepare weather reports?

A
Pollution department

B
Health department

C
Meteorological department

D
Environment department
Solution
- The Indian Meteorological Department is an agency of the Ministry of Earth Sciences of the Government of India. It is the principal agency responsible for meteorological observations, weather forecasting, preparing weather reports and seismology (the study of earthquakes).
- So, the correct answer is option C.
Question 3
1 / -0

Which of the following instruments is used to measure rainfall?

A
Barometer

B
Thermometer

C
Rain gauge

D
All of the above

Solution

The instrument which is used to measure the rainfall is called rain gauge. Rainfall is generally measured in millimetres.
An instrument that is used to measure atmospheric pressure is known as a barometer.
The instrument used to measure the temperature is known as a thermometer.
Thus, the correct option is C.
Question 4
1 / -0

An animal is taken to polar region. Which of the following adaptive characteristic may help it to survive in the new environment?

A
Growth of thick and less hairy skin

B
Sharp beaks and strong claws

C
Growth of thick fur on its skin

D
Light weight wings to fly

Solution

The development of characteristics which helps an organism to survive in a particular environment is known as adaptation. Animals possess a wide range of structural and functional adaptive features. Animals taken to polar regions may have the following adaptive features:
1. Low surface area to volume ratio
2. Small extremities to reduce heat loss - shorter ears and limbs
3. Thick layer of body fat/blubber - present in seals to reduce body heat loss
4. Thick camouflaged fur
5. Thick fur on paws
So, the answer is C.
Question 5
1 / -0

Some animals living in water have streamlined body shapes. This helps in:

A
Store food and fats

B
Reduce resistance in water

C
Reduce loss of water

D
Keep the body warm
Solution
- Aquatic organisms have a streamlined body shape. Streamline is defined as a shape that is wider at the centre and narrows down towards the periphery.
- While swimming, it provides the least amount of resistance, facilitating easy movement as well as increasing speed.
Question 6
1 / -0

Pattern of the rainfall depends on the pattern and number of __________ .

A
Water pump

B
Water bodies

C
Human population

D
Noe of the above
Question 7
1 / -0

Underwater divers wear ............ to move easily in water.

A
A head torch

B
Oxygen cylinder

C
Flippers

D
A watch

Solution

Underwater divers wear fin-like flippers, because, the fin-like flippers aid in swimming easily. The shape of the flippers is such that it can easily pass through water. This makes swimming easy and hence reduces the effort of the muscles in swimming. Since fins provide a wider area to push and move against the water, divers need not use their hands anymore to move underwater.
So, the correct answer is 'Flippers'.
Question 8
1 / -0

Plants are killed in winter by frost

A
Because of dessication and mechanical damage to the tissue

B
Because no photosynthesis take place at such a low temperature

C
Because respiration ceases at such low temperature

D
Because there is no transpiration
Question 9
1 / -0

A leaf insect looks like leaves and a polar bear living in snowy regions has white fur on its skin. Although these animals are very different from each other, what is the one way in which they are similar?

A
They use their bodies to attack enemies.

B
They use their bodies to confuse enemies.

C
They use their bodies to prepare food.

D
They migrate to long distances to protect themselves from enemies.
Solution
- Polar bears have white fur so that they can camouflage (a phenomenon to confuse predators) into their environment. Their coat is so well camouflaged in Arctic environments that it can sometimes pass as a snowdrift.
- The leaf insect exhibits mimicry where it resembles an unrelated species of organism (plant leaf) to save itself from predation.
So, the correct answer is option B.
Question 10
1 / -0

Water scarcity is usually found in

A
Desert conditions

B
Polar regions in winter

C
Only A

D
Both A and B
Solution
- Water scarcity is the lack of fresh water resources to meet water demand. Water scarcity is seen in desert regions because the precipitation is very less and rainfall is also minimum.
- During winter in polar regions, water is converted into ice due to very cold temperatures. This, in turn, leads to water scarcity in polar regions.
- So, the correct answer is 'Both A and B'.
