Ans: True

Q17: What do animals like snakes, rats do to stay away from intense heat in deserts?

Ans: These animals come out only during night when it is cooler.

Many animals, including snakes and rats, adopt nocturnal behavior in deserts to avoid intense heat. They are often more active during the cooler nighttime temperatures, minimizing their exposure to the scorching heat of the desert during the day. This behavioral adaptation helps them conserve energy and cope with the challenging environmental conditions of deserts.

Q18: What types of leaves are there in desert plants?

Ans: In desert plants, leaves are either absent or very small or are spine-shaped to reduce water loss.

Q19: Adaptation to the environment is essential for the survival of an organism.(TRUE/FALSE)

Ans: True

Adaptation to the environment is essential for an organism's survival, involving traits and behaviors that enhance its ability to thrive in specific conditions.

Q20: Give one example of a desert plant.

Ans: Cactus

Q21: Photosynthesis in desert plants is usually carried out by __________.

Ans: Stem

 In some desert-adapted plants, the stems, rather than leaves, may take on the role of photosynthesis to minimize water loss through transpiration. This adaptation helps them conserve water in arid environments.

Q22: What type of roots do desert plants have?

Ans: Desert plants have roots that go very deep into the soil to absorb water.

Q23: Give two examples of animals living in cold regions.

Ans: Yaks and snow leopard.

Q24: Stem of desert plants is covered with ________ which helps to retain water.

Ans: Waxy layer

The stem of desert plants is often covered with a waxy layer or cuticle, which helps to reduce water loss through transpiration and aids in retaining water in arid environments. This adaptation is crucial for the plant's survival in dry and hot conditions.

Q25: Mountain goats have strong hooves for running up the rocky slopes of the mountain.(TRUE/FALSE)

Ans: True

Mountain goats indeed have strong hooves adapted for running up the rocky slopes of mountains.

Q26: The animals eaten by predators are called __________.

Ans: Prey

Prey- Deer & predator-Lion

Q27: Name one characteristic of an aquatic habitat.

Ans: The presence of water is a characteristic of an aquatic habitat. Oceans, rivers, and ponds are examples.

Q28: The speed of deer helps it to run away from predators.(TRUE/FALSE)

Ans: True

The speed of deer is an adaptation that helps them escape from predators. Deer are known for their agility and speed, allowing them to quickly flee from potential threats, such as predators like wolves or big cats. This ability to run swiftly is a crucial survival strategy in the wild.

Q29: A whale can stay in water for a long time without breathing.(TRUE/FALSE)

Ans: True.

Q30: Lion hunts the deer therefore it is known as ___________.

Ans: Predator

Q31: Name two sea animals that do not have gills.

Ans: Dolphin and whale.

 These marine mammals are mammals, not fish, and they breathe air at the surface through blowholes.

Q32: The long ear of deer has no role in adaptation.(TRUE/FALSE)

Ans: False.

The long ears of a deer play a role in adaptation. Deer have keen senses, including excellent hearing, which is crucial for detecting predators and potential threats. The large, mobile ears help them pick up sounds from a distance, enhancing their ability to sense danger and respond appropriately. This adaptation contributes to their survival in the wild.

Q33: ___________allows dolphins and whales to breathe in air when they swim near the surface of water.

Ans: Blowholes

Blowholes are the openings on the tops of the heads of dolphins and whales that allow them to breathe air when they surface. They are a crucial adaptation for these marine mammals, enabling them to quickly inhale and exhale while swimming in and out of the water.

Q34: Do all living things need food?

All living things require some form of sustenance or nourishment to fulfill their nutritional needs and sustain life processes. The specific type of food varies among different organisms, ranging from sunlight and nutrients for plants to organic matter for animals.

Q35: All living things show growth.(TRUE/FALSE)

Ans: True

All living things exhibit some form of growth, whether it's an increase in size, the development of new structures, or an increase in complexity. Growth is one of the characteristics that distinguish living organisms from non-living entities.

Q36: Food gives living organisms ___________ needed for growth.

Ans: Energy

Food provides living organisms with the energy needed for various life processes, including growth, maintenance, and reproduction.

Breathing

Q37: Breathing is a part of __________.

Ans: Respiration

Breathing is a part of the process of respiration. Respiration involves the exchange of gases, typically oxygen and carbon dioxide, and it includes breathing (the mechanical process of inhaling and exhaling) as well as cellular respiration (the metabolic process occurring within cells to produce energy).

Q38: Plants make their own food by the process of ________.

Ans: Photosynthesis

Q39: We breathe in ________of air and breathe out ___________.

Ans: Oxygen and Carbon dioxide

Q40: Earthworms breathe through ___________.

Ans: Skin

Earthworms breathe through their skin in a process called cutaneous respiration. Their skin is thin and moist, allowing for the exchange of gases, primarily oxygen and carbon dioxide, with the surrounding environment.

Q41: Amount of oxygen released in photosynthesis by plants is _______than oxygen they use in respiration.(MORE/LESS)

Ans: More

The amount of oxygen released in photosynthesis by plants is more than the oxygen they use in respiration. During photosynthesis, plants produce oxygen as a byproduct, and this oxygen is often released into the atmosphere. In contrast, during respiration, plants consume oxygen to generate energy, but the net result is a release of oxygen into the environment.
