Akshara Das answered
Camels have many adaptations that allow them to live successfully in desert conditions. Deserts are hot and dry. Winds blow sand all around, so a camel has long eyelashes. It has nostrils that can open and close.

1. A camel can go a week or more without water, and they can last for several months without food. They can drink up to 32 gallons (46 litres) of water at one drinking session! 
2. Camels store fat in the hump, not water. The fat can be metabolised for energy.
3. Unlike most mammals, a healthy camel's body temperature fluctuates (changes) throughout the day from 34degC to 41.7degC (93degF-107degF.) This allows the camel to conserve water by not sweating as the environmental temperature rises.
4. Camels feet are wide so they can walk on sand more easily. Their huge feet help them to walk on sand without sinking into it.
5. Camels have thick lips so they can eat the prickly desert plants with out feeling pain.
6. The colour of their bodies helps them to blend into their environment.
7. Camel's ears are covered with hair, even on the inside. The hair helps keep out sand or dust that might blow into the animal's ears.

If there is a heavy rainfall on most of the days at a place, the climate of that place will be
  • a)
    Hot and wet
  • b)
    Cold and wet
  • c)
    Hot and humid
  • d)
    Cold and humid
Correct answer is option 'A'. Can you explain this answer?

Prisha Mehta answered
Meteorologists record the weather every day. The records of the weather have been preserved for the past several decades. These help us to determine the weather pattern at a place. The average weather pattern taken over a long time, say 25 years, is called the climate of the place. If we find that the temperature at a place is high most

of the time, then we say that the climate of that place is hot. If there is also heavy rainfall on most of the days in the same place, then we can say that the climate of that place is hot and wet.

Cold blooded animals
  • a)
    Body temperature keeps always high
  • b)
    Keep their body temperature uniform
  • c)
    Change their body temperature with environment
  • d)
    Body temperature always remains less
Correct answer is option 'C'. Can you explain this answer?

Pooja Banerjee answered
Cold-blooded animals do not maintain a constant body temperature. They get their heat from the outside environment, so their body temperature fluctuates, based on external temperatures. If it is 50 degreeF outside, their body temperature will eventually drop to 50 degreeF, as well.

A long winter sleep of animals is called
  • a)
    Cold sleep
  • b)
    Aestivation
  • c)
    Hibernation
  • d)
    Deep sleep
Correct answer is option 'C'. Can you explain this answer?

Mainak Basu answered
Some animals undergo long winter sleep to avoid cold condition, called as hibernation. Organism survive without taking food and water.

Hump of a camel is used to-
  • a)
    tread on the desert land
  • b)
    store fat
  • c)
    store water
  • d)
    both b and c
Correct answer is option 'B'. Can you explain this answer?

Geetika Shah answered
The correct option is B.
A camel's hump does not hold water at all – it actually stores fat. The camel uses it as nourishment when food is scarce. If a camel uses the fat inside the hump, the hump will become limp and droop down. With proper food and rest the hump will return to normal.

Explanation:

Climate is the long-term average of weather patterns that have been observed in a particular place. It is the atmospheric condition that prevails over a long period of time, typically at least 30 years. Climate is different from weather, which refers to short-term atmospheric conditions in a specific location.

Factors affecting climate:
- Latitude: The earth's climate varies with the distance from the equator.
- Altitude: The temperature decreases with the increase in altitude.
- Ocean currents: The ocean currents can affect the temperature and humidity of the air above it.
- Wind: The wind is responsible for moving the air masses, which can affect the climate.

Classification of climate:
- Tropical climate: These regions have high temperature and high humidity throughout the year.
- Temperate climate: These regions have moderate temperature and humidity throughout the year.
- Polar climate: These regions have low temperature and low humidity throughout the year.

Climate change:
Climate change refers to the long-term changes in the earth's climate, including changes in temperature, precipitation, and sea level. Climate change can be caused by natural factors like volcanic eruptions and changes in solar radiation, and human activities like deforestation and burning of fossil fuels.

Conclusion:
In conclusion, climate is the long-term average of weather patterns that have been observed in a particular place. It is different from weather, which refers to short-term atmospheric conditions in a specific location. Climate is affected by various factors like latitude, altitude, ocean currents, and wind. Climate change refers to the long-term changes in the earth's climate, which can be caused by natural factors and human activities.

Which of the following animals have ability to camouflage?
  • a)
    Lion
  • b)
    Grasshopper
  • c)
    Chemolean
  • d)
    Butterfly
Correct answer is option 'C'. Can you explain this answer?

Esha gupta answered
Camouflage is the ability of an animal to blend in with its surroundings, making it difficult for predators or prey to spot them. It is a common defense mechanism used by many animals to increase their chances of survival. Among the given options, the animal that has the ability to camouflage is the Chemolea.

Chemolea:
Chemolea is a type of lizard, also known as a chameleon. Chameleons are famous for their remarkable ability to change the color of their skin to match their environment. They have specialized cells called chromatophores that contain pigments and can expand or contract to modify the coloration of the skin. This ability allows the chameleon to blend seamlessly with its surroundings, making it almost invisible to predators or prey. It can change its color to match the color of leaves, bark, or other objects in its environment. This camouflage helps the chameleon to ambush prey or avoid being detected by predators.

Lion:
Lions, on the other hand, do not possess the ability to camouflage. They have a distinctive appearance with their tawny fur, which helps them blend in with the grasslands and savannahs where they typically live. However, their main hunting strategy relies on stealth and teamwork rather than camouflage. Lions typically hunt in groups, using their strength and speed to overpower their prey.

Grasshopper:
Grasshoppers also do not have the ability to camouflage. They are known for their ability to jump long distances and their vibrant coloration, which often includes shades of green, brown, or yellow. These colors may help them blend in with their natural habitat, such as grass or leaves, to some extent. However, their primary defense mechanism is their ability to jump away quickly from potential threats.

Butterfly:
Butterflies, like grasshoppers, do not possess great camouflage abilities. They are known for their brightly colored wings, which often feature intricate patterns and designs. These colors and patterns serve various purposes, such as attracting mates or warning predators of their toxicity. However, butterflies rely more on their agility and speed to evade predators rather than blending in with their surroundings.

In summary, among the given options, only the Chemolea, or chameleon, has the remarkable ability to camouflage by changing its skin color to match its environment. Lions, grasshoppers, and butterflies rely on other mechanisms for survival, such as hunting in groups, jumping away quickly, or using bright colors as warning signals.

Penguins

Introduction:
Penguins are a group of flightless birds that are highly adapted to life in the water. They are found in the Southern Hemisphere, primarily in Antarctica, but also in South America, South Africa, and New Zealand. Penguins have several unique characteristics that make them well-suited for their aquatic lifestyle.

Body Color:
- Penguins have a distinctive black and white coloration.
- The back and head of most penguin species are black, while their belly and chest are white.
- This coloration helps them blend in with their surroundings when swimming and hunting in the water.
- The black color on their back also helps absorb heat from the sun, keeping them warm in cold environments.

Thick Layer of Skin:
- Penguins have a thick layer of blubber beneath their skin, which helps them stay warm in the frigid waters of their habitat.
- This layer of fat acts as insulation, preventing heat loss and providing buoyancy.
- The blubber also serves as an energy reserve, allowing penguins to survive for extended periods without food.

Additional Adaptations:
- Penguins have streamlined bodies and wings modified into flippers, enabling them to swim swiftly and navigate underwater.
- They have webbed feet that aid in propulsion through the water.
- Their feathers are tightly packed and waterproof, providing excellent insulation and reducing drag while swimming.
- Penguins have a specialized gland that secretes oil, which they spread over their feathers to maintain their waterproofing and enhance their buoyancy.

Conclusion:
In summary, penguins have a white body, a thick layer of skin, and a black color on their back. These adaptations help them survive in their aquatic environment, providing insulation, buoyancy, and camouflage. Penguins are truly remarkable creatures, perfectly suited for life in the Antarctic and other cold regions of the Southern Hemisphere.
