Polar Bears live near the North Pole. What is their home like?
Correct Answer
B. Very cold
Explanation
Polar Bears live near the North Pole, which is known for its extremely cold temperatures. Their home is characterized by icy landscapes, freezing waters, and frigid weather conditions. These bears have adapted to survive in this harsh environment, with thick fur and a layer of blubber to keep them warm. The cold climate is essential for their survival, as it provides them with a habitat rich in seals, their primary food source.
2.
Why do fish like to live in the sea?
Correct Answer
A. They can swim
Explanation
Fish like to live in the sea because they can swim. Swimming is a natural ability for fish, and the sea provides them with the perfect environment to move freely and navigate through the water. Unlike other animals, fish have adapted to live in water and have specialized body structures, such as fins and gills, which allow them to swim efficiently. Therefore, the ability to swim is a primary reason why fish prefer to live in the sea.
3.
Where does the camel like to live?
Correct Answer
C. In the desert
Explanation
Camels are well-adapted to living in the desert. They have specialized features that allow them to survive in extreme heat and arid conditions. Their humps store fat, which can be used as a source of energy and water when food and water are scarce. They also have long legs that help them walk on sand without sinking, and their wide, padded feet help distribute their weight and prevent them from sinking into the sand. Additionally, camels have a unique ability to conserve water by producing concentrated urine and reducing water loss through sweating. All of these adaptations make the desert the ideal habitat for camels.
4.
A tree can be a shelter for a _____________________.
Correct Answer
C. Bird
Explanation
A tree can be a shelter for a bird because birds often build nests in trees to protect themselves from predators and harsh weather conditions. The branches and leaves of a tree provide a safe and secure environment for birds to rest, lay eggs, and raise their young. Additionally, the height of a tree gives birds a vantage point to spot potential threats or food sources. Overall, trees serve as natural habitats and shelters for various bird species.
5.
State whether the following statement is true or false.
Animals that migrate or travel to another area usually do not return.
Correct Answer
B. False
Explanation
False. Animals that migrate or travel to another area often return to their original location. Migration is a seasonal movement of animals from one place to another in search of food, breeding grounds, or better climate conditions. Many species, such as birds, fish, and mammals, have well-established migration patterns and return to their original habitats after completing their journey.
6.
Which of the following is the definition of hibernation?
Correct Answer
A. Option 1
Explanation
Hibernation is a state of dormancy and reduced metabolic activity that certain animals enter during the winter months. It is a survival strategy to conserve energy and withstand harsh environmental conditions. Animals in hibernation experience a decrease in body temperature, heart rate, and breathing rate. They may also go without food or water for extended periods. This allows them to conserve energy and survive when food is scarce. Therefore, Option 1 is the correct answer as it accurately defines hibernation.
7.
Why do animals hibernate or migrate during the winter?
Correct Answer
B. They can no longer find enough food to survive
Explanation
During the winter, animals hibernate or migrate because they can no longer find enough food to survive. The cold weather affects the availability of food sources, such as plants or smaller animals, making it difficult for them to sustain themselves. Hibernation or migration allows them to conserve energy and find more favorable environments with abundant food resources. This behavior ensures their survival during the harsh winter months when food is scarce.
8.
Many bears _______ in the winter, finding a place to sleep lightly during the winter months.
Correct Answer
B. Hibernate
Explanation
Bears hibernate in the winter, which means they find a place to sleep lightly during the winter months. This is a common behavior among bears and many other animals, as they enter a state of reduced activity to conserve energy and survive the harsh winter conditions. During hibernation, bears lower their body temperature, heart rate, and metabolism, and rely on stored fat reserves for sustenance.
9.
What do each of the following animals have in common?
Correct Answer
B. Each of the animals hibernate during the winter.
10.
Is [All animals that hibernate sleep deeply throughout the winter.] true or false?
Correct Answer
A. True
Explanation
The statement "All animals that hibernate sleep deeply throughout the winter" is true. Hibernation is a state of inactivity and metabolic depression that allows animals to conserve energy during the winter months. During hibernation, animals experience a significant decrease in their metabolic rate, body temperature, and heart rate, leading to a deep sleep-like state. This enables them to survive the cold temperatures and scarcity of food during the winter season.
11.
An endangered species is one that is ________
Correct Answer
C. In danger of extinction
Explanation
An endangered species is one that is in danger of extinction. This means that the population of the species is declining at a rapid rate, and if necessary conservation measures are not taken, the species may become extinct in the near future. The term "endangered" is used to classify species that are at a high risk of disappearing from the wild. It is important to protect and preserve these species to maintain biodiversity and ecological balance.
12.
How can we help reduce the amount of rubbish that goes to landfill?
Correct Answer
D. Recycle
Explanation
Recycling is an effective way to reduce the amount of rubbish that goes to landfill. By recycling materials such as paper, plastic, glass, and metal, we can divert them from being disposed of in landfills. Recycling helps conserve natural resources, reduces the need for raw materials and energy, and minimizes pollution and greenhouse gas emissions associated with waste disposal. It is an important step towards sustainable waste management and can significantly contribute to the reduction of landfill waste.
13.
Is [Trash, oil spills, and waste from factories are forms of pollution] true or false?
Correct Answer
A. True
Explanation
Trash, oil spills, and waste from factories are indeed forms of pollution. Trash, such as plastic and other non-biodegradable materials, can pollute the environment and harm wildlife. Oil spills, especially in bodies of water, can have devastating effects on marine life and ecosystems. Waste from factories often contains harmful chemicals and pollutants that can contaminate air, water, and soil, leading to pollution. Therefore, the statement "Trash, oil spills, and waste from factories are forms of pollution" is true.
14.
Why is it a good idea to recycle and reuse things?
Correct Answer
B. To take care of the Earth and living things
Explanation
Recycling and reusing things is a good idea to take care of the Earth and living things. By recycling, we can reduce the amount of waste that goes to landfills and minimize the extraction of raw materials from the Earth. This helps in conserving natural resources and reducing pollution. Reusing items also reduces the need for producing new items, which saves energy and reduces greenhouse gas emissions. By taking care of the Earth and living things through recycling and reusing, we contribute to a healthier and more sustainable environment for future generations.
15.
________means to use less of something.
Correct Answer
Reduce
Explanation
The word "reduce" means to use less of something. When we reduce something, we decrease the quantity, size, or intensity of it. This can be applied to various aspects such as reducing waste, reducing energy consumption, or reducing the amount of a particular substance used. By using less of something, we aim to minimize waste, conserve resources, and promote sustainability.
16.
Camellia sells her doll at a yard sale. Her doll will be ________ by someone else.
Correct Answer
Reused
Explanation
Camellia sells her doll at a yard sale, indicating that she is giving up ownership of the doll. The word "reused" suggests that someone else will now use or play with the doll after Camellia. This implies that the doll will have a new owner who will continue to utilize it, rather than it being discarded or unused.
