Why have the sharks got scales?
Correct Answer
C. Because they can breath in the water with the scales.
Explanation
Sharks have scales to help them swim efficiently in water. The scales reduce drag and turbulence, allowing the shark to move through the water with minimal resistance. Additionally, the scales provide protection against abrasions and parasites. They do not help sharks breathe out of the water or see, but they do assist in breathing by allowing water to flow over the gills.

Why have the sharks got fins and a streamlined body?
Correct Answer
C. Because that helps them swim throught water.
Explanation
Sharks have fins and a streamlined body because it helps them swim through water more efficiently. Fins provide stability and maneuverability, allowing sharks to change direction quickly. The streamlined body shape reduces drag, enabling them to swim faster and with less effort. These adaptations are essential for sharks to catch prey, escape predators, and navigate their marine environment effectively.
3.
What do the sharks eat?
Correct Answer
A. The sharks eat fish.
Explanation
The correct answer is "The sharks eat fish." This is because sharks are carnivorous predators and their diet primarily consists of fish. They have sharp teeth and powerful jaws that are adapted for tearing and consuming fish. While sharks may occasionally eat other marine animals, such as seals or sea turtles, fish are their main source of food.

Why do the birds fly?
Correct Answer
C. Because they have wings.
Explanation
Birds fly because they have wings. Wings are specialized appendages that enable birds to generate lift and propel themselves through the air. The shape and structure of bird wings, including the feathers, allow for efficient flight by providing both lift and control. Feathers are lightweight and flexible, allowing birds to adjust their wing shape and angle to achieve different flying maneuvers. The ability to fly gives birds advantages such as accessing food sources, escaping predators, and migrating to different habitats.
5.
Why doesn't the fish have lungs?
Correct Answer
C. Because they live in the water.
Explanation
Fish do not have lungs because they live in the water. Unlike mammals and some other animals, fish have gills that allow them to extract oxygen from the water. These gills are specialized organs that enable fish to breathe underwater by extracting dissolved oxygen from the water and releasing carbon dioxide. This adaptation allows fish to live and survive in their aquatic environment.
6.
Why do the animals eat?
Correct Answer
D. Because it`s a vital function!
Explanation
The correct answer is "Because it's a vital function!" because animals eat to sustain themselves and obtain the necessary nutrients and energy for their survival and growth. Eating is an essential biological process that allows animals to maintain their bodily functions, repair tissues, and carry out metabolic activities. Without eating, animals would not be able to survive for long periods as they would lack the necessary resources to support their bodies and maintain their health.

Why has the poison dark frog a lot of colours?
Correct Answer
A. Because the bright colours are warnings to other animals of their poisonous toxins.
Explanation
The poison dart frog has a lot of colors because the bright colors serve as warnings to other animals about their poisonous toxins. These frogs are highly toxic, and their vibrant colors act as a visual signal to potential predators that they are dangerous to consume. This warning coloration helps to protect the frog from being eaten, as other animals learn to associate the bright colors with toxicity and avoid them.
8.
What adaptations has the spiny turtle got to swim?
Correct Answer
D. A webbed feet and they are fast.
Explanation
The correct answer is "A webbed feet and they are fast." This is because webbed feet help turtles to swim efficiently by providing more surface area to push against the water. The webbing between their toes allows for better propulsion and maneuverability in the water. Additionally, turtles are generally known for their ability to swim quickly, which aids in their survival and hunting capabilities.
9.
Why are the tiger rat snakes difficult to detect in the environment?
Correct Answer
C. Because of their colouring.
Explanation
Tiger rat snakes are difficult to detect in the environment because of their colouring. Their green and black coloration helps them blend in with their surroundings, making it harder for predators or prey to spot them. This natural camouflage allows them to remain hidden and increases their chances of survival in their habitat.

Why do the domestic yak survive at very cold temperatures?
Correct Answer
B. Because they have very lot hair.
Explanation
The domestic yak is able to survive at very cold temperatures because they have a thick coat of hair. This hair acts as insulation, trapping heat close to their bodies and keeping them warm. The dense hair also helps to protect them from harsh winds and extreme cold conditions, allowing them to thrive in cold environments.
