  • 5. 

    The neurotoxins contained in sea snake venom can cause what kind of symptoms?

    Correct Answer
    blurred vision, drowsiness, respiratory paralysis
    Explanation
    The neurotoxins present in sea snake venom can lead to various symptoms such as blurred vision, drowsiness, and respiratory paralysis. These toxins affect the nervous system, specifically targeting the nerves responsible for vision and respiratory function. Blurred vision occurs due to the interference with the normal functioning of the optic nerves. Drowsiness is a common symptom as the toxins can affect the brain and induce a sedative effect. Respiratory paralysis can occur when the toxins block the signals between the nerves and muscles responsible for breathing, leading to a potentially life-threatening situation.

    Sea snakes can breathe under water?

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    Sea snakes cannot breathe underwater. Although they are adapted to life in the ocean, they still need to come to the surface to breathe air. They have specialized lungs that allow them to extract oxygen from the air, and they have a valve in their nostrils that allows them to close off their airway when submerged. This enables them to hold their breath for extended periods of time while hunting or avoiding predators underwater. However, they cannot extract oxygen from the water like fish or other marine animals.

    • E.

      5

    Correct Answer
    D. 4
    Explanation
    Saltwater crocodiles have a 4-chambered heart. This means that their heart is divided into four separate chambers, including two atria and two ventricles. This type of heart structure allows for efficient oxygenation of the blood, as well as the separation of oxygenated and deoxygenated blood. The 4-chambered heart is a characteristic feature of reptiles, birds, and mammals, and it is an adaptation that enables these animals to have a high metabolic rate and sustain their active lifestyles.

    Sea turtles can stay underwater for up to _________ min. on one breath of air.

    Correct Answer
    40
    Explanation
    Sea turtles have the ability to hold their breath for extended periods of time underwater. This is due to their unique respiratory system and adaptations. They can slow down their heart rate and metabolism, allowing them to conserve oxygen. The average time a sea turtle can stay underwater on one breath of air is approximately 40 minutes. This allows them to forage for food, escape predators, and migrate long distances.
