Questions and Answers
  • 1. 

    Mammals are:

    • A.

      Endotherms

    • B.

      Ectoderms

    • C.

      Cells

    • D.

      Fungi

    Correct Answer
    A. Endotherms
    Explanation
    Mammals are endotherms because they have the ability to regulate their body temperature internally. Unlike ectotherms, which rely on external sources of heat to maintain their body temperature, mammals can generate heat through metabolic processes to keep their bodies warm. This adaptation allows mammals to thrive in a wide range of environments and maintain a constant body temperature, which is essential for their physiological functions.

    Rate this question:

  • 2. 

    Mammals have a (blank) circulatory system.

    • A.

      Closed

    • B.

      Open

    • C.

      Half open

    • D.

      Half Closed

    Correct Answer
    A. Closed
    Explanation
    Mammals have a closed circulatory system. This means that their blood is contained within a network of blood vessels and does not come into direct contact with their body tissues. The blood is pumped by the heart through arteries, capillaries, and veins, delivering oxygen and nutrients to the cells and removing waste products. This closed system allows for efficient circulation and helps maintain a constant internal environment.

    Rate this question:

  • 3. 

    Mammals obtain oxygen through:

    • A.

      Lungs

    • B.

      Gills

    • C.

      Pancreas

    • D.

      Liver

    Correct Answer
    A. Lungs
    Explanation
    Mammals obtain oxygen through lungs, which are the main respiratory organs in their bodies. Lungs allow mammals to inhale oxygen from the air and exhale carbon dioxide, a waste product of cellular respiration. Gills are the respiratory organs of aquatic animals, not mammals. Pancreas and liver are important organs in the digestive system and have no role in the process of obtaining oxygen.

    Reptiles have

    • A.

      Scales

    • B.

      Fur

    • C.

      Hair

    • D.

      Feathers

    Correct Answer
    A. Scales
    Explanation
    Reptiles have scales as a distinguishing feature. Scales are protective coverings on their skin that help prevent water loss and provide a barrier against predators. Scales also aid in temperature regulation and provide support for their bodies. Unlike mammals that have fur or hair, and birds that have feathers, reptiles have scales that serve various functions for their survival and adaptation to their environment.

    Rate this question:

  • 5. 

    Reptile's egg are

    • A.

      Hard

    • B.

      Soft

    • C.

      Jell like

    • D.

      Leathery

    Correct Answer
    D. Leathery
    Explanation
    Reptile eggs are leathery because they have a flexible and tough outer shell that provides protection to the developing embryo. This leathery texture allows the egg to withstand the pressure and weight of the parent reptile as well as environmental factors. Unlike bird eggs, which have a hard calcium carbonate shell, reptile eggs have a softer and more pliable shell that allows for gas exchange and water absorption. This adaptation is essential for reptiles that lay their eggs on land, as it helps prevent the eggs from drying out and provides a suitable environment for the embryo to develop.

  • 6. 

    Amphibians are:

    • A.

      Ectotherms

    • B.

      Ectoderms

    • C.

      Fish

    • D.

      Plants

    Correct Answer
    A. Ectotherms
    Explanation
    Amphibians are ectotherms because they rely on external sources of heat to regulate their body temperature. Unlike endotherms, such as mammals and birds, which can generate their own body heat, ectotherms like amphibians depend on their environment to warm or cool their bodies. This is why amphibians are often found in moist habitats, as they need water to keep their bodies hydrated and to regulate their temperature.

    Rate this question:

  • 7. 

    Are reptiles kidneys adapted to saving water?

    • A.

      Totaly

    • B.

      Na I don't think so

    Correct Answer
    A. Totaly
    Explanation
    The given answer "Totaly" suggests that reptiles' kidneys are indeed adapted to saving water. This implies that reptiles have efficient mechanisms in their kidneys to conserve water and prevent excessive loss through urine production. These adaptations may include the ability to reabsorb more water from the filtrate, produce concentrated urine, or modify their metabolic processes to reduce water loss.

    Rate this question:

  • 8. 

    How many chambers do reptiles have on their heart:

    • A.

      3

    • B.

      2

    • C.

      1

    • D.

      4

    Correct Answer
    A. 3
    Explanation
    Reptiles have three chambers in their heart. Unlike mammals and birds, reptiles have a partially divided ventricle, which allows for some separation of oxygenated and deoxygenated blood. This adaptation helps reptiles to efficiently supply oxygen to their body tissues. The three-chambered heart consists of two atria and one ventricle, which pumps blood to both the pulmonary and systemic circuits. This unique heart structure is one of the characteristics that distinguish reptiles from other vertebrates.

    Rate this question:

  • 9. 

    Which type of fertilization do mammals do?

    • A.

      Internal

    • B.

      External

    Correct Answer
    A. Internal
    Explanation
    Mammals undergo internal fertilization. This means that the fertilization of the egg by sperm occurs inside the female's body. Mammals have specialized reproductive organs that allow for internal fertilization, such as the penis and vagina. This type of fertilization increases the chances of successful reproduction as it protects the developing embryo and provides a controlled environment for growth. Internal fertilization also allows for parental care and nurturing of the offspring, which is common among mammals.

    Rate this question:

  • 10. 

    How many heart chambers do mammals have?

    • A.

      4

    • B.

      1

    • C.

      3

    • D.

      2

    Correct Answer
    A. 4
    Explanation
    Mammals have four heart chambers. The heart is divided into two sides, each with two chambers. The two upper chambers are called atria, and the two lower chambers are called ventricles. This four-chambered heart allows for efficient separation of oxygenated and deoxygenated blood, ensuring that oxygen-rich blood is pumped to the body while deoxygenated blood is sent to the lungs for oxygenation.

    Rate this question:

  • 11. 

    Where do most of the amphibians lay eggs?

    • A.

      Sand

    • B.

      Water

    • C.

      Mud

    • D.

      Urine

    Correct Answer
    B. Water
    Explanation
    Amphibians are known for their ability to live both on land and in water. They have a moist and permeable skin that requires constant moisture to prevent dehydration. Therefore, most amphibians lay their eggs in water, where the eggs can develop and hatch successfully. Water provides a suitable environment for the eggs, ensuring that they remain hydrated and that the developing embryos have access to oxygen. This allows the amphibian life cycle to continue, as the eggs hatch into aquatic larvae, such as tadpoles, which eventually undergo metamorphosis and become terrestrial adults.

    Rate this question:

  • 12. 

    Do mammals have different shaped teeth?

    • A.

      Yes

    • B.

      No

    Correct Answer
    A. Yes
    Explanation
    Mammals have different shaped teeth because they have different types of teeth that are specialized for specific functions. For example, incisors are used for cutting, canines for tearing, and molars for grinding. This variation in tooth shape allows mammals to efficiently process different types of food and adapt to their specific dietary needs.

  • 13. 

    Amphibians as a juvenile have a ________ loop circulatory system. 

    • A.

      Single

    • B.

      Double

    • C.

      Triple

    • D.

      3.14159265358979

    Correct Answer
    A. Single
    Explanation
    Amphibians as juveniles have a single-loop circulatory system. This means that their blood flows through the heart and then to the gills or lungs to pick up oxygen, and then it is distributed to the rest of the body. This type of circulatory system is less efficient than a double-loop system found in mammals and birds, but it is sufficient for the needs of amphibians during their early stages of development.

    Rate this question:

  • 14. 

    Amphibians go through:

    • A.

      Metamorphis

    • B.

      Puberty

    • C.

      A toddler phase

    • D.

      Mitosis

    Correct Answer
    A. Metamorphis
    Explanation
    Amphibians go through metamorphosis, which is a process of transformation from an aquatic larval stage to a terrestrial adult stage. During metamorphosis, amphibians undergo significant changes in their body structure and function, such as the development of limbs, lungs, and the ability to live on land. This process allows them to adapt to different environments and is essential for their survival. Puberty is a stage of sexual maturation in mammals, not amphibians. A toddler phase is a term used for human development, and mitosis is a type of cell division, not a stage in amphibian development.

  • 15. 

    A fish breathes through which body organ?

    • A.

      Mouth

    • B.

      Brain

    • C.

      Gills

    • D.

      Fins

    Correct Answer
    C. Gills
    Explanation
    Fish breathe through their gills, which are specialized organs located on either side of their head. Gills are responsible for extracting oxygen from water and removing carbon dioxide. As water passes over the gills, oxygen is absorbed into the fish's bloodstream, allowing it to breathe underwater. The gills are highly efficient in extracting oxygen from water, making them essential for the fish's survival in their aquatic environment.

    Rate this question:

  • 16. 

    Reptiles are _______. 

    • A.

      Ectotherms

    • B.

      Endotherms

    • C.

      Birds

    • D.

      None of the above

    Correct Answer
    A. Ectotherms
    Explanation
    Reptiles are ectotherms because they rely on external sources of heat to regulate their body temperature. Unlike endotherms, such as birds, reptiles do not generate their own body heat through metabolic processes. This means that reptiles are unable to maintain a constant internal body temperature and their body temperature fluctuates with the temperature of their environment.

    Fishes have a ________ circulatory system.

    • A.

      Open

    • B.

      Closed

    • C.

      Half open

    • D.

      Half closed

    Correct Answer
    B. Closed
    Explanation
    Fishes have a closed circulatory system. In a closed circulatory system, blood is contained within a network of blood vessels and does not directly come into contact with the surrounding tissues. This allows for more efficient and controlled circulation of oxygen, nutrients, and waste products throughout the fish's body. Closed circulatory systems are found in more complex organisms, like fishes, as they provide better regulation of blood flow and allow for more specialized functions in different parts of the body.

    • D.

      Tentacles

    Correct Answer
    A. Scales
    Explanation
    Fishes have scales on their skin. Scales are small, hard, and overlapping plates that cover the skin of fishes. These scales provide protection from predators, reduce friction, and help in maintaining buoyancy. They also play a role in thermoregulation and camouflage. The presence of scales is a characteristic feature of most fish species and is essential for their survival in aquatic environments.

    Rate this question:

  • 20. 

    Reptiles have a _______ circulatory

    • A.

      Open

    • B.

      Closed

    Correct Answer
    B. Closed
    Explanation
    Reptiles have a closed circulatory system. This means that their blood flows through a network of vessels and is contained within the vessels at all times. The blood is pumped by the heart and travels through arteries, capillaries, and veins, delivering oxygen and nutrients to the body's tissues and removing waste products. In contrast, an open circulatory system involves the blood being pumped into a body cavity and directly bathing the tissues. Reptiles, like mammals and birds, have a closed circulatory system, which allows for more efficient and controlled circulation of blood throughout the body.

    • A.

      Water; feet

    • B.

      Water; fins

    • C.

      Lava; fins

    • D.

      Lava; feet

    Correct Answer
    B. Water; fins
    Explanation
    Fish live in water because they are aquatic animals that have adapted to survive in this environment. Water provides them with the necessary oxygen for respiration, buoyancy for movement, and a habitat for finding food and shelter. Additionally, fish have fins, which are specialized appendages that help them swim and maneuver through the water. Fins provide stability, balance, and propulsion, allowing fish to navigate their aquatic surroundings efficiently.

    Fishes do _________ fertilization.

    • A.

      Internal

    • B.

      External

    Correct Answer
    B. External
    Explanation
    Fishes do external fertilization because they release their eggs and sperm into the water, where fertilization occurs externally. This method allows for a large number of eggs to be released at once, increasing the chances of successful fertilization. It also allows for genetic diversity as different individuals can contribute to the fertilization process. Additionally, external fertilization is common in aquatic environments where the eggs and sperm can be easily dispersed and where the water provides a suitable medium for fertilization to occur.

      Multipul

    • D.

      Tripple

    Correct Answer
    A. Double
    Explanation
    Reptiles have a double loop circulatory system because they have a heart with two chambers - one atrium and one ventricle. In this system, oxygenated blood is pumped from the heart to the lungs to pick up oxygen, and then it returns to the heart before being pumped to the rest of the body. This double loop allows for efficient oxygenation of the blood and distribution throughout the reptile's body.

    Reptiles obtain oxygen through:

    • A.

      Lungs

    • B.

      Gills

    • C.

      Their feet

    Correct Answer
    A. Lungs
    Explanation
    Reptiles obtain oxygen through their lungs. Unlike amphibians, which can also respire through their skin, reptiles rely primarily on their lungs for oxygen exchange. Lungs are specialized respiratory organs that allow reptiles to take in oxygen from the air and release carbon dioxide. This adaptation enables reptiles to live in a variety of terrestrial habitats and survive in environments with lower oxygen levels than aquatic species.

      5

    • D.

      2

    Correct Answer
    A. 3
    Explanation
    Amphibians have a three-chambered heart. This means that their heart consists of three chambers: two atria and one ventricle. The two atria receive blood from different parts of the body, while the ventricle pumps the oxygenated and deoxygenated blood to different areas. This type of heart allows for some separation of oxygenated and deoxygenated blood, but not as much as in a four-chambered heart, which is found in mammals and birds.

    • C.

      Internal fertilization

    • D.

      Trick question they don't reproduce

    Correct Answer
    C. Internal fertilization
    Explanation
    Reptiles reproduce sexually through internal fertilization, where the male transfers sperm into the female's reproductive tract. This allows for the fertilization of the eggs inside the female's body. Unlike external fertilization, where eggs are fertilized outside the body, internal fertilization provides protection and higher chances of successful reproduction.
