Questions and Answers
  • 1. 

    Vertebrates are animals that have a ________________

    Explanation
    Vertebrates are animals that have a vertebral column. The vertebral column, also known as the backbone or spine, is a series of bones called vertebrae that run along the back of an animal. This column provides support and protection for the spinal cord, which is a vital part of the nervous system. Vertebrates include animals such as mammals, birds, reptiles, amphibians, and fish, all of which possess a vertebral column.

    Vertebrates are divided into ________ groups.

    Explanation
    Vertebrates are divided into five groups. This means that within the classification system of vertebrates, there are five distinct categories or classifications. These groups are likely based on certain characteristics or traits that vertebrates possess. Without further information, it is not possible to determine the specific criteria for these groups, but it can be inferred that this division helps to categorize and organize the vast diversity of vertebrate species.

    Birds breathe by ________

    Explanation
    Birds breathe by lungs, just like mammals. Lungs are the organs responsible for the exchange of oxygen and carbon dioxide in the respiratory system. Birds have a complex respiratory system that allows for efficient oxygen intake and delivery to their tissues. Air enters their lungs through the trachea and then flows into specialized air sacs, which act as reservoirs for fresh air. From the air sacs, the air passes through the lungs, where oxygen is absorbed into the bloodstream and carbon dioxide is expelled. This process ensures that birds have a constant supply of oxygen to meet their high metabolic demands.

    In water, frog breathe by ________.

    Explanation
    Frogs breathe through their wet skin when they are in water. Their skin is permeable, meaning it allows gases, such as oxygen and carbon dioxide, to pass through. When a frog is submerged in water, oxygen dissolves in the water and can be absorbed through the frog's skin. At the same time, carbon dioxide produced by the frog's metabolism can also be released through the skin into the water. This process of gas exchange through the skin is called cutaneous respiration and is essential for the frog's survival underwater.

  • 5. 

    On land, frog breathe by ________.

    Explanation
    Frogs breathe on land using their lungs. Similar to humans, frogs have a pair of lungs that allow them to take in oxygen from the air and release carbon dioxide. This respiratory system is essential for their survival when they are out of the water. Frogs also have the ability to breathe through their skin, but this is more efficient in water than on land. Therefore, on land, frogs primarily rely on their lungs to breathe.

    Correct Answer(s)
    A. They breathe by lungs.
    C. They feed their babies milk.
    Explanation
    The characteristics of mammals include breathing by lungs and feeding their babies milk. This is because mammals are warm-blooded animals that have lungs to breathe and produce milk to nourish their young. The other options mentioned, such as reproducing by laying eggs and having a body covered with feathers, are not characteristics of mammals but rather of birds or other non-mammalian animals.

    A turtle is a reptile that breathes by the lungs.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    Turtles are indeed reptiles that breathe using lungs. They have a specialized respiratory system that allows them to take in oxygen from the air. Unlike amphibians, which can also breathe through their skin, turtles rely primarily on their lungs for respiration. This enables them to live in various habitats, including both aquatic and terrestrial environments. Therefore, the statement "A turtle is a reptile that breathes by the lungs" is true.

      Amphibians

    • D.

      Fish

    Correct Answer
    B. Mammals
    Explanation
    Mammals reproduce by giving birth. Unlike other vertebrates such as birds, amphibians, and fish, mammals have developed specialized reproductive systems that allow them to carry their young inside their bodies until they are fully developed. This process is known as viviparity. Mammals have evolved various strategies for giving birth, including live birth and laying eggs that hatch internally. This unique reproductive method sets mammals apart from other vertebrates.

    ________ are animals that don't have a vertebral column.

    Correct Answer
    Invertebrates
    Explanation
    Invertebrates are animals that do not have a vertebral column. This means that they lack a backbone or spine, which is a defining characteristic of vertebrates. Invertebrates make up the majority of animal species on Earth and can be found in a wide range of habitats, including oceans, forests, and deserts. Examples of invertebrates include insects, spiders, worms, and jellyfish. They exhibit a diverse array of body forms and adaptations, allowing them to thrive in various environments.
