  • 13. 

    __________ locomotion also means "fast running".

    Correct Answer(s)
    cursorial
    Explanation
    Cursorial locomotion refers to the ability of an animal to run quickly. The word "cursorial" is derived from the Latin word "cursor," which means "runner." Therefore, the correct answer is "cursorial" because it directly translates to "fast running."

    Rate this question:

  • 14. 

    Running speed is a function of two basic factors: ______ ___ ___ _____ and speed of limb movement.

    • A.

      Stride of the animal

    • B.

      Length of the stride

    • C.

      Movement of the stride

    • D.

      Quickness of step

    Correct Answer
    B. Length of the stride
    Explanation
    Running speed is determined by two main factors: the length of the stride and the speed of limb movement. A longer stride allows an animal to cover more ground with each step, resulting in a greater distance covered over time. Additionally, the speed at which an animal moves its limbs also contributes to its running speed. By increasing both the length of the stride and the speed of limb movement, an animal can achieve a faster running speed.

    Rate this question:

  • 15. 

    T/F: Length of stride is commonly increased by increasing the length of the legs.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    Increasing the length of the legs can indeed increase the length of the stride. This is because longer legs provide a greater distance between each step, allowing for a longer stride. Additionally, longer legs can also provide more power and leverage, which can further contribute to an increased stride length. Therefore, it is true that lengthening the legs commonly leads to an increase in the length of the stride.

  • 21. 

    Animals that stand primarily on all of their digits is considered a ___________ animal.

    Correct Answer(s)
    digitigrade
    Explanation
    A digitigrade animal is one that primarily stands on its digits, with the rest of its foot elevated off the ground. This type of locomotion is commonly seen in animals such as dogs, cats, and birds. By standing on their digits, these animals have a more efficient and agile way of moving. This adaptation allows them to move quickly and quietly, making them effective hunters or escape artists.

    Rate this question:

  • 22. 

    Animals that stand primarily on all structures of their feet are conisdered _____________ animals.

    Correct Answer(s)
    plantigrade
    Explanation
    Animals that stand primarily on all structures of their feet are considered plantigrade animals. This means that their entire foot, from the heel to the toes, comes into contact with the ground when they walk or run. Examples of plantigrade animals include humans, bears, and raccoons. This is in contrast to digitigrade animals, such as dogs and cats, who walk on their toes, and unguligrade animals, such as horses and deer, who walk on the tips of their toes or hooves.

    Rate this question:

  • 23. 

    Animals that stand primarily on the tips of their toes are considered ____________ animals.

    Correct Answer(s)
    unguligrade
    Explanation
    Unguligrade animals are those that primarily stand on the tips of their toes. This means that their weight is borne by their hooves or claws, rather than the entire foot. This adaptation allows for greater speed and agility, as well as specialized movements such as galloping or climbing. Examples of unguligrade animals include horses, deer, and cats.

      Strong axial support structure

    • B.

      Large attachment surfaces for powerful wing muscles

    • C.

      Light body weight

    • D.

      Light but strong wings

    • E.

      Tail

    Correct Answer(s)
    A. Strong axial support structure
    B. Large attachment surfaces for powerful wing muscles
    C. Light body weight
    D. Light but strong wings
    Explanation
    To be capable of powered flight, an animal needs a strong axial support structure to provide stability and withstand the forces generated during flight. Large attachment surfaces for powerful wing muscles are necessary to generate the necessary lift and propulsion. A light body weight is important to reduce energy expenditure and allow for efficient flight. Additionally, the wings must be light but strong to withstand the stresses of flight. A tail, while beneficial for maneuverability in some flying animals, is not necessarily a requirement for powered flight.
