  • Q12

    Every living organism can be categorized into one of 6 kingdoms (archaea, bacteria, protists, fungi, plants, and animals) based on its cell type, number of cells and mode of nutrition. 

    Which classification has an accurate set of characteristics listed?

    1-Fungi

    4- Protists

    2-Animals

    3-Plants

  • Q13

    The following animals need to be grouped based on common characteristics.

    Parrot - Tree Frog - Striped Bass - Tiger - Tortoise - Praying Mantis - Flowerpot Snake  - Giant Panda - Mexican Burrowing Toad - Nurse shark - Snowy owl  - Golden Silk Spider

    Which approach for grouping all of the animals is the BEST to implement?

    The animals can be grouped based on whether they live in the water or on land. The animals in the two groups will have different methods of breathing.

    The animals can be grouped based on whether or not they have a backbone. All of the organisms will either have a backbone or they will not.

    The animals can be grouped based on whether or not they are insects. Insects will have multiple pairs of legs while non-insects will have one pair of legs.

    The animals can be grouped based on whether or not they have wings. The organisms in the two groups will have different methods of movement.

  • Q14

    Why do the number of organisms in a group change from the first step to the last step of a dichotomous key?

    The number of organisms stays the same because the number of common characteristics of the organisms in a group decreases by half in the last step.

    The number of organisms decreases because the number of common characteristics of the organisms in a group increases.

    The number of organisms is always cut in half because the number of common characteristics of the organisms in a group decreases by half in the last step.

    The number of organisms increases because the number of common characteristics of the organisms in a group increases.

  • Q15

    A student made this model to show the relationships between a shark, a dolphin, a deer, and a lizard based on their characteristics.

    After making the model, the student learned that despite their very different appearances, dolphins and deer are both mammals, and are the most closely related of the animals named in the model.  

    Which revision shows how the student could change the second level of their model to BEST represent the correct scientific relationship between the four animals and allow the deer and dolphin to be grouped together?

    Question Image

    Revise the groups in the second level to "eats meat" and "eats plants."

    Revise the groups in the second level to "breathes with lungs" and "breathes with gills."

    Revise the groups in the second level to "warm blooded" and "cold blooded."

    Revise the groups in the second level to "lives on land" and "lives in water."
