Let's go through each question one by one:

Question 1: You are looking for a model that best displays the information in the incomplete table regarding physical characteristics of several animals. Since I can't view images, I can help you analyze the table:

  • The characteristics of some animals are known, while others are missing (cow and human).
  • For example:
    • Cow: 2 digits on foot (?); hair (?); grasping hands (?); tail (?)
    • Deer: 2 digits on foot (yes); hair (yes); grasping hands (no); tail (yes)
    • Human: 2 digits on foot (?); hair (?); grasping hands (?); tail (?)

You would need to choose the model that best fits these characteristics and also integrates the known data for deer, gorilla, raccoon, and lizard. Without seeing the models, I cannot specify which one would be the best answer.

Question 2: According to the diagram, the two species of the Hominidae that are most closely related are likely: d) Chimpanzees and Bonobos. Chimpanzees and Bonobos are known to share a more recent common ancestor compared to humans or gorillas.

Question 3: According to the cladogram, the trait that only humans have is: b) opposable thumbs. While many mammals have mammary glands and hair, and jaws are present in numerous animals, opposable thumbs are particularly associated with humans and some other primates.

Question 4: Using the cladogram, the two organisms that have the most recent common ancestor are most likely: b) birds and primates. Without the image, I'm making a generalization that birds and primates (being part of the deeper lineage of reptiles and mammals) are closely related compared to the other pairs.

Question 5: According to the phylogenetic tree, the most recent common ancestor of animals and fungi belonged to which kingdom? c) Protista. Animals and fungi are both part of the Eukaryota domain, and they are believed to have a common ancestor within the Protista kingdom.

Please verify the answers with the images you have on hand, as some responses depend on the specifics presented in those diagrams.
