Answer 4

(05.03 MC) A scientist uses radioactive dating to determine the age of a fossil and discovers that a hominid species may have existed much earlier in history than he thought. Which of the following would most likely increase the reliability of this finding? (1 point)
Select one:
a. Using radioactive dating to determine the age of similarly shaped fossils
b. Repeated analyses of the fossil finding it to be the same age each time
c. Using radioactive dating to find the age of fossils found in the same geographic location
d. Publication of his findings in different paleontology magazines

Answer 5

A.

Answer 6

(05.03 MC) Humans, monkeys, and other primates have more physical characteristics in common than they do with other mammals, like horses, dogs, or mice. These similarities are evidence for a more recent common ancestor among primates than between primates and other mammals. Think about the face, teeth, hands or feet, and offspring of primates, like humans, and of other mammals you may have encountered. Which of the following best describes contrasting physical characteristics between primates and other mammals? (1 point)
Select one:
a. Female primates can give birth to a larger number of offspring at once than most other mammals.
b. Other mammals have greater grasping ability than primates, since primates lack opposable thumbs.
c. The teeth of most primates are much larger in size than in other mammals.
d. Primates have larger, forward-facing eyes and smaller noses than most other mammals.

Answer 7

D.

Answer 8

(05.01 LC) If two different animal species are found to go through equivalent stages of embryonic development until the very last stage, which conclusion would this phenomenon support? (1 point)
Select one:
a. The two animal species are very closely related.
b. The two animal species are both mammals.
c. The two animal species have identical DNA.
d. The two animal species do not share a common ancestor.
