I was personally thiinking A, but guess i was wrong D:

Answer 4

) Scientists find evidence that the genes involved in tooth development exist in chickens, even though chickens do not normally develop teeth. The formation of teeth in chickens can be controlled by introducing a virus into chicken embryos that "turned on" their tooth-developing gene. They find that the beaks of the virus-modified chicken embryos contain cone-shaped teeth similar to embryonic crocodile teeth. Which of the following best describes the conclusion that can be drawn from this experiment? (1 point)
Choose one answer.
a. As bird evolution continues, birds like chickens will develop teeth like dinosaurs and reptiles.
b. The growth of teeth in chickens supports the hypothesis of a common ancestor between birds and reptiles.
c. The chickens with teeth are more closely related to crocodiles than they are to regular toothless chickens.
d. With enough genetic engineering, chicken embryos can develop into reptiles like crocodiles.

Answer 6

The image below compares the structure of a bat wing to that of a bird. Based on what you know about the classifications of these animals and the difference in the bone structure of their wings, which of the following is the most logical conclusion about their evolution? (1 point)



Choose one answer.
a. They both descended from a recent common ancestor, making bats more closely related to birds than to other mammals.
b. They both inherited their wings from a common ancestor and then diverged in their other body characteristics.
c. They evolved from a wingless common ancestor and developed wings independently of each other.
d. They evolved from entirely different ancestors but both developed wings in response to similar ecological conditions.

Choose one answer.
a. The jaw became less rectangular and more arched. It also grew smaller and projected less.
b. The jaw became generally larger as hominid forms increased in height.
c. With time, the jaw became less oval-shaped and more rectangular.

As hominids evolved, their litter sizes decreased and their gestation period increased. Which of the following inferences can be made based on this observation? (1 point)
Choose one answer.
a. Reproductive success would increase, since mothers had to carry fewer offspring.
b. Hominids would have less difficulty finding mates, since competition is reduced.
c. Maternal care for offspring would increase due to a greater investment to protect.
d. Offspring would likely migrate in order to expand their territory and find mates.

- All fossils found have been radiocarbon dated to be 130,000 to 35,000 years old.
H. sapiens
- Walk upright, have thumbs used for making tools.
- Large brains
- Bury their dead ceremonially.

As scientists have investigated evolution from a variety of fields, they have found that some of Darwin's original ideas were inaccurate or incomplete. The explanation provided by evolution was updated each time to reflect the new information they found. What does this suggest about the theory of evolution? (1 point)
Choose one answer.
a. It has become a stronger and clearer theory as new information is collected.
b. Scientists are getting closer to proving evolution to be true so it could be called a law.
c. The idea of evolution must be false if scientists have had to make changes to Darwin's ideas.
d. It has become less trustworthy theory as changes have been made to it.
