Question 1

Both flies and moths will give birth to larvae that must undergo metamorphism in order to transition to its adult form. Which of the following does this suggest?

Accepted Answer

Their embryological development suggests that they are somewhat closely related

Answer

their embryological development suggests that they are not closely related

Answer

their embryological development suggests that they are better adapted from survival

Question 2

Fossil records can be used to support evolution by giving what type of information about various organisms?

Accepted Answer

fossils give some information about the relative age of organisms as well as appearances

Answer

fossils can be used to test relatedness through comparisons of fossilized genomes (DNA)

Answer

fossils show how organisms developed as embryos and can be used to make comparisons with modern day organisms

Question 3

Which of the following best represents homology?

Accepted Answer

both humans and dogs possess a humerus bone, but they look different based on function

Answer

humans and bananas share about 50-60% of their DNA with one another

Answer

bacteria can exchange DNA between individual cells through the use of a pilus

Question 4

Which of the following terms best refers to the comparison of structures believed to have originated from the same common ancestor?

Accepted Answer

homology

Answer

embryology

Answer

biology

Question 5

Which of the following best represents natural selection?

Accepted Answer

a giraffe with a longer neck will have a higher chance of surviving and mating than one with a shorter neck

Answer

both dinosaurs and birds contain a furculum (wishbone) suggesting that they are related

Answer

a cat is spayed to prevent it from having kittens

Question 6

Which of the following best describes an adaptation?

Accepted Answer

the muscles in the hind legs of goats strengthens over generations to better help them climb up steep cliffs

Answer

lionesses hunt by separating slower, weaker prey animals from their herds

Answer

monarch butterfly caterpillars will typically only eat from one food source: the milkweed plant

Question 7

Dodo birds are an extinct species of bird that are related to pigeons and doves. They lived on the Mauritius island near Madagascar, but they were hunted to extinction because they did not express a fear of humans. Pigeons and doves, on the other hand, will quickly fly away if a human gets too close. The reason  pigeons and doves survived whereas the dodo bird did not is an example of which of the following?

Accepted Answer

natural selection

Answer

phylogony

Answer

homology

Question 8

For something to be considered an adaptation, which of the following must be true?

Accepted Answer

there must be a change that better helps it to survive

Answer

there must be a change in color based on the organisms' habitat

Answer

there must be a predator/prey relationship amongst the organisms involved
