Vocabulary Review and Lesson Review's

Question 1

Evolution

Answer 1

Refers to the process in which populations gradually change over time.

Question 2

Artificial Selection

Answer 2

The practice by which humans select plants or animals of breeding based on desired traits.

Question 3

Natural selection

Answer 3

Is the process by which organisms that inherit advantageous traits tend to reproduce more successfully than the other organisms do.

Question 4

Variations

Answer 4

Within a species there are natural differences, or variations in traits.

Question 5

Adaption

Answer 5

An inherited trait that helps an organism survive and reproduce in its environment.

Question 6

Extinction

Answer 6

Is when all of the members of a species have died.

Question 7

Fossils

Answer 7

The remains or imprints of once-living organisms.

Question 8

Fossil record

Answer 8

All of the fossils that have been discovered.

Question 9

Describe what Darwin observed during his voyage on the HMS Beagle?

Answer 9

With the observations he made on this almost five-year journey, Darwin formed a theory about how biological evolution happen.

Question 10

How does the environment impact a species’s survival?

Answer 10

The adaptions become more common in the population, and new adaptions may arise. Over time, the population becomes better adapted to the environment.

Question 11

Why are only inherited traits, not acquired ones, necessary for the process of natural selection?

Answer 11

Inherited traits, are ones you got from your parents and ancestors, not acquired ones. They are necessary for the process of natural selection to reproduce successfully.

Question 12

How are fish adapted to their environment?

Answer 12

They have gills, instead of lungs.

Question 13

How is each of these lizards adapted to its environment?

Answer 13

They can camouflage, to its surroundings to adapt to their environment.

Question 14

How is each of these lizards adapted to its environment?

Answer 14

It inherited its traits from its traits from its parents and ancestors and it can, reproduce successfully.

Question 15

What are two types of evidence that suggest that evolution has occurred?

Answer 15

Structural data, DNA, development patterns, and fossils all support the theory that populations change over time.

Question 16

How do fossils provide evidence that evolution has taken place?

Answer 16

Their is a fossil record, and sediment will cover the fossil.

Question 17

What is the significance of the similar number and arrangement of bones in a human arm and a bat wing?

Answer 17

They had a common ancestor, millions of years ago. Now the bones perform different functions in each type of animal.

Question 18

If you were a scientist examining the DNA sequence of two unknown organisms that you hypothesize share a common ancestor, what evidence would you expect to find?

Answer 18

The same traits, in different types of animals.

Question 19

What do the data suggest about how related turtles are to humans compared to tuna and chimpanzees?

Answer 19

Tuna, has a high number and Chimp’s have a low number, compared to humans.

Question 20

If there are no differences between the amino acid sequences in the cytochrome c protein of humans and chimpanzees, why aren’t we the same species?

Answer 20

Chimps might carry out different traits, and tasks, so they might mean were closer to turtles.

Question 21

Explain why the pattern of differences that exist from earlier to later fossils in the fossil record supports the idea that evolution has taken place on Earth?

Answer 21

It shows the stages, in the sediment, it can show scientists how long ago, they lived and some of their traits.
