Changes Over Time Test

Question 1

Can you give an example of the diversity of living things?

Answer 1

A fish can breathe underwater and a lion can breathe on land.

Question 2

Can you give an example of the fossils that Darwin observed?

Answer 2

Darwin found that fossil bones back then were much larger than those of the sloths that were alive in his time

Question 3

What did Darwin hypothesize about the Galapagos Islands?

Answer 3

Darwin hypothesized, the species gradually changed over many generations and became better adapted to new conditions

Question 4

How does the “Battle of the Beaks” lab relate to the idea of natural selection?

Answer 4

Based on how effective your beak was then you would either survive or die. Exactly like natural selection

Question 5

a group of similar organisms that can mate with each other and produce fertile offspring

Answer 5

Species

Question 6

the preserved remains or traces of an organism that has lived in the past

Answer 6

Fossil

Question 7

a trait that helps an organism survive and reproduce

Answer 7

Adaptation

Question 8

the gradual change in a species

Answer 8

Evolution

Question 9

the process in which individuals that are better adapted to the environment are more likely to survive and reproduce than other

Answer 9

Natural Selection:

Question 10

What parts of an organism usually form fossils?

Answer 10

The bones

Question 11

What, other than sediment, can fossils be preserved in?

Answer 11

Ice

Question 12

a technique used to determine which of two fossils is older

Answer 12

Relative Dating

Question 13

If you were given data about the location of a preserved fossil in relationship to the top of the soil, how do you tell which fossil is older?

Answer 13

You can tell which fossil is older by how deep it is in the sedimentary rock

Question 14

allows scientists to determine the actual age of fossils

Answer 14

Radioactive Dating:

Question 15

How does radioactive dating determine the age of a fossil?

Answer 15

It determines the age of a fossil because it allows you to measure the difference/quantity of parent isotopes and daughter isotopes to see which one is older

Question 16

a fossil formed when minerals replaces all or part of the organism

Answer 16

Petrified Fossil

Question 17

hollow space in a sediment in the shape of an organism

Answer 17

Mold

Question 18

copy of the shape of the organism that made the mold

Answer 18

Cast

Question 19

What are some similarities that existed among the organisms on the mainland and island?

Answer 19

There both lizards

Question 20

What are some differences that existed among the organisms on the mainland and island?

Answer 20

Long claws for Galapogas islands and short claws for Galapogas islands
The same species of bird looked different at every island

Question 21

What’s an example of a difference

Answer 21

if two lizards lived on two separate island. One with rocks and one with grass. The lizard that lives by the rocks would have grippy feet and the one with grass would ahve soft feet.

Question 22

Would a rose or snail produce a fossil? Why?

Answer 22

A snail because of its shell

Question 23

How do most fossils form?
What are the steps?

Answer 23

First, the organism dies (skin and meat go away)
Sediment covers the animal or organisms that dies
Pressure and heat are present in the sediment
Minerals dissolve in water
Then it soaks into the remains then enter and preserve the fossil

Question 24

How many billion species have been identified in todays world

Answer 24

1.7 million

Question 25

True or False Darwin found a small diversity of animals in his travels?

Answer 25

False he found a large diversity

Question 26

True or False: Darwin hypothesized that species and organisms die and reproduce once given new conditions?

Answer 26

False he hypothesized species generally change over time and become adapted to new conditions
