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 6

Fossil

Answer 6

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

Question 7

Adaptation

Answer 7

a trait that helps an organism survive and reproduce

Question 8

Evolution

Answer 8

the gradual change in a species

Question 9

Natural Selection:

Answer 9

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

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

Relative Dating

Answer 12

a technique used to determine which of two fossils is older

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

What is radioactive dating?

Answer 14

Radioactive Dating: allows scientists to determine the actual age of fossils

Question 15

How does it 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

copy of the shape of the organism that made the mold
