Bio Changes Over Time Targets 1-7 Test Review

Front

How are fossils created?

Back

Fossils are created when traces of organisms get turned into stone, dead organisms are quickly buried for millions of years, or animals get trapped.

Front

What can we infer about animals with dull (flat) teeth?

Back

Animals with dull (flat) teeth likely ate only plants.

Front

What do vertebrates possess in the early stages of development (an embryo)?

Back

In the early stages of development, vertebrates possess gill slits and tails.

Front

Which animals have amniotic eggs?

Back

Turtles and leopards have amniotic eggs.

Front

Where can the oldest fossils be found?

Back

The oldest fossils can be found in the lower layers of sediment.

Front

What is the significance of gill slits in vertebrate embryos?

Back

Gill slits indicate a common ancestry among vertebrates and suggest aquatic adaptations.

Front

What is an amniotic egg?

Back

An amniotic egg is a type of egg that has a protective shell and contains amniotic fluid, allowing for development on land.

Front

What does the fossil record tell us about evolution?

Back

The fossil record provides evidence of how species have changed over time and how they are related.

Front

What is the principle of superposition in geology?

Back

The principle of superposition states that in undisturbed layers of rock, the oldest layers are at the bottom and the youngest are at the top.

Front

How do paleontologists determine the age of fossils?

Back

Paleontologists determine the age of fossils using relative dating and radiometric dating techniques.
