What’s the definition of natural selection

a)

The process of when animals adapt to their environment but become extinct

b)

The processs where they don’t adapt to their environment but reproduce more species

c)

The process which and individual adapt to their environment and produce more of the same species

d)

Evolution

2.

whats the definition of variation

a)

an individual that has a lot of the same characteristics

b)

Any difference between individuals

c)

A group of similar offspring

d)

Natural selection

3.

What’s the definition of evolution

a)

The change in species over time

b)

No change in species over time

c)

Adaptation to their environment

d)

Not adapting to their environment

4.

What’s the definition of homologous structures

a)

Body structures the are different in related species

b)

Body structures that are structurally similar in related species

c)

Body structures that are rare

d)

Body structures that could be endangered

5.

What’s the definition of adaptation

a)

A trait that hurts the organism and fails to reproduce

b)

A trait that helps the organism but fails to reproduce

c)

A trait that hurts the organism Andy reproduces

d)

A trait that helps the organism and to reproduce

6.

Mutations (why helpful)

a)

Change in the chromosomes

b)

Mutations harm the organism

c)

Mutations is the process in which organisms can adapt better

d)

Mutations essential to evolution they cause changes in aspects of life. Without mutations evolution wouldn’t be possible

7.

Species

a)

A group of different organisms that mate with each other’s to produce offspring

b)

A group of the same organisms that don’t mate with each other

c)

A group of organisms that are the same and mate with each other to make fertile offspring

d)

A group of organisms that are the same and mate with each other but don’t make fertile offspring

8.

How are adaptations related to Natural Selection

a)

Because adaptations is how they adapt to they get a trait that helps them survive and Natural selection relates to that because when they reproduce they are better adapted to their environment.

b)

Because adaptations and natural selection are technically the same thing because they both help each other reproduce

c)

They sound a like

d)

Natural selection and adaptations is how the animals and organisms help get better android more comfortable to their environment

9.

Why does a species NEED VARIATIONS in order for natural selection and evolution to occur

a)

More are born then survive (overproduction)

b)

Organisms vary even within their species

c)

Differences between reproduction and survival are due to variation

d)

all of the individuals would have the same chance of surviving and reproducing

10.

How do organisms get adaptations

a)

Natural selection

b)

Variations

c)

Evolution

d)

All of the above

11.

Which organisms are selected during natural selection? WHY??????

a)

The ones that are more likely to survive. Because they produce less of the successful organisms

b)

The ones that are more likely to survive. Because they produce more of the successful organisms

c)

Because of evolution

d)

they are selected because they are more physical.

12.

How could change in the environment lead to evolution.

a)

It would be good because it changes how they survive

b)

It's bad because now they have to spend a lot of time with Natural selection Andy getting used to their new environment while trying to survive

c)

It's good because me they can use two ways of living and surviving

d)

It's bad because now mutations form

13.

How closely related are homologous bones

a)

Similar within different organsism

b)

Similar within related organisms

c)

Different within similar organsims

d)

all of the above
