1
What is a scientific theory?
All of these answer choices are correct.
It is supported by a large body of evidence.
An explanation based on observations, experimentation, and reasoning.
It has been thoroughly tested and does not conflict with existing results
2
Using fossil evidence, scientists have come to believe that species have changed over time. What is this called?
natural selection
adaptation
variation
evolution
3
The method of getting desired traits by breeding two individuals is an example of which of the following?
Natual Selection
Artificial Selection
Adaptation
Transitional Genetics
4
Why would mouth shape change as a species evolves?
To become a better swimmer
To allow predators to hunt it easier
The climate is different
Its diet gradually changed as the species evolved.
5
A random mutation will become an adaptation if it helps the species survive and reproduce.
False
True
6
A species could go extinct if:
food becomes more plentiful.
the environment changes drastically and the species cannot adapt.
members of the species have adaptations to enhance survival.
there is less competition for resources.
7
During the early stages of their development, pigs and chickens look very similar(embryology) This is evidence of what?
The two animals evolved from different ancestors
The two animals have the exact same DNA.
The two animals evolved from a common ancestor
The two animals are not related
8
Which of the following is an example of an adaptation that would help an organism survive in their ecosystem?
A white rabbit in the Arctic
A plant in the desert that needs a lot of water
A white squirrel that lives in a dense forest of evergreen trees.
A brown lizard in a brightly colored ecosystem.
9
Which of the following conclusions can be fairly drawn based on the fossil record shown?
The horses hair became thinner over time.
The bones did not change, ehich means they looked the same as present day.
The number of digits (toes) decreased.
As they evolved, the horses became smaller.
10
What is the definition of an adaptation?
Blending in
Making waves along their bellies
Anything that improves an organism's chances for survival
A long strawlike mouth
11
Why do species overproduce, or create a lot of offspring?
Most of the offspring will not survive.
Baby animals are cute.
No one knows.
Most species do not overproduce.
12

threatened
endangered
none of the above - they are fine
extinct
13
What is a scientific theory?
An absolute truth.
The same as a hypothesis
A well tested explanation for how something works.
A best guess about something.
14
Fossil Records
All life based on tracked fossils.
Songs that were written by fossils.
A file cabinet filled with fossils.
15
Which of the following is the
main
reason that species go extinct?
Overpopulation
Inability to adapt
Over hunting
Climate Change
16
Some individuals have traits that make them bettersuited for their surroundings. What happens to these traits with time?
The traits become weaker and less dominant.
The trait will become more common among offspring.
These traits begin to disappear.
The number of offspring will remain the same.
17
A population of bears has been declining. Scientists decide to classify them in a category that means the least danger..
He's sooooo cute!!!!
Endangered
Extinct
Threatened
18
To observe natural selection's effects on a population, which of these must be true?
Changes must happen over generations rather than in the lifetime
A researcher must see the change happening over the life of an organism.
Members of the population must increase or decrease the use of their legs
There can be no harmful mutations in the population.
19
Why would a species not change over long periods of time?
Low or long reproductive times
The DNA is too complex to change
Humans don't destroy anything they touch
They may live in a protected environment that has not changed.
20

Higher
No
Lower

22
Which of the following statements describes the process of natural selection?
Species have inherited traits adapted to their environment survive longer
Populations sharing the same gene pool interbreed and create new species
Farmers select animals with desirable variations for breeding
New species are formed via genetic engineering
23
