Darwin's finches each had a different beak. This shows that

beaks were adapted based on food supply

How are viral and bacterial diseases different?

viral symptoms are treated but bacterial can be cured.

How does biodiversity affect evolution?

more biodiversity means more species arise

Does new evidence support a law or a theory?

a theory because it explains patterns of change

What happens to a species if its habitat was destroyed?

the species would eventually become extinct from not hunting

How is scientific knowledge accepted within the scientific community?

when it is debatable and confirmed by the community

What impact would global warming have on a species of fish that lives along the coast?

fish adapted for warmer water will survive and others won't

occurs as useful traits are passed to offspring

What do the fossil records show

that extinct species share similarities to current ones

How can you tell what a person has eaten?

blood contains nutrients absorbed from food

Questions 21

Answers

1
Which system will make you jerk back if you are poked with something sharp?
circulatory
respiratory
musculoskeletal
immune
2
How does the circulatory system help maintain homeostasis?
by removing oxygen
by removing nutrients
by helping to release heat
by storing urine in the blood
3
Darwin's finches each had a different beak. This shows that
beaks were adapted based on food supply
beaks were adapted based on mating needs
beaks were adapted based on latitude
beaks were adapted based on climate
4
A multi-cellular organism that thrives in warm moist places is a
bacterium
protist
virus
fungus
5
Which of the following help the body maintain homeostasis by removing wastes?
muscular and immune
respiratory and excretory
circulatory and reproductive
digestive and nervous
6
How are viral and bacterial diseases different?
viral symptoms are treated but bacterial can be cured.
viral cause symptoms while bacterial do not
viral can be cured by bacterial cannot
you get viral from the environments but not bacterial
7
How does biodiversity affect evolution?
high biodiversity mean less evolution
more biodiversity means more species arise
less biodiversity creates more time for species to adapt
low biodiversity keeps population size down
8
A single-celled organism that causes strep throat would be a
virus
bacteria
fungi
protist
9
Does new evidence support a law or a theory?
a theory because it explains patterns of change
a theory because the evidence is only analyzed one way
a law because it connects different things
a law because it's how things occur in possible conditions
10
What happens to a species if its habitat was destroyed?
the species would extend the range of their habitat
the species would eventually become extinct from not hunting
the species would quickly change haw they catch their prey
the species would change their diets
11
Why do organisms reproduce?
to absorb nutrients from food
to pass genes to offspring
by removing wastes from the body
to allow the brain to control the body
12
How is scientific knowledge accepted within the scientific community?
when it is accepted by all members of the community
when society approves it
when it is published in journals
when it is debatable and confirmed by the community
13
Which system will provide the oxygen you need for your muscles?
excretory
digestive
immune
circulatory
14
Which systems provide oxygen and remove carbon dioxide?
circulatory and respiratory
respiratory and excretory
respiratory and digestive
circulatory and digestive
15
What impact would global warming have on a species of fish that lives along the coast?
all fish will die and others will move in their place
fish adapted for warmer water will survive and others won't
all fish would survive
the species would change to one that tolerates the heat
16
The organism that causes a cold is a
protist
fungi
bacteria
virus
17
Natural selection
occurs as a completely random process
ensures no chance of extinction
occurs as useful traits are passed to offspring
removes all negative traits in a population
18
What do the fossil records show
that extinct species share similarities to current ones
shows all species that have ever existed
that extinct species are genetically identical to now
that all extinct species became fossilized
19
Which system protects the body from disease?
immune
digestive
excretory
circulatory
20
How can you tell what a person has eaten?
blood contains nutrients absorbed from food
blood contains particles of undigested food
blood contains white blood cells from foods
blood changes color based on food
21
Which system controls the body using the brain?
excretory
immune
nervous
circulatory
