Explain how temperatures affects which plants grow in an area.
Lower the temperature, fewer plants will go. If it's too cold, no trees will grow.
100
Explain the types of environmental threats that tropical rainforests are experiencing.
-deforestation -habitat loss
100
What is an independent variable in an experiment?
The variable that is changed on purpose.
100
Problem: Does smoking affect your ability to breathe during exercise? Experiment: Measure the number of breaths per minute of smokers and non-smokers of the same age, weight, and activity levels while they climb stairs. What is the IV?
Smokers vs. non-smokers
100
What does the prefix hypo- mean?
below, under, less
200
Explain how precipitation affects which plants grow in an area.
Less precipitation, fewer plants will grow.

Why is agriculture very successful in a grassland biome? Why is this dangerous for this ecosystem?
Because the soil is very fertile and they receive enough rain. This is dangerous because the soil can quickly become depleted of nutrients.
200
What is a dependent variable in an experiment?
It is what gets measured
200
Problem: Does smoking affect your ability to breathe during exercise? Experiment: Measure the number of breaths per minute of smokers and non-smokers of the same age, weight, and activity levels while they climb stairs. What is the DV?
Number of breaths per minute
200
If the prefix macro- means "large," what do you think the prefix micro- means?
Small
300
Define latitude and altitude. How do these factors affect the organisms that live in a biome?
Latitude is how far away you are from the equator. The further you are from the equator, the colder the temperatures will be. Altitude is how far you are from sea level. The higher your elevation, the colder the climate will be.
300
Overfishing affects which aquatic biomes?
All aquatic biomes
300
Why is the control group in an experiment so important?
Without a control group (the normal, unchanged group) you won't know if your experiment worked
300
Problem: Does smoking affect your ability to breathe during exercise? Experiment: Measure the number of breaths per minute of smokers and non-smokers of the same age, weight, and activity levels while they climb stairs. What is the control group?
Non-smokers
300
If hydro- means "water" and the suffix -lysis means "to split," what do you think the word hydrolysis means?
To split with water
400
The equator passes through the country of Ecuador. But the climate in Ecuador can range from hot and humid to cool and dry. What geological land features could create this range of abiotic factors?
Mountain ranges could cause climate to be different on either side of the mountain.
400
What is the #1 source of pollution for ocean biomes?
Human activities on land
400
Why do you need constants in an experiment?
So that only one variable is tested at a time
400
Problem: Does smoking affect your ability to breathe during exercise? Experiment: Measure the number of breaths per minute of smokers and non-smokers of the same age, weight, and activity levels while they climb stairs. What are some constants in this experiment?
Same age, weight, and activity levels
400
Give an example of a word with the prefix kilo- and explain the word's meaning?
kilometers-one thousand meters kilograms- one thousand grams
500
Why is it hard for trees to survive in the tundra?
It's too cold and dry
500
Why have farmers been known to drain wetlands and therefore destroy them?
Once wetlands are drained, the soil is fertile and good for growing crops.
500
What is the proper format for writing a hypothesis?
If .... (IV)...then....(DV)
500
Problem: Does smoking affect your ability to breathe during exercise? Experiment: Measure the number of breaths per minute of smokers and non-smokers of the same age, weight, and activity levels while they climb stairs. What is the hypothesis for this experiment?
If I don't smoke, then I will take fewer breaths per minute when I exercise.
500
What is the meaning of the prefix iso-?
Equal or same
