5
A new chunk of rock is exposed after a glacier retreats. This is an example of:
Primary Succession
Secondary Succession
6
Prokaryotic cells do NOT have
DNA

Membrane bound organelles
7
Deserts have very little rainfall which leads to a low amount of biodiversity. Why?
More rain = less plants = less energy for higher trophic levels
Less rain = less plants = more energy for higher trophic levels
Less rain = less plants = less energy for higher trophic levels
Less rain = more plants = less energy for higher trophic levels
8
In primary succession, lichens and mosses are typically the pioneer species because...
It is the second time organisms are growing in that area
There is lots of soil, just all of the plants were burned down
There was most likely a tornado
There is no soil yet
9
Why are fossil fuels considered non-renewable resources?
They cannot be replaced as quickly as they are being used
They are good for the environment
The can be replaced easily and rapidly
They can be used over and over
10
Birds land on larger animals and eat the insects from their fur. This helps the larger animals and the birds. This is:

Consuming other organisms
18
What are the products of cellular respiration?
Water & Oxygen
Oxygen & Glucose
Carbon Dioxide & Water

Their growth is the same
India
France
20
Which of the following is INCORRECT?
Herbivores eat only primary producers
Heterotrophs make their own food
An organism that eats ONLY insects is a carnivore
Autotrophs obtain food from photosynthesis
21
What factors INCREASE the size of a population?
Birth rate and immigration
Death rate and emigration
Immigration and emigration
Birth rate and death rate
22
Phospholipids make up cell membranes in a bi layer because the "tails" are non-polar and hydrophobic meaning
They LOVE water
Water has nothing to do with this question
They HATE water
They are made of bubbles
23
What is an example of a renewable energy source?
Solar
Wind
Geothermal
All of these
24
Which part of cellular respiration does NOT take place in the mitochondria?
Glycolysis
Krebs Cycle
Electron Transport Chain
Calvin Cycle
25
Why is nitrogen fixation important?
Because atmostpheric nitrogen is not usable by most organisms
Only animals need nitrogen to survive
Only plants need nitrogen to survive
It actually isn't, we can breathe in nitrogen gas from the air
26
What is the monomer (building block) of carbohydrates?
Amino Acids

All cells are made from pre-existing cells
All of these!
30
What is the function of nucleic acids?
To make up cell membranes
To provide energy to cells
