Nature of Science
Why is it important to repeat an experiment?
To make sure that results were accurate.
The type of Succession that occurs after a fire or flood would be
Secondary Succession
Which type of population distribution occurs when individuals group in patches?
clumped
What atoms make up a molecule of water?
Two hydrogens and one oxygen
Where does the energy come from in an ATP molecule?

Because it is often difficult to gather quantitative (numerical) data, ___________________________ data is collected by using your senses.
qualitative
The first species that shows up in Primary Succession is usually:
Lichens
Which are two ways a population can DECREASE in size?
increase death rate
increase emigration
What type of bond is made by sharing electrons?
Covalent
This happens in cheese, yogurt, and muscles
Lactic Acid Fermentation
A student suggests that a certain species of bacteria grows better in the light than in the dark. The student has 10 culture plates on which to grow the bacteria. Which of the following would be the best experiment to test this idea?
Grow 5 plates in the dark and 5 plates in the light.
The mature populations that occur at the end of succession are called:
climax community
Suppose that a species of toads is introduced into a new environment in an attempt to reduce the population of insects. The toad has no natural predators in the new environment. The toad population would most likely
Exponential growth
An organism’s genetic information is stored in which type of macromolecule?
nucleic acid
This happens in beer, wine, and bread.
Alcoholic Fermentation
The variable in an experiment that changes because you change the independent variable is the
Dependent variable
The simplest grouping of biological organisms that includes both biotic and abiotic factors
Ecosystem
In Rwanda, there are more young children than teenagers, and more teenagers than adults. This age structure indicates a population that do what in twenty years.
Double
The energy needed to get a reaction started is the
Activation Energy
What is NADPH's two jobs in photosynthesis?
Carry Hydrogen and electrons to the Calvin Cycle.
A student suggests that a certain species of bacteria grows better in the light than in the dark. The student has 10 culture plates on which to grow the bacteria. What would be a good hypothesis written in an IF/THEN statement for this experiment?
If I put 5 culture plates in the light and 5 in the dark , Then the ones in the light will grow better.
