BIO 111 EXAM 1 (CHAPTERS 1-4) TEST QUESTIONS WITH ACCURATE SOLUTIONS
Why is natural selection considered a "mechanism" of evolution?
It works as a process
Inductive Logic
Goes from particular instances to a general premise; Conclusions are no usually certain
Deductive Logic
Goes from a general premise to particular instances
Scientific Method
1. Observe
2. Make a hypothesis
3. Make a prediction on what will happen if hypothesis is proved
4. Conduct experiment
5. Analyze your data
Independent Variable
The factor of interest
,Dependent Variables
The outcome/response
Control Group
Receives all conditions except the factor of interest
Comparative Groups
Comparing levels of independent variable
What is the difference between a hypothesis and a theory?
A hypothesis is a tentative explanation for an observable phenomenon, a theory is a set of
ideas that explain things broadly and is supported by lots of evidence
what are the roles of comparative and control groups in an experiment?
Comparative compares the results from two or more versions of the independent variable.
Control groups is used to determine if the independent variable is the cause of the results.
Matter
Takes up space and has mass
What are the three states of matter?
, Solids, liquids, gases
Element
Substances that can't be broken down by chemical reactions
What is the basic unit of matter?
Elements
What are the four elements that make up ~96% of living things?
Carbon, Hydrogen, Nitrogen, Oxygen ("CHNO")
What is the difference between and element and an atom?
An element is a substance that can't be broken down by chemical reactions, an atom is the
fundamental unit of an element.
What are the three subatomic particles that make up atoms?
Nucleus, Shells, and Electrons
Atomic Number
The number of protons
