BIO 100- BIOLOGY CONCEPTS QUESTIONS AND ANSWERS
Scientific Method - CORRECT ANSWER✅✅✅A logical, systematic approach to the solution of a
scientific problem
1. Make observations
2.Make hypothesis
3.Test hypothesis
Are the results consistent with the hypothesis? If yes, fail to reject hypothesis. If no, reject hypothesis
Theory - CORRECT ANSWER✅✅✅A hypothesis that has been tested many times but never
disproved. A high level of confidence but can never truly prove that it is absolute truth
Spontaneous Generation (Redi) - CORRECT ANSWER✅✅✅The idea that you can create living things
out of non living things. (Legless worms come from flies)
Theory of Biogenesis - CORRECT ANSWER✅✅✅the idea that living things can only arise from other
living things
4 elements living things are made of - CORRECT ANSWER✅✅✅Carbon, Hydrogen, Oxygen, Nitrogen
Vitalism - CORRECT ANSWER✅✅✅The idea that living things have a vital or life force that they can
only obtain from other living things
Mechanism - CORRECT ANSWER✅✅✅Living things are complex biological machines . "It's not what
you're made of but how you're organized"
Characteristics of Life - CORRECT ANSWER✅✅✅1. Made of cells- constant internal environment
2. All living things are highly organized
3. Obtain energy from the environment, then transform it —- organization, produce heat, growth,
reproduction and movement
4. Sense environment and react to it
, 5. Develop in complex ways over time, not just grow
6. Reproduce offspring similar to themselves
7. Store information in DNA
8. Evolve and become adapted to their environment
***Viruses have 7 out of these 8 characteristics but are not made of cells
Chemistry - CORRECT ANSWER✅✅✅The study of matter - all matter is made up of a few elements &
made up of atoms
Elements - CORRECT ANSWER✅✅✅any substance that cannot be broken down into simpler
substances, simplest forms of matter
Atoms - CORRECT ANSWER✅✅✅Simplest form of an element
Proton: positive electrical charge
Neutrons: no electrical charge
Electrons: negative electrical charge
Nucleus - CORRECT ANSWER✅✅✅Control center of the cell - protons and neutrons of an atom and
electrons orbit the nucleus
Atomic Number - CORRECT ANSWER✅✅✅the number of protons in atoms of an element (red on
periodic table, whole #)
Atomic Mass (amu) - CORRECT ANSWER✅✅✅the number of protons plus the number of neutrons
(black # on periodic table)
Atomic Mass - Atomic Number - CORRECT ANSWER✅✅✅number of neutrons
Isotope - CORRECT ANSWER✅✅✅Atoms of the same element with different numbers of neutrons
