BIO 1150 Exam 1 study guide questions
with correct answers
What is biology? - CORRECT ANSWER✔✔-Science that studies living
| | | | | | | | |
things (biotic) and the non-living things (abiotic) they interact with.
| | | | | | | | |
What is life? What are the 7 basic characteristics of all living things? -
| | | | | | | | | | | | | |
CORRECT ANSWER✔✔-1. Composed of cells
| | | |
2. Contain molecules of life (nucleic acid, protein, carbohydrates, lipids)
| | | | | | | | |
3. Capable of reproduction
| | |
4. Use energy and raw material to fuel metabolism
| | | | | | | |
5. Respond to the environment
| | | |
6. Maintain homeostasis
| |
7. Adaptive traits they allow you to survive and evolve
| | | | | | | | |
What is a virus? Is it alive? Why or why not? - CORRECT ANSWER✔✔-A
| | | | | | | | | | | | | |
complex protein that possesses its own genes in the form of RNA and
| | | | | | | | | | | | |
DNA molecules. Whether or not it is alive is a grey area because it must
| | | | | | | | | | | | | | |
infect a host cell to metabolize nutrients and reproduce itself, however
| | | | | | | | | | |
it can still evolve and reproduce itself.
| | | | | |
, What are the 3 domains of life? What are characteristics of each? Which
| | | | | | | | | | | |
do humans fall into? - CORRECT ANSWER✔✔-Bacteria: Unicellular
| | | | | | | | |
prokaryotic organisms. | |
Archaea: unicellular prokaryotic organisms that tend to live in extremely
| | | | | | | | |
harsh environments.
| | |
Eukaryea:Eukaryotic cells that contain a membrane bound nucleus | | | | | | | |
(these are what humans have in their bodies).
| | | | | | |
Be able to identify a good hypothesis and determine what makes a good
| | | | | | | | | | | |
scientific hypothesis - CORRECT ANSWER✔✔-Should be a statement.
| | | | | | | | |
Can be sown to be false, it can never be proved to be true. Testable.
| | | | | | | | | | | | | | |
Gain knowledge. If-then statement.
| | |
What are the steps of the scientific method? - CORRECT ANSWER✔✔-
| | | | | | | | | |
Make observation, develop hypotheses, make prediction, test prediction
| | | | | | |
(experiment), if the evidence supports hypotheses keep testing, if not
| | | | | | | | | | |
go back and revise hypotheses.
| | | |
How is a Theory different than a hypothesis? - CORRECT ANSWER✔✔-A
| | | | | | | | | | |
theory is a collection of hypotheses which have been tested numerous
| | | | | | | | | | |
times, have large amounts of data and evidence in support of them, and
| | | | | | | | | | | |
|are extremely unlikely to change.
