BIOL 3204 Exam 1 Questions With
Correct Answers
Characteristics of Science: CONPTT - ANSWER Consistent= repeatable
Observable= evidence occurrence can be observed
Natural= Cause or mechanism can be demonstrated
Predictive= the natural cause can be used to make predictions
Testable= these predictions are testable (hypotheses)
Tentative= subject to modification upon additional studies
Science should be
A) directly observable
B) unpredictable
C) definitive
D) repeatable - ANSWER D) repeatable
Comparative approach
Current physiology represents 4 billion years of evolution - ANSWER 1. Ask
similar questions of multiple species in order to determine shared vs. unique
traits
2. When mapped on a phylogenetic tree, pattern tells us if trait evolved once or
multiple times
Biomolecules - ANSWER Molecules of biological importance
Contain carbon atoms
synthesized by living organisms
the "currency" of energy and growth= metabolism
Few small inorganic molecules - ANSWER Water, salts, acids, bases and gasses
Four classes of macromolecules - ANSWER Carbohydrates
Lipids
Proteins
Nucleic acids
The central dogma of molecular biology - ANSWER -Flow if genetic information
-Expression of genetic variation into phenotypic variation
-Functional roles of non-coding RNAs and other regulatory mechanisms
continue to be characterized
How to regulate metabolism - ANSWER 1. control enzyme concentrations
