Reductionism involves reducing complex systems to simpler components as a way to understand how the system works. Systems biology describes research works on the opposite - complex interactions, or attempting to see the whole picture. Discovery-based

Origin of Species
Taxonomists/systematists work with the identification, nomenclature, and classification of species.
Practical: the unit is considered a species by a competent taxonomist Morphological: similar morphologies Problems

Population genetics emerged as a branch of genetics in the 1920s and 30s. A population is a group of interbreeding individuals. Polymorphic genes (literally "many-formed") are commonly present as two monomorphic genes exist predominantly ( 99 %) as a

History of Genetics
Early geneticists thought organisms changed in huge leaps (they were called mutationists), while evolutionary biologists, who believed in a slower process, were called
Name all possible species concepts gone over in class and in the book, and describe each and its problems.
Practical: considered a species by a "competent taxonomist". Problem: what do you mean by Morphological: looks mean everything. Problems: conve
1. What is the difference between accuracy and precision?
Accuracy refers to how close you are to a standard value where precision refers to how close
your measurements are to each other
2. Would not using a primary standard grade reagent af
