Unit 1 Exam Flashcards
Biology
The scientific study of life
Genetic Expression
Process that converts gene to cellular product
Genomics
Study of sets of genes in one or more species
Systems Biology
Interactions among parts of a biological system
Emergent Properties
Properties resulting from the arrangement and interactions as complexity increases
Bioinformatics
Use of computational tools to process a large amount of data rapidly
Proteomics
Study of whole sets of proteins
Consumers
Organisms that feed on other organisms
4 base pairs that make up DNA
Adenine, cytosine, guanine, thymine; A+T, C+G
Smallest –> Largest
Nitrogenous base, double helix, chromatid, chromosome, organelle, cell, tissue, organ, organ system, individual, population, community, ecosystem, biosphere
Eukaryotic vs Prokaryote
Eukaryote - nucleus, membrane, large
Prokaryote - no nucleus, no membrane, smaller
Feedback regulation
Response to stimulus
amount of product regulates process as a whole
Positive vs negative feedback
positive - end process speeds up process
negative - response/ amount of product will slow down process as a whole
Evolution account for the ___ and ___ of life
unity, diversity
Did we evolve from monkeys?
No! common ancestor
Three domains of life:
bacteria, archea, eukarya
4 subgroups: plants, fungi, animals, protists(most diverse and numerous)
Inductive vs. deductive reasoning
inductive - large number of specific observations -> generalization
deductive - general premise -> specific predictions
independent variable
manipulated by only the researcher
dependent variable
variable affected by change in independent variable.
Name for humans?
Homo sapiens
Naming system to name species
binomial naming system 1.Genus 2.Species name
Darwins observations
- Overproduction
- Adaptation
- Variation
Natural Selection
individuals with traits that are best suited to their environment are more likely to survive and reproduce
Do individuals or populations evolve?
populations
