chapter one Flashcards
themes in the study of life
evolutionary adaptation
adapt heritable traits that are best suited to their environment
regulation
maintain constant body temperature with blood regulation
eukaryotic
contains membrane enclosed organelles, ex: nucleus
prokaryotic
lacks a nucleus or other membrane enclosed organelles, ex: bacteria
genes
discrete unit of hereditary info consisting of a DNA sequence specific for a trait
genomics
study of whole sets of genes and their interactions
proteomics
study of protein sets and their properties
bioinformatics
use of computational tools to store the volume of data that results from high throughput methods
domain: archea
single celled prokaryotic organisms, multiple kingdoms that live in Earths extreme environments
domain: bacteria
single celled prokaryotic organisms, most widespread and diverse prokaryotes and classified into kingdoms
darwin and natural selection
a process in which individuals that have certain inherited traits tend to survive and reproduce at higher rates
null
there is no statistical difference
alternative
there is a difference, test to reject the null
control group
baseline, subjects that lack the specific factor being tested
experimental group
has one variable (independent), set of subjects that receives the specific factor being tested in a controlled experiment
independent variable
factor being manipulated
dependent variable
result, factor predicted to be affected by the independent variable
the question science cannot answer
the supernatural world
theory
subject to change, evolve, why things happen?
law
doesn’t change, something will happen and does
biosphere
consists of all life on Earth and all places where life exists, bodies of water and land
producers
produces organic compounds from carbon dioxide by photosynthesis
consumers
an organism that feeds on other organisms or their remains
analogies
similar function
homologies
similar embryonic origin
