Bio- Chapter 1 Flashcards
Biology
The scientific study of life
Science
Is an approach to understanding the natural world that is based on injury- a search for information, explanations, and answers to specific questions
Discovery Science
Describing nature, Verifiable observations and measurements are the data of this.
Hypothesis-driven science
Explaining nature
Data
Recorded observations, these are items of information on which scientific inquiry is based on.
Scientific Method
This consists of a series of steps. Observation, question, hypothesis, prediction, experiment.
Hypothesis
Tentative answer to a question, a proposed explanation for a set of observations.
Theory
Is much broader in scope than a hypothesis. This is a comprehensive explanation supported by abundant evidence, and it is general enough to spin off many new testable hypotheses.
Properties of life
Order, regulation, growth and development, energy processing, response to the environment, reproduction, and evolution.
Species
Generally defined as a group of organisms that live in the same place and time and have the potential to interbreed with one another in nature to produce a healthy offspring.
Taxonomy
The branch of biology that names and classifies species, is the arrangement of species into a hierarchy of broader and broader groups.
Three domains of life
Bacteria, Archaea, and Eukarya
What do Bacteria and Archaea have in common?
They both have prokaryotic cells- that is relativity small and simple cells that lack a nucleus or other compartments bounded by internal membranes.
Eukaryotes
Organisms with eukaryotic cells- that is relatively large and complex cells that contain a nucleus and other membrane-enclosed compartments, are grouped into the domain of Eukarya.
Plantae, Fungi, and Animalia are classified under
Eukarya
