Flashcards in Chapter 1 - Science of Biology Deck (30):
Characteristics shared by living systems
Cellular organization, ordered complexity, sensitivity, growth, development, and reproduction, energy utilization, homeostasis, evolutionary adaptation.
Cellular level: Atoms, molecules, organelles, cells
Organismal level: tissues, organs, organ systems
Population level: population, species, biological community
Biosphere: entire planet
Replace general principles to protect specific results.reasoning of mathematics and philosophy, and is used to test validity of general ideas.
Logic flows from specific to general. Uses specific observations to construct general scientific principles.
One variable is altered in a known way to test a particular hypothesis
Variable is left unaltered
Philosophical approach that breaks larger systems into their component parts.
Bones that have the same evolutionary origin, but now different structure and function
Structures that have similar function but different evolutionary origins. Eg: butterfly and bird wings
Represents the evolutionary history of the Dean, it's family tree.
All living organisms consist of cells. Biologists schleidsn and Schwann. All cells come from pre existing cells
Deoxyribonucleic acid. Formed from two long chains of building blocks, called nucleotides. Four different nucleotides are found in DNA and sequence in which they occur encode cells information
Specific sequences of several hundred too many thousand nucleotides make up a gene, a discrete unit of information
The maintenance of a relatively stable internal physiological environment and an organism;usually involves some form of feedback self-regulation
And extremely large biological molecule; refers specifically to proteins, nucleic acid, polysaccharides, lipids and complexes of these.
Specialized part of cell
Any group of individuals, usually of a single species, occupying a given area at the same time
Have cell walls of chitin and obtain energy by secreting digestive enzymes and then absorbing products released from the environment
Luck so walls and obtain energy by ingesting other organisms
Consists of all single so eukaryotes except yeasts. Also multicellular algae
Have cell walls of cellulose and obtain energy by photosynthesis
Smallest unit of an element that contains all the characteristics of that element
Group of similar cells are organized into a structural and functional unit
A bacterium; a cell lacking a membrane – bound nucleus or membrane – bound organelles
A cell characterized by membrane-bound organelles, most notably the nucleus, and one that possesses chromosomes who's DNA is associated with proteins; an organism composed of such cells
Effect environment has on a variable population, such that the best adapted individuals reproduce and survive at a higher rate
3 domains of living things
Archaea, bacteria, eukarya
Kingdoms of eukarya
Bacteria, Protista, Animalia, plantae
3 factors that influence extent to which Chem reactions occur
Catalysts, temps, concentration, surface area, reactants
