BIOL 115 Exam Questions With All
Correct Answers A+ Pass
levels of organization of life - CORRECT ANSWER-atom, molecule, cell, tissue,
organ, organism, population, community, ecosystem, biosphere
5 functional traits of life - CORRECT ANSWER-growth, reproduction,
homeostasis, sensation/response to stimuli, obtaining/use of energy
3 domains of life - CORRECT ANSWER-bacteria, archaea, eukarya
eukarya - CORRECT ANSWER-eukaryotes (with nucleus), heterotrophs; ex)
animals, plants, fungi, protists
bacteria - CORRECT ANSWER-unicellular, prokaryotes (no nucleus or
organelles), protein-based cell walls, mostly heterotrophs
archaea - CORRECT ANSWER-extremophiles, unicellular, prokaryotes (no
nucleus or organelles), some autotrophic, some chemotrophic
viruses - CORRECT ANSWER-NOT life, require host cell to replicate
, prions - CORRECT ANSWER-proteins with pathogenic folding patterns that can
be perpetual
viroids - CORRECT ANSWER-nucleic acids (RNA) that can replicate in host
cell theory - CORRECT ANSWER-cells are the smallest independent unit of life,
all living things are made of cells, cells are formed by the reproduction of existing
cells

nucleic acids
carbohydrates - CORRECT ANSWER-monosaccharides (one sugar, glucose),
disaccharides (two molecules, sucrose), polysaccharides (chains of
monosaccharides)
proteins - CORRECT ANSWER-chains of amino acids; roles include structure,
facilitating chemical reactions (enzymes), signaling between cells, transport,
movement at cellular level
amino acids - CORRECT ANSWER-central carbon bound to amino group,
