ANSWERS 2024
Hiearchy of life order - correct answers-bio-eco-com-pop-organism-organ syst-organ-
tissue-cell-organelle-molecule-atom /each step causes new properties to emerge as
result of interaction among lower level components
Systems biology - correct answers-model dynamic behavior of a whole biological
systems based on a study of interactions among systems parts
Reductionism - correct answers-complex systems broken down to simpler components
that are more manageable to study
Energy - correct answers-energy from sunlight-converted to chemical energy by
producers-passed to consumers
Cell - correct answers-organisms basic unit of structure and function
Eukaryotic cells - correct answers-contain membrane-enclosed organelles including
dna-containing nucleus
Prokaryotic cells - correct answers-lack dna containing nucleus or membrane
DNA - correct answers-long linear polymer in the nucleus of cell formed from
nucleotides and shaped like a double helix transfers heritable info from parents to
offspring
Gene expression - correct answers-conversion of the information encoded in a gene
first into messenger RNA and then to a protein

or among different species
Positive feedback - correct answers-Feedback that tends to magnify a process or
increase its output. Regulation common to life at all levels which regulate biological
systems
, Natural selection - correct answers-the principle that, among the range of inherited trait
variations, those that lead to increased reproduction and survival will most likely be
passed on to succeeding generations
Inquiry - correct answers-scientists make observations by collecting data

Hypothesis - correct answers-a proposal intended to explain certain facts or
observations
Deductive reasoning - correct answers-predictions that can be used to test hypotheses
made from inductive reasoning

by testing control groups and experimental groups that differ in only that one variable
Scientific theory - correct answers-generated new hypotheses that is supported by large
body of evidence

Population - correct answers-set of organisms of the same spieces
Community - correct answers-consists of populations of various species inhabiting a
specific area
Ecosystem - correct answers-consists of a biological community along with the nonliving
factors important to life
Biosphere - correct answers-made up of all earth's ecosystems
