FAU BROOKS BIODIVERSITY UNIT 1 EXAM QUESTIONS WITH COMPLETE
SOLUTIONS GUARANTEED PASS BRA, Exams of Advanced Education
Evolution facts - ANSWER-evolution has leed to an explosion of life on Earth
-evolution of life affected by the changing Earth (plate tectonics, ice ages, sea
level, etc.)
-record of life & Earth's history is found in rocks (geology, era, periods)
Evolution Definition - ANSWERis the concept that all given organisms are
related to each other through common ancestry
Have scientists proven how llife has arisen? - ANSWERNo.
How Life MIGHT have arisen - ANSWER-scientists speculate the universe
began around 13-14 billion years ago via the Big Bang Theory
-Earth was formed around 4.6 billion years ago
-life started around 3.5 bya from fossil evidence
Big Bang Theory - ANSWERtheory of how the universe formed 16-18 billion
years ago
, Haldane-Oparin Hypothesis - ANSWER-two scientists who proposed the
theory that life arose via biochemical processes aka chemical evolution
Life arose spontaneously from methane, ammonia, water & energy sources -
ANSWER-simple molecules containing some of the elements of life, CHON,
could combine to form the building blocks of complex molecules found in
organisms
-life could have eventually risen from this "primordial soup" of organic
compounds
Primordial Soup - ANSWERis a hypothesis that the first organisms were
heterotrophs because they consumed the abundant food molecules present
in the atmosphere
Heterotroph - ANSWERorganisms that are nourished from outside sources
hetero = different
troph = nourishment
Miller-Urey Experiment - ANSWER-tested the Haldane-Oparin theory and
discovered that organic molecules could be synthesized in lab situations that
simulated conditions on early Earth.
-contemporary scientists think that methane and ammonia were likely absent
in early atmosphere
-more likely CO, CO2, H2, N2, & H20
Panspermia - ANSWERtheory that rocks from outer space provided organic
materials (& possibly microorganisms) that could also have been the catalyst
for life to develop on Earth
