BIOS 120 EXAM 1 questions n correct
answers rated A+
relationship between ecology and evolution - correct answer ✔✔ -ecology is the scientific study
of the distribution and abundance of organisms and their interactions with the environment
relationship between ecology and evolution - correct answer ✔✔ the mechanisms that drive
evolution are fundamentally ecological, and the participants in ecological interactions are
products of evolution.
relationship between ecology and evolution - correct answer ✔✔ They provide an answer to
the question of why there are so many species are out there, as well as an answer to the
question of why they take the forms they do.
Fundamental properties of life - correct answer ✔✔ Organization and information:
-an important part in organization is homeostasis which allows for the regulation of internal
environments.
-Maintaining a constant internal environment through constant changes is called allostasis
(mechanism is adaptation)
-DNA is the template for life's information
Fundamental properties of life - correct answer ✔✔ Need for an energy source:
-This is because life is an open thermodynamic system
-As humans, our energy comes from us being heterotrophs; we rely on other organisms for
energy
-Autotrophs and chemoautotrophs get their energy from sunlight
, Fundamental properties of life - correct answer ✔✔ Reproduction and Evolution:
-All living things have the ability to make copies of themselves
Scientific Method - correct answer ✔✔ Observation, Hypothesis, Experimentation, Data
Analysis, and Conclusion.
Scientific Method - correct answer ✔✔ Karl Popper advanced the most modern view of the
scientific method - emphasizing that all hypotheses must be falsifiable
Scientific Method - correct answer ✔✔ Scientific Paradigms - the underlying understanding that
explains out natural world. Limits some ideas but also leads to more future research. Some
paradigms have been reshaped due to new ways of thinking and discoveries.
Origin of life - correct answer ✔✔ Is an unsolved mystery in science.
Origin of life - correct answer ✔✔ A non-supernatural hypothesis for the origin were advanced
by Alexsandr Oparin in 1922.
Origin of life - correct answer ✔✔ Alexsandr:
-He proposed that molecules in the early atmosphere interacted with energy sources such as
lightning, UV light, or hydrothermal energy, to produce the first biomolecules. He proposed the
idea of "organic soup"
-Oparin's model of the early atmosphere is unlikely-it is now considered more likely that life
originated in hydrothermal vent areas
-1903 Svante Arrhenius proposed a hypothesis that microbes from interstellar space
"inoculated" the Earth
Mechanisms of speciation - correct answer ✔✔ Speciation: the origin of new species. With
extinction, it is one of two keystone processes of macroevolution.
