A major unifying concept of biology is?
Answers:a.
that cells are unique and require different laws ofbioenergetics to function in the physical
universe
b.
the theory of Panspermia (Life originated extraterrestrially)
c.
the Cell Theory
d.
life arose spontatenously
e.
choose this choice if all of the above are major unifying biological concepts correct answers
Selected Answer:a.
cell theory
Response Feedback:
All cell use the same physical laws of the Universe.There are no laws unique to life alone.
The Theory of Panspermia is that life arose elsewherein the Universe, but there is no physical
evidence to support that.
Most evidence suggest Life arose slowly via increasing chemicalcomplexity that lead to an
emergent property we descibe as life.
What is an emergent property?
Answers:a.
Random reactions which release energy from stored carbon compounds
b.
Unexpected, nontrival properties of simplier components that arise from complexity
c.
Only endergonic (energy requiring) reactions which expend energy driving other reactions
d.
, Reactions that use energy and materials from the environment tosynthesize cellular
components and do metabolic work
e.
none of the above is correctly describes emergent properties correct answers Selected
Answer:b.
Unexpected, nontrival properties of simplier components that arise from complexity
Emergent properties are those processes that cells perform that arenot necessarily predictable
based upon the unique properties ofthe individual components and/or reactions in the system.

Answers:
Antony van Leeuwenhoek
Marcello Malphigi
Theodor Schwann
Rudolph Virchow
Matthais Schleiden correct answers Selected Answer:
Rudolph Virchow
Rudolph Virchow is credited with being among the first to stateOmnis cellula e cellula, "all
cells come from cells", which he published in 1855,which today is a major paradigm of
biology.
The scientific method involves the construction of knowledge based upon observation,
