Principles of Biology test 1 UPDATED
ACTUAL Exam Questions and CORRECT
Answers
The fundamental organizing principle of biology and core theme is __________. - CORRECT
ANSWER - evolution
The use of energy by living organisms __________. - CORRECT ANSWER - involves
chemical cycling from light energy from the sun for the production of chemical energy in food to
the decomposition and the returning of chemicals to the cycle
Natural selection tends to act at which of the following levels? - CORRECT ANSWER -
population
Using models that represented camouflaged and non-camouflaged mice, Hoekstra and her
students tested the hypothesis that coloration of beach and inland mice provides camouflage that
protects them from predation.
Regardless of whether the models were placed in the beach or the inland habitat, the
camouflaged model always acted as the __________ group. - CORRECT ANSWER -
control
Feedback regulation includes __________ - CORRECT ANSWER - both negative
feedback where the pathway shuts down and positive feedback where the pathway speeds up
Some properties and processes that are associated with life include all of the following except
_____________ - CORRECT ANSWER - reductionism
How is the information encoded in DNA actually used by organisms? - CORRECT
ANSWER - The information in DNA is transcribed to RNA and then translated into
protein.
, With evolution as the core theme of biology, we can explain traits shared by organisms as
evidence of __________ and traits that differ among organisms as evidence of __________. -
CORRECT ANSWER - descent from a common ancestor; adaptation through natural
selection
A scientific theory is __________. - CORRECT ANSWER - a well-supported concept that
has broad explanatory power

selection as a mechanism for evolution? - CORRECT ANSWER - Darwin synthesized his
theory of natural selection from all of the listed observations and inferences.
The units of inheritance are called __________. - CORRECT ANSWER - genes
The concept of "descent with modification" was proposed by __________ - CORRECT
ANSWER - Charles Darwin
Regulation of molecules within an organism in response to a changing level of chemicals and the
ability to self-regulate is called __________. - CORRECT ANSWER - feedback regulation
The process that directs the manufacture of a cell product from a gene is called __________. -
