BIOL 1104 Exam 1 Questions And Answers With CompleteSolutions
_____ is the template for _____ to be transcribed into _______,
which are necessary for cell/organism structure, metabolism,
growth, reproduction Correct Answer DNA; RNA; proteins
______ have separate compartments for DNA
replication/transcription, photosynthesis, and energy
transfer/production in each cell Correct Answer Eukaryotes
_______ have genome replication, RNA transcription, energy
production, etc. but are not compartmented Correct Answer
Prokaryotes
"die" Correct Answer a population of individuals disappears
"move" Correct Answer not the same as migration; populations
in good environments can grow to larger population sizes and
spread out; populations in poor environments will begin to
disappear from the effects of environmental stress
(b-d)<0 Correct Answer population decline
(b-d)>0 Correct Answer population growth
1st law of thermodynamics Correct Answer Total amount of
energy in universe is constant
,2 parts of glycolysis Correct Answer 1) prepares glucose for
separation into two three-carbon sugars; ATP is invested into the
molecule during this step to energize the reaction
2) Extracts ATP and high-energy electrons from hydrogen atoms
and attaches them to NAD+. Two ATP molecules
Two ATP molecules invested, four ATP molecules formed by
the end
2 processes of photosynthesis Correct Answer 1) how do we
take energy and store it in chemical bonds (light hits chlorophyll
and we store energy in ATP)
2) Calvin cycle (lowering activation energy by combining
carbon molecules)
2nd law of thermodynamics Correct Answer Every energy
transfer involves some loss of energy in an unusable form, such
as heat
A prediction that many organisms will move their overall
geographic distribution towards cooler habitats is a form of
deductive reasoning. T/F Correct Answer True
acclimation Correct Answer response of an individual; an
individual remodeling itself physically or physiologically;
plasticity associated with physiological and environmental
tolerances
Activation energy Correct Answer initial input of energy
required to start a reaction
, adaptation Correct Answer response of a population;
Adding a phosphate group to AMP (adenosine monophosphate)
or ADP (adenosine diphosphate) is done to:
A) store chemical energy
B) store potential energy
C) release active energy
D) release chemical energy Correct Answer B*
Algae are single-celled Correct Answer Autotrophs and
eukaryotes
Allele Correct Answer one of two or more variants of a gene
that determines a particular trait for a characteristic
Alleles segregate into... Correct Answer Gametes; each gamete
is equally likely to receive one of two alleles (traits) in a diploid
individual
An organism's traits are determined in large part by the genes
inherited from each parent, but also by the ______ that they
experience. Correct Answer environment
Anabolic reactions Correct Answer Build complex molecules
from simpler ones; require energy
Any molecule that absorbs light energy is called a Correct
Answer Pigment
