specialized in? - correct answer organ system
which sequence correctly lists the different levels of biological organization, from the smallest
and simplest to the largest and most complex? - correct answer cell-tissues-organ-organ
systems-organisms
which statement about an ecosystem is incorrect? - correct answer there is a community of
organisms, but no non-living components
when comparing energy and chemicals in an ecosystem, - correct answer chemicals cycle over
and over again but energy flows through once
all the organisms of carious species living within a given area constitute a(n) - correct answer
community
which of the following is of least importance when concerning the preservation of an
ecosystem? - correct answer preservation of an ecosystem allows humans to exploit as many
resources as possible
the most important factor that determines where major ecosystems are located on the globe is
- correct answer climate
the term biodiversity refers to - correct answer the total number of species, variation of
species, and the ecosystem in which they live
ever since the antibiotic drug penicillin was discovered in 1928, the incidence of resistant
bacteria has steadily increased as a direct result of - correct answer natural selection
as the human population size increases - correct answer biodiversity is adversely affected as
humans have destructive effects on ecosystems
all the banded sunfish in a pond would comprise a(n) - correct answer population
which of the following types of lipids is the most abundant constituent of cell membranes? -
correct answer phospholipid
two molecules of glucose combine to form a disaccharide molecule during a(n) _______
reaction - correct answer dehydration
which of the following is not a function of ATP within the cell? - correct answer all answer
choices are functions of ATP within the cell
which of the following radiation uses is the one that is most likely to have both beneficial and
harmful consequences? - correct answer using radiation to treat a cancer patient
, the backbone of a nucleic acid strand is composed of - correct answer alternating pentose
sugars and phosphate groups
which of these combinations would be found in a nucleotide? - correct answer base-sugar-
phosphate
which of the following reactions is most likely to occur if an individual was to ingest a large dose
of lemon juice? - correct answer there would be an increase in the about of carbonic acid
within the bloodstream. if the carbonic acid didn't form, then the pH of the individual's blood
could shift toward 7.2
In the search to discover the agents that cause mad cow disease, scrapie in sheep, and CJD and
kuru in humans, diseased brain tissues were passed through a fine filter to remove bacteria.
The filtrate was still infectious, indicating that something smaller than bacteria, either viruses or
organic molecules, must be the causative agent. If a virus was responsible for these brain
diseases, then the infectious agent would contain either RNA or DNA. Other possibilities were
that the agent was a carbohydrate, fat, or protein. Tissue filtrates were treated with agents that
destroyed just one of these chemicals and then injected into a healthy animal, with the results
as follows. What is the infectious agent?
•Amylase digests carbohydrates; tissue filtrate still infects healthy test animal.
•Lipase digests fats; tissue filtrate still infects healthy test animal.
•Formaldehyde and/or heat denatures DNA and RNA; tissue filtr - correct answer protein
which is not a correct attribute of a metabolic pathway? - correct answer a constant supply of
new enzymes must be produces to keep the metabolic pathway active
whether or not an enzyme is active and present within a cell depends on all of the following
except - correct answer whether the enzyme catalyzes an endergonic or exergonic reaction
the location in which the enzyme and substrate complexes is called the - correct answer active
site
where within the cell is ATP built up? - correct answer mitochondria
which of the following is a by-product of photosynthesis? - correct answer oxygen
how efficient is the breakdown of one glucose via cellular respiration? - correct answer 39%
why does FADH2 result in fewer ATP than NADH + H+ - correct answer FADH2 drops its
electrons off lower on the electron transport chain
why is cellular respiration organized into four phases? - correct answer so that the energy
within the glucose molecule can be released in a stepwise fashion
