◎ ribosomes are a universally present organelle in all cells and are primarily composed
of which of the following molecules? ANSWER:- RNA and proteins
◎ the formation of new elements of the periodic table occurred by the fusion of
preexisting combinations of proteins and neutrons during the Big Band and within dying
stars known as Supernova? ANSWER:- true
◎ an experimental study is conducted to determine whether or not 10 milligrams of the
drug somatostatin can overcome the effect of dwarfism in humans. The change in
height of the participants in the clinical trial represent the? ANSWER:- dependent
variable
◎ an inquiry based research approach in biology includes? ANSWER:- choose this
answer if all of the above aspects on inquiry based research in biology
◎ a stable, non-radioactive element is known to have an atomic number of 12,
therefore its atomic mass would be? ANSWER:- 24
◎ the half life of radioactive carbon 14C is 5,730 years. A sample of fossilized wood is
shown to contain only 6.35% radioactive 14C compared with the amount of radioactive
14C in living wood samples of today, thus the age of the fossilized would be closest to
which of the following? ANSWER:- 22,920
◎ of the following known facts which would provide some of the strongest evidence for
a common ancestry of all known cellular life? ANSWER:- the universality of the genetic
code
, ◎ the type of error occurring in scientific experiments that is due to the intrinsic
measurement and/or resolution of an instrument is referred to as? ANSWER:- random
error
◎ Robert Hazen's lab proposed that minerals might have played a role in allowing early
primitive organic molecules to react with each other chemically forming more complex
molecules primarily by? ANSWER:- by providing scaffolding support to facilitate
concentration
◎ one of the most effective ways of presenting numerical data from a clinical trial would
likely be a? ANSWER:- table

ANSWER:- a condensation reaction
◎ homochiral polymeric molecule, such as proteins that occur in living cells today, are
composed of? ANSWER:- only one of two possible optical isomers of amino acids
◎ thermophilic bacteria, which might have been an initial LUGA, have been
hypothesized to have arisen? ANSWER:- around deep ocean hydrothermal vents
◎ the type of chemical reaction acting upon the polymer shown in the figure below
might best be described as? ANSWER:- a hydrolysis reaction
◎ which of the following is likely to be a step within the scientific method in biology?
ANSWER:- all of these can be a part of the scientific method
◎ the scientific method involves the construction of knowledge based upon
observation, testing, and measurement. Identify among these statements the one that
can NOT be experimentally based? ANSWER:- choose this answer if all the above
statements are experimentally based
◎ a hypothesis that has been confirmed through repeated experimental tests over a
very long period of time may be referred to as? ANSWER:- a theory
◎ which of the following phrases better describes the results of natural selection?
ANSWER:- the changes in inherited characteristics of a population

ago by using the technique of Molecular Clock Dating which compares DNA sequence
differences as species diverge? ANSWER:- true
