BSC 1010C Exam 1 Questions With Complete Solutions
.
The experiments of Wohler, Kolbe, Miller, and other chemists
invalidated the concept of vitalism by demonstrating that
Correct Answers Organic molecules could be produced apart
from living organisms using inorganic materials
A compound contains hydroxyl groups as its predominant
functional group. Therefore this compound Correct Answers
Should dissolve in water
A controlled experiment is one that Correct Answers Tests
experimental and control groups in parallel
A covalent bond is likely to be polar when Correct Answers
One of the atoms sharing electrons is more electronegative than
the other atom
A covalent chemical bond is one in which Correct Answers
Outer shell electrons of two atoms are shared so as to
satisfactorily fill their respective orbitals
A friend of yours calls to say that his car would not start this
morning. He asks for your help. You say that you think the
battery must be dead. If so, then jump-starting the car from a
good battery will solve the problem. In doing so, you are Correct
Answers Stating a hypothesis and using that hypothesis to make
a testable prediction
, A hydrocarbon skeleton is covalently bonded to an amino group
at one end and a carboxyl group at the other end. When placed
in water this molecule would function Correct Answers As an
acid and a base
A localized group of organisms that belong to the same species
is called a ? Correct Answers Population
A slice of pizza has 500 kcal. If we could burn the pizza and use
all the heat to warm a 50-L container of cold water, what would
be the approximate increase in the temperature of the water?
Correct Answers 10 deg C
Agrobacterium infects plants and causes them to form tumors.
You are asked to determine how long a plant must be exposed to
these bacteria to become infected. Which of the following
experiments will provide the best data to address that question?
Correct Answers Measure the number of tumors formed on
plants, which are exposed to Agrobacterium for different lengths
of time
Agrobacterium infects plants and causes them to form tumors.
You determine that tumor formation requires a large amount of
the plant's energy for tissue formation. How might this change
the number of offspring a plant produces, and what is the most
likely explanation for this change? Correct Answers The
number of offspring should decrease, because the plant will
divert energy, from reproduction to tumor formation
Bonds between two atoms that are equally electronegative are
Correct Answers Nonpolar covalent bonds
