What is an alcohol? - ANSWERS-An organic compound characterized by the presence of a
hydroxyl functional group; -OH.
True or False: Avogadro's number acts as the conversion factor for converting between the
number of moles in a sample and the number of molecules in the sample. - ANSWERS-True.
Since 12-C's molar mass is 12 grams, 48 grams of 12-C atoms would be equal to ____ moles. -
ANSWERS-4.
The International Committee for Weights and Measures (ICWM) defines one mole as the
number of atoms in exactly: - ANSWERS-12g of Carbon-12.
Molar mass is a numerical value that represents ______. - ANSWERS-The mass of a substance
divided by the amount of that substance.
True or False: An element's molar mass and atomic weight are always equal. - ANSWERS-False.
One mole of boron is equivalent to how many grams? - ANSWERS-10.81 g.
,The mass of one mole of water is: - ANSWERS-18.02 g.
The amount of a substance equal in grams to the sum of the atomic masses is a(n): - ANSWERS-
Mole.
The mass in grams of one mole of oxygen gas is: - ANSWERS-32 g.
3.42 moles of CaO is equivalent to: - ANSWERS-192 g CaO.
Most of the cell membrane's specific functions are controlled by: - ANSWERS-Proteins
Alcoholic Fermentation is a form of: - ANSWERS-Anaerobic Respiration
Phagocytosis is a form of: - ANSWERS-Endocytosis
What is a pyruvate? - ANSWERS-Pyruvate is an important chemical compound in biochemistry.
It is the output of the metabolism of glucose known as glycolysis. One molecule of glucose
breaks down into two molecules of pyruvate, which are then used to provide further energy, in
one of two ways.
What are the small spherical bodies within a cell where proteins are assembled according to
genetic instructions? - ANSWERS-Ribosomes
What is the structural and functional unit of life? - ANSWERS-The cell
, What is a prokaryotic cell? - ANSWERS-A cell that lacks a true nucleus and membrane-bound
organelles
What is a eukaryotic cell? - ANSWERS-A cell that contains a nucleus and membrane-bound
organelles
What is cellular respiration? - ANSWERS-A catabolic pathway for the production of ATP, in which
sometimes oxygen is consumed as a reactant along with an organic fuel. At times, the process
proceeds without oxygen, but this is less efficient.
What is anaerobic respiration? - ANSWERS-A form of cellular respiration that does not involve
oxygen.
What is aerobic respiration? - ANSWERS-Form of cellular respiration which requires oxygen to
generate energy.
Name the four types of transport that allow small molecules to move across the cell membrane:
- ANSWERS-Diffusion, Osmosis, Active Transport, and Passive Transport.
Prokaryotes often reproduce by: - ANSWERS-Binary Fission
What is binary fission? - ANSWERS-A form of asexual reproduction in which the parent divides
into two identical halves.
What is cytokinesis? - ANSWERS-The division of cytoplasm into two identical daughter cells,
which occurs during the telophase stage of mitosis.
What is a haploid cell? - ANSWERS-A cell that contains one set of chromosomes
What is an alcohol? - ANSWERS-An organic compound characterized by the presence of a
hydroxyl functional group; -OH.
