Unit 1- Biol 230 Athabasca Questions With
Complete Solutions
A solution with more Hydrogen would considered
basic or acid and would be greater or lesser than
7? Correct Answers A solution with more
hydrogen (+) would be more acid and be less than
7.
A solution with more OH- than H+ would be
considered basic or acidic and would be greater or
lesser than 7? Correct Answers a solution with
more OH- would be more basic and would fall
greater than 7 on the Ph scale.
A triglyceride that is liquid at room temperature is
considered to be... Correct Answers An Oil
A triglyceride that is solid at room temperature is
considered a... Correct Answers fat
A valence shell that is chemically stable Correct
Answers has 8 electrons and is unlikely to form
other bonds with other atoms
Adenosine Triphosphate (ATP) Correct Answers
one of the principal chemical compounds that
living things use to store and release energy. Our
"Energy Currency"
,Adrenocortical hormones Correct Answers Help
regulate metabolism, resistance to stress, and salt
and water balance.
Amphiphatic Correct Answers A chemical or
molecule that has a hydrophilic head and
hydrophobic tail used to transport fat.
They line up tail to tail in a double row to make up
membranes
Anion Correct Answers A negatively charged ion
Atomic Number Correct Answers total number of
protons in an atom
atomic weight/mass Correct Answers the atomic
mass of an elementis close to the mass number of
its most abundant isotope.
Baroreceptors: Correct Answers the receptors),
pressure sensitive neurons located in the walls of
certain blood vessels, detect the higher pressure.
These neurons send action potentials (input) to the
brain (control center)
bile salts Correct Answers cholesterol derivatives
that function in fat emulsification and absorption
, Carbohydrates Correct Answers include sugars,
glycogen, starches, and cellulose
-Function mainly as a source of chemical energy
for generating ATP
carbonic acid-bicarbonate buffer system. Correct
Answers Carbonic acid (H2CO3) can act as a
weakacid, and the bicarbonate ion (HCO3−) can act
as a weak base. Hence,this buf er system can
compensate for either an excess or a shortage
ofH+.
Cation Correct Answers A positively charged ion
Chemical Bonds Correct Answers An attraction
between two atoms resulting from a sharing of
outer-shell electrons or the presence of opposite
charges on the atoms. The bonded atoms gain
complete outer electron shells.
chemical equilibrium Correct Answers In a
chemical reaction, the state in which the rate of
the forward reaction equals the rate of the reverse
reaction, so that the relative concentrations of the
reactants and products do not change with time.
chemical reaction Correct Answers the process by
which one or more substances change to produce
