IB 150 Chapter 1 Questions With Complete Solutions
a theory serves as framework Correct Answers for developing a
new hypothesis
Activation energy Correct Answers Energy associated with the
breaking of covalent bonds, "helps get over the hump"
Activation energy Correct Answers The amount of kinetic
energy required to initiate a chemical reaction, specifically, the
energy required to reach the transition state
Active site Correct Answers The location in an enzyme
molecule where substrates bind and react
active site Correct Answers The part of an enzyme or antibody
where the chemical reaction occurs.
Active site Correct Answers The part of an enzyme that
provides a chemical environment conducive for forming
intermediate stages of a chemical reaction
Adaptation Correct Answers A hair double trade that increases
the fitness of an individual in a particular environment relative
to individuals lacking that trait
Adenine triphosphate or ATP Correct Answers A molecule
consisting of anatomy base, sugar, and three phosphate groups
that are linked together with covalent bonds that have high
potential energy. University used by cells is a monomer for
RNA synthesis into storage and transfer chemical energy
,After blood from arteries and arterioles passed through
capillaries Correct Answers veins carry it back to the heart
Air and water are dramatically different ventilatory media
because Correct Answers They have different densities,
viscosity's, and abilities to hold oxygen and carbon dioxide
all cells from cells hypothesis Correct Answers cells are
produced only when preexisting cells grow and divide
all organisms are made of Correct Answers cells
All the cells in a multicellular organism are connected by what
Correct Answers A common lineage
Alveoli Correct Answers any of the tiny, airfield sacks of a
mammalian ling
Animacules Correct Answers Means "little animals",
discovered by Anton van Leeuwenhoek known today as protists.
aorta Correct Answers The large arterial trunk that carries blood
from the heart to be distributed by branch arteries through the
body.
Aorta Correct Answers The major artery carrying oxygenated
blood away from the heart
,arteries Correct Answers carry blood away from heart;
oxygenated except for pulmonary circulation and umbilical
vessels of fetus
Arteries Correct Answers Tough thick walled vessels that take
blood away from the heart
arterioles Correct Answers small vessels that receive blood
from the arteries
Arterioles Correct Answers smallest arteries
atp Correct Answers (adenosine triphosphate) main energy
source that cells use for most of their work
atp Correct Answers Energy coupling agent
Atria are separated from ventricles by Correct Answers
atrioventricular valves
atrium Correct Answers Each of the two upper chambers of the
heart that receives blood that comes into the heart
because blood is under relatively low pressure by the time it
exits the tissues Correct Answers veins have thinner walls and
larger interior diameters arteries do
Blood flow in veins is speeded by Correct Answers skeletal
muscle activity in the extremities, which compresses large veins
, Boyles law Correct Answers If the volume occupied by a fixed
amount of gas increases, the gas pressure decreases. If that
volume declines, the gas pressure increases
capillaries Correct Answers Smallest blood vessels
Capillaries Correct Answers Vessels whose walls are just one
Celtic, allowing exchange of gases in other molecules between
blood and tissues
Capillary bess Correct Answers Network of capillaries
Carolus Linnaeus Correct Answers (1707-1778) Founder of
taxonomy, the branch of biology concerned with naming and
classifying organisms. Developed two part system of naming
organisms.
Catalyst Correct Answers Any substance that increases the rate
of a chemical reaction without its self undergoing any
permanent chemical change
catalyst Correct Answers substance that speeds up the rate of a
chemical reaction
Catalyst Correct Answers substance that speeds up the rate of a
chemical reaction
cell theory Correct Answers All organisms are made of cells,
and all cells come from pre-existing cells
