____________ is best described as away of knowing.
Science
A well-tested explanation that explains a lot of observations
is a
theory
A personal preference or point of view is a
bias
The process by which organisms keep everything inside their bodies within
certain limits is called
homeostasis.
The branch of biology dealing with interactions among organisms and between
organisms and their environment is called
ecology
The simplest grouping of more than one kind of organism in
the biosphere is a
community
The lowest level of environmental complexity that includes living and nonliving
factors is the
ecosystem
Give an example of a primary producers
plants
__________ get their energy by consuming only plants.
herbivores
__________ get their energy by consuming only other
animals.
carnivores
What animals eat both producers and consumers?
omnivores
A word that means the same thing as consumer is
heterotroph
The repeated movement of water between Earth’s surface and the atmosphere is called
the water cycle
Nonliving factors in the environment
abiotic
Living factors within an ecosystem
biotic
Which are two ways a population can increase in
size?
increased in birthrate and immigration
Something that controls the growth or size of a population
is a
limiting factor
Competition, predator/prey relationships, parasitism, crowding, and disease are
examples of density-____________ limiting factors
dependent
Which are two ways a population can decrease in
size?
decreased birthrate and emigration
The gray-brown haze often found over large cities is called
smog
Who used a compound microscope to see chambers within cork and named them
“cells”?
Robert Hooke
What advance in technology made the discovery of cells
possible?
the microscope
Cells are the basic units of life.All living things are made of cells.
All cells are produced from existing cells.
The following are principle of the__________
cell theory
Looking at a cell under a microscope, you note that the
cell lacks a nucleus. What kind of cell is it?
prokaryote.
Give an example of a prokaryotes?
bacteria
Which organelle converts the chemical energy stored in food into compounds that are more convenient for the cell to use?
mitochondrion
Storing DNA is a function of the
nucleus
Which organelle would you expect to find in plant cells but
not animal cells?
chloroplast
Which of the following structures serves as the cell’s
boundary from its environment?
cell membrane
Which means of particle transport requires input of
energy from the cell?
active transport
An ______________is a group of organs that work together to
perform a specific function.
organ system
A group of similar cells that perform a particular function is
called
a tissue.
__________ is released from ATP when a phosphate group
is removed.
Energy
Organisms that cannot make their own food and must obtain energy from external sources
are called
heterotrophs
Autotrophs produce carbohydrates during
photosynthesis
In the overall equation for photosynthesis, six molecules
of carbon dioxide and six molecules of water result in a
molecule of sugar and six molecules of
oxygen.
The products of the light-dependent reactions are ATP, NADPH, and __________.
oxygen gas
Another name for thelight-independent reactions is
Calvin cycle
The Calvin cycle takes place in the
stroma
What is a product of the Calvin cycle?
high-energy sugars
What is the correct sequence of events in cellular respiration?
glycolysis Krebs cycle electron transport
What are the reactants in the equation for cellular
respiration?
glucose and oxygen
What is the products of cellular respiration?
Water, Carbon dioxide, and ATP
Cellular respiration is called an aerobic process because it
requires
oxygen
Where does glycolysis takes place in the cell?
cytoplasm
Glycolysis requires how many ATP to get the reaction started?
2 ATP
What are the electron carriers that plays a role in cellular
respiration?
NAD+ and FAD+
Cellular respiration uses 1 molecule of glucose to produce
approximately ___ ATP molecules.
36
The two main types of fermentation are called
alcoholic and lactic acid
What high-energy electron carriers pass H+ ions onto the
electron transport chain?
NADH and FADH2
