A _____ f is a set of ordered pairs that
pairs each element x of one set, called
the domain (input) of the function, with
a unique element f(x) of another set,
called the range (output) of the
function. - correct answer=✔✔function
1
,A circle with radius r has
circumference, C, given by - correct
answer=✔✔C = 2πr
and an area, A, given by - correct
answer=✔✔A = πr²
The diameter of circle, d, is twice the
radius. That is, - correct answer=✔✔d =
2r
Homeostasis. - correct answer=✔✔All
living organisms exhibit homeostasis,
or the ability to maintain a state of
internal balance. For example, if the
environmental temperature increases,
the human body begins to perspire,
and the cooling effect of evaporation
2
,decreases the surface temperature of
the skin. Likewise, a disruption in any
system will set off a diverse set of
control mechanisms that return the
organism to a state of internal
balance.
Every living thing needs energy that
they produce or acquire in order to
exist, grow, and reproduce. Some
organisms (called autotrophic
organisms) are capable of harnessing
energy from sunlight and using it to
produce glucose, the main source of
energy for the organism. Others
(called heterotrophic organisms)
capture energy by eating plants or
other animals. - correct
answer=✔✔Energy.

, autotrophic organisms) - correct
answer=✔✔are capable of harnessing
energy from sunlight and using it to
produce glucose, the main source of
energy for the organism.
heterotrophic organisms) - correct
answer=✔✔capture energy by eating
plants or other animals.
Animal and plant cells contain smaller
structures, called _____, which are
specialized to fulfill specific functions
within the cell. Mitochondria, for
example, break down glucose to
provide energy to the cell. Bacterial
cells lack most of these organelles. -
correct answer=✔✔organelles
