What are the seven properties that define
life?
What are the seven properties that define life?
TERM 2
Cell
DEFINITION 2
Lowest level of organization that can perform all activities
required for life.
TERM 3
Prokaryotic Cells
DEFINITION 3
SmallerLess complexlacks nucleuslacks membrane
TERM 4
Eukaryotic Cells
DEFINITION 4
LargerMore Complexhas nucleushas membrane
TERM 5
3 domains of life
DEFINITION 5
Bacteria, Archae, Eukarya
What type of organisms belong to bacteria?
Prokaryotes
TERM 7
What types of organisms belong to
archea?
DEFINITION 7
Bacteria; Prokaryotes
TERM 8
What types of organisms belong to Eukarya?
DEFINITION 8
Plants, Animals, fungi, protists: Eukaryotes
TERM 9
How does energy flow in an ecosystem?
DEFINITION 9
Producers convert energy from sunlight to chemical energy,
some are passed.
TERM 10
Theory VS. Hypothesis
DEFINITION 10
Theory - Broader in scope then a hypothesisHypothesis -
Educated guess for a set of observation and must be testable
Mass
number
number of protons and neutrons in the nucleus
TERM 17
Isotope
DEFINITION 17
Two atoms of an element that differ in number of neutrons
TERM 18
4 elements that make up 96% of human body
weight
DEFINITION 18
Carbon, Oxygen, Hydrogen, Nitrogen
TERM 19
Polar covalent Bonding
DEFINITION 19
One atom is more electronegative, and the atoms do not
share the electron equally
TERM 20
Non Polar Covalent Bonding
DEFINITION 20
the atoms share the electron equally
Does the chemical behavior of an atom
depend on the electron in the outermost shell
or the shell closest to the atomic nucleus?
Why or Why not? What is the outermost shell
called?
Because if it is filled up, the element is chemically stable and
will not bond.The outermost shell has the highest potential
energy, so electrons are more likely to be involved in bond
formation.valence shell
TERM 22
What is the chemical equilibrium in a cell?
DEFINITION 22
it is reached when the forward and reverse reaction rates are
equal.
TERM 23
If the valence shell is complete is the atom
reactive or non-reactive?
DEFINITION 23
Non-reactive because the shell is full
TERM 24
Potential energy Vs. kinetic energy What's the
difference?
DEFINITION 24
Potential: stored energy because of it's structure or
locationKinetic: energy of motionDifference: Kinetic is
continued in moving object, potential exists in stored form.
Kinetic is always doing work, potential is ready for release.
TERM 25
Ionic bonding and what causes it to happen?
DEFINITION 25
Ionic bonding: an attraction between an anion and
cationThrough ionic compound or salt
Heat Vs. Temperature
heat: total of all kinetic energy in a substanceTemperature:
average of all kinetic energy in a substance
TERM 32
Colloid
DEFINITION 32
a stable suspension of fine particles in a liquid
TERM 33
What property of water allows some insects
to "stand or walk" on water
DEFINITION 33
High surface tension
TERM 34
What does acid and bases do in solutions?
(think in terms of hydrogen ions)
DEFINITION 34
Acid: Hydrogen ion donors, they release H+Bases: Hydrogen
ion acceptors, they take up H+
TERM 35
how does a buffer minimize changes in the pH
of a solution?
DEFINITION 35
Because they are composed of an acid and base pair.
Why is ice able to float on water?
because hydrogen bonds in ice are more ordered, making ice
less dense. As a solid, (H2o) is less dense
TERM 37
Adhesion Vs. Cohesion Examples?
DEFINITION 37
A: the attraction of h2o to something other than itself.C: the
attraction of h2o to itselfEx: traveling against gravity in a
tree
TERM 38
Is water able to interact with non-
polar/hydrophobic substances? Why or why
not?
DEFINITION 38
No, water can't hydrogen bond with non polar substances b/c
they don't exhibit a charge
TERM 39
Study figure 3.10 (pH
scale)
DEFINITION 39
Acid- 0-6neutral - 7Basic - 8-14Understand how hydrogen
bonds play a part. Check study guide
