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
