Name two prokaryote
domains
domain Archae and domain
Eubacteria
What is the lowest level of
biological organization that
can perform all the activities
required for life?
the cell
Name two properties or
processes associated with
living things.
Evolutionary adaptations
energy processing
responding to environment
growth and reproduction
List the hierarchy of
biological organization from
the least to the most
complex level.
Molecule, cell, tissue, organ,
organ system, organism,
population, community,
ecosystem, biosphere
According to Charles Darwin,
how do organisms become
adapted to their
environment?
When they possess
inheritable traits that
enhance their survival and
reproductive success.
How do isotopes of the
same element differ from
each other?
The number of neutrons
What does the reactivity
of an atom depend on?
The number of valence
electrons (more specifically,
the unpaired valance
electrons)
What results from an
unequal sharing of electrons
between atoms?
a polar covalent bond
What is the difference
between ionic and covalent
bonds?
Covalent bonds result when
electrons are shared and
ionic bonds involve the
electrical attraction
between atoms as a result of
the transfer of electrons.
Why are hydrocarbons not
soluble in water?
The majority of their bonds
are nonpolar covalent
carbon-hydrogen linkages
What are some
characteristics of
hydrophobic substances?
They repel water
because they contain
nonpolar covalent bonds
Why does ice float in water?
Hydrogen bonds stabilize
and keep the molecules of
ice farther apart than the
water molecules of liquid
water.
Why is water able to form
hydrogen bonds?
Because water is a polar
molecule
What would be the pH of a
solution with a hydroxide ion
concentration of 10-12 M?
pH 2
How does a buffer help
resist shifts in pH?
It can donate hydrogen ions
to a solution when they have
been deplete and it can
accept hydrogen ions when
they are in excess.
Polymers of polysaccharides,
fats and proteins are all
synthesized from monomers
by which process?
Dehydration synthesis
Lactose is composed of one
glucose molecule joined y a
glycosidic linkage to one
galactose molecule. How is
lactose classified?
A disaccharide
Name two functional groups
found in amino acids.
Carboxyl and amino
Why do the 20 different
amino acids exhibit
different physical and
chemical properties?
Because they have different
side chains (R groups)
Describe the composition of
a nucleotide
A 5-carbon sugar, a
phosphate group, and a
nitrogenous base
The quicker picker upper
Bounty paper towels
They’re “magically” delicious
Lucky Charms cereal
Betcha can’t eat just one
