scientific point of view example:
testing the effect of antibiotics on e coli can help prevent deaths ....
basic or pure science =
discovering knowledge for knowledge sake
domain eukaryotic include all of the following except
Archaea bacteria
main purpose of any single experiment is to
test a prediction that is based on a hypothesis that will then have to be repeated
which of the following is not a fundamental character of life
ability to communicate w other members of the same life form
the advantage of controlled experiments is that
all variables are held constant except for one
all reptiles have dry scales: a snake has dry scales, therefore a snake is a reptile is an example of
deductive reasoning
The group matching all the conditions of the experimental group except the variable being tested is called the _______ group
control
What is a heterotroph?
an organism that obtains energy and organic molecules from other organisms
which of the following is common to all living things
metabolism
Ice is used in beverages primarily because
it absorbs a lot of heat when it melts
nitrogen- 14 and nitrogen Dash 15 or isotopes. Nitrogen Dash 415 is used to determine protein structure. Which of the following is true
nitrogen 15 has more neutrons than nitrogen 14
The hydrogen bond between two water molecules arises because water is
polar
2 atoms are held together in covalent bonds because of forces between the
electrons
The mass number of atoms is determined primarily by the
sum of the number of protons and neutrons it contains
which component of an atom does not significantly add to its mass
electron
if you place a tube in a dish of water the water will move up the two by capillary action because water
can form hydrogen bonds and r sticky to each other
Sweating is a useful cooling device for humans because water
takes up a great deal of heat in changing from its liquid state to its gaseous state.
The part of the atom that determines how the atom behaves in a chemical reaction is the
electron
The difference between an acid and a base is that an acid ____ , where as a base ___
releases H +ions in a solution, accept H + ions
which of the following atoms usually has the greatest number of covalent bonds with other atoms
carbon
lactose or milk sugar which is composed of one glucose unit and one galactose unit can be classified as
disaccharide
which of the following is responsible for making every amino acid unique
R group
ionic bonds form between
oppositely charged ions
Carbonic acid and sodium bicarbonate act as a buffer is in the blood. When a small amount of acid is added to this blood, the H plus ions are used up as they combine with the bicarbonate ions. When this happens the ph of the blood
doesn't change
Which property of water allows organisms to live in water even in cold areas of earth
high specific heat
which four elements make up 93.3% of human body weight
carbon oxygen nitrogen and hydrogen
Which particles are found in the nucleus of an atom?
protons and neutrons
A molecule that has an important role in long-term storage of energy in animals is
glycogen
lipids are
all of the above
The main function of cellulose, the most abundant organic compound on earth is
to provide mechanical strength to plant cell walls
which of the following statements about proteins is true
some function as enzymes
in DNA a pairs with T and C with G; these are an example of a specific type of reaction called
complementary base pairing
you have isolated an unidentified liquid from a sample of beans. You add a liquid to a beaker of water and shake vigorously. After a few minutes, the water and the other liquid separate into two layers to which class of large biological molecules does this unknown liquid most likely belong
lipids
carbs proteins and nucleic acids
are broken down in Hydrolysis reactions
A molecule that has an important role in limiting what gets into an out of cells is
phospholipid
Leucine and Valine do not interact with water therefore they are
Nonpolar and hydrophobic
A protein can best be defined as a polymer
of amino acids
oxygen has an atomic mass of 16 and an atomic number of eight how many neutrons are present
eight
which of the following is the correct order of biological hierarchy
cellular, organismal, populational, ecosystem, biosphere
A fat contains fatty acids and
glycerol
which of the following is not a difference between DNA and RNA
dna is a monomer where as RNA is a polymer
A type of protein that functions by helping other proteins fold correctly is called a
chaperone protein
in a biological membrane, the phospholipids are arranged with a fatty acid chains facing the interior of the membrane. As a result the interior of the membrane is
hydrophobic
DNA carries genetic information in its
sequence of nucleotide bases
The scientific method is used to
answer specific questions about the natural world
The monomers for ______ are ______
carbohydrates, monosaccharides
when Atimd gain or lose electrons, they become negatively or positively charged. These negatively or positively charged particles are known as
ions
negatively charged subatomic particles that have almost no mass are called
electrons
which forms the outer exoskeleton of insects and is found in cell walls of many fungi
chitin
Because oxygen is more electronegative than hydrogen, the water molecule is
valences
