atoms of the same element with a different atomic mass

Which best describes a "T" Theory?

Broader in scope and allows predictions

The secondary structure of a protein is

formed by hydrogen bonding only

One dehydration reaction can

bring together 2 monomers to make a polymer

responsible for water's high surface tension

nonpolar covalent bonds

are when electrons are shared evenly between atoms

result in molecules that have charged areas

An independent variable is

the factor that is deliberately manipulated

A null hypothesis is defined as a hypothesis that says

there is no statistical significance between 2 variables

How are you going to do on the test tomorrow?

great!, fabulous!, awesome!, I will do my very best.

A dependent variable is

the factor that changes as a result of manipulation

Standard deviation is

the amount of "spread" of a group of data

Answers

1
A nucleotide does NOT contain which of the following
sugar
nitrogenous base
phosphate
amine
2
steroids are
always bad
considered proteins
considered lipids
considered carbohydrates
3
Isotopes are
Caused by a change in the number of electrons
atoms of the same element with a different atomic mass
caused by a change in the number of protons
not useful in biology
4
Nothing in biology makes sense except in the light of
DNA
nature
evolution
cells
5
What are the main 4 macroelements?
C H O P
C O N Mg
C H O N
C H K Na
6
Heat of vaporization
is hydrophilic
moderates earth's climate
is due to the covalent bonds in H2O
explains why frozen water is less dense than liquid water
7
saturated fatty acids
are liquid at room temperature
cause kinks in the molecules shape
have at least one double bond
have no double bonds
8
Which best describes a "T" Theory?
Broader in scope, but does not allow predictions
Supported by most evidence
Broader in scope and allows predictions
A prediction, but is not universally agreed upon
9
this is an example of which type of bond
covalent bond
disulfide bridge
hydrogen bond
ionic bond
10
The secondary structure of a protein is
formed by hydrogen, covalent, ionic, and hydrophobic
formed by hydrogen bonding only
the order of amino acids
formed by hydrogen and covalent bonding
11
Are you worried about the test tomorrow?
nope!
yes!
12
One dehydration reaction can
break a polymer into 2 monomers
break multiple polymers into monomers
bring together multiple monomers to make a polymer
bring together 2 monomers to make a polymer
13
Which sugar would be incorporated into a DNA molecule and which would be in an RNA molecule?
pink is DNA, blue is RNA
pink is RNA, blue is DNA
both are DNA
both are RNA
14
lipids are
contain 3 fatty acids
always liquid at room temperature
always amphipathic
insoluable in water
15
cohesion is
the amount of heat required to change temp by 1C
the ability of water to cling to other surfaces
responsible for water's high surface tension
silly
16
T or F. The scientific method must move in a straight "line"
False
True
17
nonpolar covalent bonds
are when electrons are shared evenly between atoms
when electrons are shared unevenly between atoms
are a relatively weak bond compared to others
are the same as ionic bonds
18
adenine pairs with which nitrogenous base in DNA
thymine
cytosine
guanine
uracil
19
A hypothesis must be
an "if.... then..." statement
explain why
all of the above!
testable
20
polar covalent bonds
result in neutral molecules
result in H-bonding
are when electrons are shared evenly between atoms
result in molecules that have charged areas
21
plants synthesize
glycogen and chitin
cellulose and glycogen
starch and glycogen
cellulose and starch
22
Which is NOT a property of living things?
grows/ develops
order
individuals can evolve
reproduces
23
The independent variable in the following experiment would be...
type of light
plant height
type of plant
red plant
24
this is an example of what type of bond
phosphodiester linkage
polar covalent bond
dehydration synthesis
hydrogen bond
25
which is not a functional group of an amino acid?
H
R group
COO-
CH2 - CH3
26
An independent variable is
the factor that is deliberately manipulated
a group that serves as a standard of comparison
the factor that changes as a result of manipulation
the factor that never changes
27
The pentose sugar in RNA is a
ribose always
deoxyribose always
neither
either deoxyribose or ribose
28
Cells build carbohydrate polymers by using energy to form
peptide linkages
glycosidic linkages
hydrogen linkages
phosphodiester linkages
29
Which is NOT an example of a monosaccharide?
glucose
fructose
galactose
cellulose
30
Hydrogen bonds
weak but don't break often
weak and constantly breaking
are very strong by themselves
very rarely break
31
T or F. Microelements (aka trace elements) are not needed for an organism to live.
True
False
32
A null hypothesis is defined as a hypothesis that says
there is statistical significance between 2 variables
there are many explanations of what is happening
there is no explanation of what is happening
there is no statistical significance between 2 variables
33
How are you going to do on the test tomorrow?
great!
fabulous!
awesome!
I will do my very best.
34
A good experiment does NOT require which of the following
replication
a control group for each independent variable
randomization
confounding variables
35
A dependent variable is
the factor that changes as a result of manipulation
the factor that is deliberately manipulated
a prediction of what will happen in an experiment
group that serves as a standard of comparison
36
the monomer of a protein is
a Carbon atom
a nucleotide
a peptide bond
an amino acid
37
Standard deviation is
the amount of "spread" of a group of data
the same as the average
the measure of the distance of one data point to the average
too confusing to understand
