A 0.01 M solution of a substance has a pH of 2. What can you
conclude about this substance? Correct Answers It is a strong
acid that ionizes completely in water.
,A carbon atom is most likely to form what kind of bond(s) with
other atoms? Correct Answers covalent
A carbon skeleton is covalently bonded to both an amino group
and a carboxyl group. When placed in water it Correct Answers
would function as both an acid and a base.
A cell has the following molecules and structures: enzymes,
DNA, ribosomes, plasma membrane, and mitochondria. It could
be a cell from Correct Answers nearly any eukaryotic
organism
A cell with a predominance of free ribosomes is most likely
Correct Answers producing primarily cytoplasmic proteins.
A certain kind of snail can have a right-handed direction of shell
coiling (D) or left-handed coiling (d). If direction of coiling is
due to a protein deposited by the mother in the egg cytoplasm,
then a Dd egg-producing snail and a dd sperm-producing snail
will have offspring of which genotype(s) and phenotype(s)?
Correct Answers 1/2 Dd:1/2 dd; all right coiling
A chemical reaction that has a positive ΔG is correctly described
as Correct Answers endergonic.
A chemist wishes to make an organic molecule less acidic.
Which of the following functional groups should be added to the
molecule in order to do so? Correct Answers amino
A compound contains hydroxyl groups as its predominant
functional group. Which of the following statements is true
,concerning this compound? Correct Answers It should
dissolve in water.
A covalent bond is likely to be polar when Correct Answers
one of the atoms sharing electrons is much more electronegative
than the other atom.
A covalent chemical bond is one in which Correct Answers
outer-shell electrons of two atoms are shared so as to
satisfactorily fill the outer electron shells of both atoms.
A dietary Calorie equals 1 kilocalorie. Which of the following
statements correctly defines 1 kilocalorie? Correct Answers
1,000 calories, or the amount of heat required to raise the
temperature of 1 kg of water by 1°C
A frameshift mutation could result from Correct Answers
either an insertion or a deletion of a base
A gene is considered to be non-Mendelian in its inheritance
pattern if it seems to "violate" Mendel's laws. Which of the
following would be considered Mendelian? Correct Answers a
gene transmitted to males from the maternal line and from
fathers to daughters
A given solution contains 0.0001(10-4) moles of hydrogen ions
[H+] per liter. Which of the following best describes this
solution? Correct Answers acidic: will give H+ to weak acids,
but accept H+ from strong acids
, A group of cells is assayed for DNA content immediately
following mitosis and is found to have an average of 8
picograms of DNA per nucleus. How many picograms would be
found at the end of S and the end of G2? Correct Answers 16;
16
A man who is an achondroplastic dwarf with normal vision
marries a color-blind woman of normal height. The man's father
was 6 feet tall, and both the woman's parents were of average
height. Achondroplastic dwarfism is autosomal dominant, and
red-green color blindness is X-linked recessive.
How many of their daughters might be expected to be color-
blind dwarfs? Correct Answers none
A molecule that is phosphorylated Correct Answers has an
increased chemical potential energy; it is primed to do cellular
work.
A molecule with the chemical formula C6H12O6 is probably a
Correct Answers carbohydrate and monosaccharide only.
A molecule with the formula C18H36O2 is probably a Correct
Answers fatty acid.
A mycoplasma is an organism with a diameter between 0.1 and
1.0 µm. What does the organism's size tell you about how it
might be classified? Correct Answers It could be a very small
bacterium.
