b.
Dehydration reactions occur in plants and hydrolysis happens in animals
c.
Dehydration reactions can occur only after hydrolysis
d.
Dehydration reactions act on polysaccharides, whereas hydrolysis happens in lipids
e.
Dehydration reactions assemble polymers and hydrolysis breaks them down

The classification of living things based on fossils is problematic because:
a.
fossils do not represent living organisms
b.
it only pertains to dinosaurs
c.
fossils are not available for some organisms
d.
DNA is only present in some organisms
e.

Amylose differs from glycogen due to the fact that:
a.
glycogen cannot be digested by most animals
b.
amylose is not branched
c.
only glycogen has beta-1-6 glycosidic bonds
d.
there are no alpha-glucose units in amylose
e.
glycogen is a straight polymer
b.
amylose is not branched
A new type of aquatic invertebrate is discovered that has light-detecting structures protruding from the top of its body that are globular and similar in shape to eyes found in fish, but they do not have eyelids or lenses. Most aquatic vertebrates, like fish, have two eyes inset on the sides of the head, and each eye has a membranous eyelid and lens. The common ancestor of the invertebrate and the fish did not have any eyes. The eye-like structures in the newly discovered invertebrate, when compared with the eyes of fish, are likely:
a.
analogous
b.
monogamous
c.
deciduous
d.
homologous
e.
a derivative of a finger
a.
analogous
a.

a.
without charge
b.
hydrophobic
c.
negatively charged
d.
positively charged
e.
nonpolar
d.
positively charged
a.
A methyl group.
b.
Any atom or group could be placed at this position.
c.
A hydrogen.
d.
A carboxyl group.
e.
This structure can not be an amino acid, regardless of what is placed at this position.
c.
A hydrogen.
a.
Estradiol has one carbonyl group, testosterone has two.
b.
Testosterone has two methyl groups, estradiol has only one.
c.
Estradiol is cis and testosterone is trans.
d.
Estradiol is a structural isomer of testosterone.
e.
Estradiol has fewer double bonds.
b.
Testosterone has two methyl groups, estradiol has only one.
a.
all of the bonds are covalent
b.
the molecular formula is C4H12
c.
the methyl groups are in cis
d.
the methyl groups can rotate around the C=C axis
a.
all of the bonds are covalent
a.
It is an amino acid with a long side chain
b.
It is a saturated fatty acid; a diet rich in this molecule may contribute to circulatory problems
c.
A diet rich in this molecule probably does not contribute to circulatory problems
d.
Molecules of this type are usually liquid at room temperature
e.
It is a triglyceride; a diet rich in this molecule may contribute to circulatory problems
b.
It is a saturated fatty acid; a diet rich in this molecule may contribute to circulatory problems
