a) ANA, hydrogen.
b) adenine base, covalent.
c) phosphate groups, covalent.
d) ribose sugar, ionic.
e) adenosine group, Van der Waals.
25) what information vould a phylogenetic tree gives us?
a) the common ancestor of two seemingly unrelated organisms.
b) the molecular relationship between two organisms.
c) all of this information could be obtained by a phylogenetic tree.
d) the anatomical relationship between two organisms,
e) the point in evolutionary history at which two organisms diverged.
3) which of the following could have the easiest time crossing the plasma membrane without help from the transport protein?
a) a highly polar amino acid.
b) a charged amino acid.
c) an ion.
d) a large, globular protein.
e) a small nonpolar amino acid.
Explanation / Answer
(1)
ATP stores energy in its phosphate group. Hydrolysis of ATP release energy by breaking Covalent bonds.
(2)
Phylogenetic tree gives information about the point in evolutionary history at which two organisms diverged.
Phylogenetic tree is also called evolutionary tree.
(3)
a small nonpolar amino acid is the molecule that can easily cross the plasma menbran without help of transport
protein.
Because nonpolar molecules are hydrophobic. so, dissolve in the lipid bilayer of the membrane and cross it easily,
without help of transport proteins.
