Answer:
Microtubules
Explanation:
Microtubules can potentially form a physical link between the plasma membrane.
Answer:
The options are
A. secondary structure ... hydrogen bonds
B. secondary structure ... peptide bonds
C. tertiary structure ... hydrogen bonds
D. primary structure ... covalent bonds
E. tertiary structure ... covalent bonds
THE CORRECT ANSWER IS A.
A. secondary structure ... hydrogen bonds
Explanation:
The secondary structure of a polypeptide shows the localized regions of its organised structure being upheld by hydrogen bonds among the major groups
-NH and C = O
At the same time, it inhibits the hydrogen bonds of the side chains from influencing the reaction process.
The polypeptide secondary structure shows the dexterity to curl or fold as sustained by the polypeptide chains.
Since Lithium has one valence electron that means it needs to lose it to form a stable structure. That means it's valence is equal to one. Oxygen has six atoms, in order to form a stable octet structure it needs to accept 2 electrons, therefore it's valence is 2.
Therefore two Lithium atoms bond with one oxygen atom to form Li2O
