A hypothesis cannot be wrong, because it is an educated guess. You cannot prove a guess wrong. A guess is something you think, and there is no right or wrong answer to thoughts.
The correct answer is secondary structure of proteins is formed by the hydrogen bonding between amino acid chains.
Explanation:
The secondary structure of protein is generally stabilized by peptides bond along with hydrogen bonding between hydrogen atom and an electronegative atom such as oxygen.
The secondary structure both alpha helix and beta pleated sheet are stabilized by hydrogen bonding beside the presence of peptide bonds.

Answer:
A few basic principles go a long way toward explaining how and why air moves: Warm air rising creates a low pressure zone at the ground. Air from the surrounding area is sucked into the space left by the rising air. Air flows horizontally at top of the troposphere; horizontal flow is called advection. The air cools until it descends. Where it reaches the ground, it creates a high pressure zone. Air flowing from areas of high pressure to low pressure creates winds. Warm air can hold more moisture than cold air. Air moving at the bases of the three major convection cells in each hemisphere north and south of the equator creates the global wind belts.
Explanation:
Blood enters the heart through two large veins, the inferior and superior vena cava, emptying oxygen-poorblood from the body into the right atrium of the heart.i As the ventricle contracts, blood leaves the heartthrough the pulmonic valve, into the pulmonary artery and to the lungs where it is oxygenated
How does blood flow through the heart step by step?
Blood from the body flows:
1. to the superior and inferior vena cava,
2. then to the right atrium.
3. through the tricuspid valve.
4. to the right ventricle.
5. through the pulmonic valve.
6. to the pulmonary artery.
7. to the lungs
