The correct answer is B The young sun's solar winds pushed gases outward to the outer solar system.
The atomic mass or mass number of an atom is written as superscripts attached to the symbol of that element.
<h3>Atomic mass or mass number</h3>
- The atomic mass or mass number of an atom of an element is the sum of the number of protons and neutrons in the nucleus of the atom.
The atomic mass or mass number of an atom is usually written as superscripts attached to the symbol of that element.
For example, given an element X, the atomic mass or mass number can be shown as follows:
where a = atomic number
b = atomic mass/mass number
Therefore, the atomic mass or mass number of an atom is written as superscripts attached to the symbol of that element.

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.
