Answer:
This is Law of Dominance.
Explanation:
- On crossing pure bred pea plants having one trait of a character with pure bred plants having a different trait of the same character , Mendel noticed that all the plants in the first filial generation were having only one trait though they received the factor for other trait.
- However, when he allowed these plants of first filial generation to pollinate themselves, the other trait also appeared in some plants of second filial generation.
- And thus the law of dominance was framed, which stated that, characters are controlled by discrete units called factors, these factors occur in pair and in a dissimilar pair of character one factor dominates and the other fails to appear.
Answer:
Answer is A. Two hydrogen atoms join together to form a molecule of hydrogen gas.

The electromagnetic attraction existing between hydrogen and other electronegative atom, such as nitrogen or oxygen, is known as hydrogen bond. It can also be explained as the electromagnetic attraction occurring when hydrogen binds to a higher or larger atom such as nitrogen.
Note that , the bond existing between two hydrogen atoms resulting in the formation of a molecule of hydrogen gas is covalent bond. Covalent bond can simply be explained as the sharing of electrons.
