Option A, A hydrogen bond is a polar covalent bond between hydrogen and another atom.
Explanation:
Hydrogen bond is formed between a hydrogen atom and any other electronegative atom such as Nitrogen, fluorine, iodine, chlorine, oxygen etc.
Hydrogen bonds are weak bonds that are formed due to the attraction between the two opposite poles i.e positive and negative poles. These are weak inter-molecular forces that can be easily broken off.
A fault is found that cuts through lower rock layers but not those above it. What can most likely be concluded? The fault is the same age as the layers it cuts through, and the same age as the layers above it.
A recessive trait inheritance could be more prevalent in a population than the dominant because mutation could occur because the mating does not have a wide variation causing a lethal gene or an autosomal sex link to be easily passed on the offspring
