Answer:
Electromagnetic waves can travel through a vacuum, that is an empty space, whereas mechanical waves cannot. They need a medium to travel such as water or air. Ripples in a pond are an example of mechanical waves whereas electromagnetic waves include light and radio signals, which can travel through the vacuum of space.
Explanation:
They all contain carbonyl groups. DNA has carbonyl groups in it's nucleotide ring structures. Every amino acid in a protein has a carbonyl group in its backbone structure. Fats too have carbonyl groups in their structures attached to hydrocarbon chains
Beneath the dermis, and is mainly used for fat storage

Choice C. Sodium bicarbonate acted as a pH buffer in Solution 2.
Explanation:
Sodium carbonate is used as pH buffering agent. Buffering agent is a type of solution which contains weak base or acid which stabilize the solution when another strong acid or base is added to the solution. If acid is added, the weak base that is present in the solution reacts with it and when base is added, weak acid reacts with it.
8 miles per hour. (Divide the 16 miles by the 2 hours traveled)
