According to the video which type of biomolecule would want to have if you were swimming across the English Channel?

A. Nucleic Acids

B. Proteins

C. Carbonhydrates

D. Lipids

The answer is C

Explanation:

Therefore, in order to swim in the English channel, in which its waters are extremely cold, we need  carbohydrates like glucose that provide 4 kilocalories per gram. ... Fats are much more energetic foods, producing about 9 kilocalories of energy per gram, more than double that of sugar. Experts recommend that no more than 30% of the calories in our diet come from fat.

The best answer is "B"

Proteins.

Explanation:

Protein repairs and rebuilds the muscles after the stresses of training in addition to warding off soreness.

the transfer of energy between two molecules spaced just nanometers apart plays a key role in many technologies, including photovoltaics, quantum information systems, lighting, and sensors, as well as in biophysics to measure nanometer distances and in photosynthesis. but an open question in this area is what effect, if any, the surrounding photonic environment has on this nanoscale energy transfer. by designing and performing a carefully controlled experiment to answer this question, scientists have settled the debate and found clues to improving the efficiency of many of the technologies that rely on this process.

explanation:

sulfur dioxide

explanation: acid rain is caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the air. these substances can rise very high into the atmosphere, where they mix and react with water, oxygen, and other chemicals to form more acidic pollutants, known as acid rain.
