Answer:
Explanation:
A peptide bond is a chemical bond formed between two molecules when the carboxyl group of one molecule reacts with the amino group of the other molecule, releasing a molecule of water (H2O). ... Polypeptides and proteins are chains of amino acids held together by peptide bonds, as is the backbone of PNA.
The answer is B: <span>electricity is required to produce the hydrogen fuel. This could still be polluting because much electricity is produced using fossil fuels. However, this question is a bit misleading. If electricity used to manufacture hydrogen is sourced from renewable energy, such as hydropower, solar or wind energy, then hydrogen power in turn is also not polluting.</span>
Answer:Carbon dioxide accounts for most of the nation's emissions and most of the increase since 1990. Transportation is the largest source of greenhouse gas emissions in the United States, followed by electricity generation.
Explanation:
The answer would be : use less water while farming
reason: leaching happens when excess water takes water soluble nutrients out of the soil, so less water would stop leaching from occuring.
Answer: oxygen and sugar molecules
Explanation: During cellular respiration, cells produce energy through the breakdown of sugar molecules in the presence of oxygen. Cellular respiration is a process by which glucose is broken down in the presence of oxygen to produce energy, carbon dioxide and water. The energy produced in cellular respiration is used to drive other cellular processes.
The equation for cellular respiration is C6H12O6 + 6O2 --> 6CO2 + 6H2O + Energy.
