Answer:
1)El ciclo del agua no se inicia en un lugar específico, pero para esta explicación asumimos que comienza en los océanos. ... Corrientes ascendentes de aire llevan el vapor a las capas superiores de la atmósfera, donde la menor temperatura causa que el vapor de agua se condense y forme las nubes.
2)El sol, que dirige el ciclo del agua, calienta el agua de los océanos, la cual se evapora hacia el aire como vapor de agua. Corrientes ascendentes de aire llevan el vapor a las capas superiores de la atmósfera, donde la menor temperatura causa que el vapor de agua se condense y forme las nubes.

Answer: Peptide bond
Explanation:
An amino acid is an organic molecule with an amino group (-NH2) and a carboxyl group (-COOH). Amino acids are part of proteins and they play a key role in almost all biological processes.
Two amino acids combine in a condensation reaction between the amino group of one and the carboxyl of the other, releasing a water molecule and forming an amide bond called a peptide bond. These two amino acid "residues" form a di-peptide, if a third amino acid is attached a tripeptide is formed and so on, successively, until a polypeptide is formed. This reaction takes place naturally inside the cells, in the ribosomes. So, <u>peptides and proteins are formed by the binding of amino acids by peptide bonds.</u>
The genetic code codes the twenty different amino acids, also called residues, which constitute the links that make up peptides, which when they form polypeptide chains and reach molecular weights are called proteins. So the peptide bond is a link between the amino group (-NH2) of one amino acid and the carboxyl group (-COOH) of another amino acid.
