Answer:

D. Peptide bond

Explanation:

The reaction between one amino acid and another is

\rm H$_{2}$NCH(R)-CO-OH + H-NH-CH(R)COOH\\\\\longrightarrow \,\text{H${_2}$NCH(R)-} \underbrace{\text{CO-NH}}_{^\text{peptide}_{\text{bond}}}\text{-CH(R)COOH + H$_{2}$O}

The bond that joins the two amino acids is called a peptide bond.

A. is wrong. A 1,4-glycosidic bond is formed between two carbohydrate units.

B.  is wrong. An ester bond is the characteristic feature of fats.

C. is wrong. Hydrogen bonds are intermolecular attractive forces among molecules

<h3>What is Mike Velings talks about?</h3>

Industrial aquaculture has had a wide range of negative effects on the environment, including the overfishing of wild fish to feed carnivorous farmed fish and the escape of farmed fish from their containment, which endangers local wild fish populations.

Lastly, in the words of Mike Velings, We are approaching a worldwide food crisis, he said. At our current rate, we are already taking more fish from the ocean than it can naturally replace, despite the fact that almost 3 billion people rely on the ocean for their food. Mike Velings, an entrepreneur and conservationist, offers a solution in this fact-filled, eye-opening talk: the practice of farming fish. "We need to stop hunting the ocean and start farming it,"
