Question

question 6 (1 point) saved proteins produced by the immune system in response to a foreign protein or virus are called: deoxyribonucleic acid (dna) enzymes antibodies hormones question 7 (1 point) saved the secondary structure of proteins refers to the combination of polypeptide chains. sequence of amino acids in the chain. strong bonds between loops of the chain. straight, folded, or coiled shape of the amino acid chain. question 8 (1 point) saved the amount of protein that most americans eat is less than we need. more than we need. about the amount we need. very different from day to day.

Explanation:

For Question 6: Antibodies are proteins made by the immune system to fight foreign substances like proteins or viruses. DNA is genetic material, enzymes are biological catalysts, and hormones are signaling molecules.
For Question 7: The secondary structure of proteins is about the local folding patterns like alpha - helices or beta - sheets which result in straight, folded, or coiled shapes of the amino - acid chain. The combination of polypeptide chains is quaternary structure, the sequence of amino acids is primary structure, and strong bonds between loops are not the definition of secondary structure.
For Question 8: In general, most Americans consume more protein than their body actually needs due to diets high in animal products.

Answer:

Question 6: C. Antibodies
Question 7: D. straight, folded, or coiled shape of the amino acid chain
Question 8: B. more than we need
