Question

Which of the following can be obtained from fishes?
A. Proteins and vitamin D
B. Wool
C. Oil
D. Both A and C

Answer 1

Hint: Several types of proteins, oils, and vitamin D are obtained from the fishes. Fish oil, liver oil, vitamin D, and protein obtained from an excellent source of nutrients from fish.

Complete answer:
-Fish is a rich source of omega-3 fatty acids and several amino acids.
-The unsaturated fats (containing double and triple bonds, hence they can be hydrogenated in the body to form saturated forms of fatty acids/ fats) present in fish are known as omega-3 fatty acids. Omega-3 fatty acids and other nutrients in fish may benefit heart health and reduce the risk of dying of heart disease.
-Seafood contains high-quality protein that includes all of the essential amino acids (amino acids that can’t be synthesized by the human body and have to be derived from foods) for human health, making it a complete protein source. Tuna, salmon, tilapia, and cod are some fish that are taken worldwide solely for their protein content. Two of the most important and nutritious omega-3 fatty acids contained in fish oil are eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA)
Therefore, Option D: Both A and C

Note:
Docosahexaenoic acid (DHA) is an omega-3 fatty acid that is the primary structural component of the human brain, cerebral cortex, skin, and retina. It can be synthesized from alpha-linolenic acid or obtained directly from maternal milk, fish oil, or algae oil. It is highly essential for the development of the brain in the fetus.
Cod liver oil is a dietary supplement (used for reducing inflammation and lowering the blood
pressure. It also contains vitamins A and D which provides many other health benefits) derived from the liver of cod fish. As with most fish oils, it contains the omega-3 fatty acids
eicosapentaenoic acid and docosahexaenoic acid.
