Thiamin deficiency - Beri-beri, polyneuritis, and Wernicke-Korsakoff syndrome.

Riboflavin deficiecy - cheilosis, angular stomatitis, and dermatitis.

Niacin deficiency - Pellagra (with diarrhea, dermatitis, and dementia)

Explanation:

Thiamin, riboflavin, and niacin belong to a group of vitamins known as the B-complex vitamins. The three substances are known to function as co-enzyme in different processes within the body and hence, their deificiency has several implications.

Thiamin deficiency is known to cause Beri-beri, polyneuritis, and Wernicke-Korsakoff syndrome.

Riboflavin deficiecy is known to cause cheilosis, angular stomatitis, and dermatitis.

Niacin deficiency is known to cause Pellagra with diarrhoea, dermatitis, and dementia

Which kind of of electrical charge is found on a hydrogen atom of a polar water molecule? A. A negative charge, because of a cov

charle [14.2K]

Answer:

D. A positive charge, because of a covalent bond with oxygen

Explanation:

A water molecule contain both hydrogen and oxygen atom. Water is a polar molecule because it has positive electric charge in one of it's poles and negative charge on the other. The hydrogen is positively charged and the oxygen is negatively charged which are bonded by covalent bond. Hydrogen is positively charged because it cannot attract electrons strongly like oxygen which is positively charged. There is unequal sharing of electrons in water molecules and this is why oxygen is slightly negative and hydrogen is slightly positive.
