When freshwater fish is placed in salt water, the water molecules contained in the fish’s body would pass through the cell membranes of the fish, causing the fish to lose water by diffusion. This sudden change in the molecular makeup of the fish would cause the fish to die.

Insulin is a hormone secreted by the pancreas that is important for metabolism and utilization of energy from the ingested nutrients - especially glucose. It keeps our blood sugar level from getting too high (hyperglycemia) or too low (hypoglycemia). The pancreas is a glandular organ in the digestive system and endocrine system of vertebrates.

Liver is the largest gland in human body. It is also the largest (internal) organ in our body and can weigh up to 1.5-1.6 kg for a human adult. The large size of the liver is matched by its functional complexity and involvement in a diverse array of regulatory mechanisms. It plays a major role in regulation of glycogen storage, decomposition of red blood cells, plasma protein synthesis, hormone production, and detoxification.

Aldehydes are organic chemical compounds that include a -carbonyl group (i.e. an oxygen atom attached to a carbon atom by a double covalent bond) and a hydrogen atom attached to the carbon atom of the carbonyl group: The presence of that hydrogen atom makes aldehydes very easy to oxidize. Or, put another way, they are strong reducing agents.

Correct Option: C

Diamond has a giant molecular structure. Each carbon atom is covalently bonded to four other carbon atoms. There are no free electrons or ions in diamond; so it does not conduct electricity. Except for most blue diamonds, which are semiconductors, diamonds are good electrical insulators.
