Explanation:
The wastewater produced by humans like from the human toilets is dumped into the flowing river bodies mostly in rivers and in the lakes also.
The human wastewater is rich in the nutrient contents like the phosphorus, nitrogen, and potassium. These nutrients could be accumulated in the lakes which could cause eutrophication in the lakes and rivers.

Explanation: Type I diabetes mellitus is a type of diabetes in which the pancreas produces little or no insulin. Type I diabetes is an autoimmune condition in which the body's immune system fights and destroys the beta pancreatic cells that produces insulin, thereby leading to the production of too little or no insulin at all.
Type I diabetes is called juvenile diabetes or insulin dependent diabetes mellitus. Insulin is a hormone produced by the beta cells of the pancreas that regulates the blood glucose concentration. Insulin is released by the beta cells of the pancreas in response to high blood glucose level after a meal where insulin stimulates the uptake of glucose by muscle tissues and activates glycogen synthase an enzyme that catalyzes glycogenesis (synthesis of glycogen from glucose). The actions of insulin results in a fall in the blood glucose concentration.
