introduction: An enzyme called urease attacks the nitrogen and carbon link in amide compounds like urea and produces the alkaline end product ammonia as a result. Antibodies; immune system creates protective proteins called antibodies. They bind to foreign substances known as antigens, including bacteria, fungi, viruses, and poisons, and expel them from our bodies.answer: 1)Ammonia and CO2 are produced when urea is hydrolyzed. The solution becomes more alkaline due to the creation of ammonia, and the pH change is indicated by phenol red, which turns from pale orange to magenta (pink). Within 24 hours, rapid urease-positive microbes turn the entire medium pink. so the correct answer is D)Ammonia. 2)The B cell produces antibodies (specialized white blood cells). A B cell multiplies and clones when it comes into touch with an antigen. These cloned B cells, also known as plasma cells, unleash countless quantities of antibodies into our lymphatic and blood systems. So the correct answer is c)B cells. 3)Alpha-naphthol in ethanol makes up the Barritt's A reagent. When detecting the presence of 2,3-butanediol, or so-called "neutral fermentation products," generated from glucose in MRVP broth, it is combined with Barritt's B reagent (40% KOH). so the correct answer is a)alpha naphthol and potassium hydroxide. 5)Coagulase is a protein enzyme that allows fibrinogen to be changed into fibrin by a variety of bacteria. So the correct answer is c)fibrinogen, fibrin.
