The diagram shows an experiment to investigate the respiration of yeast. Oilprevents oxygen entering the glucose and yeast suspension.If no oxygen is present in the glucose and yeast suspension, what will occur?A Ethanol will be produced and the limewater will stay clear.B Ethanol will be produced and the limewater will go cloudy.C Lactic acid will be produced and the limewater will stay clear.D Lactic acid will be produced and the limewater will go cloudy.

The diagram shows some apparatus used to investigate respiration. Yeast, warmwater and substance Z were put into a test-tube. After a while, the limewater began togo cloudy.What is substance Z?A alcoholB glucoseC nitrogenD oxygen

In the experiment below, yeast cells are producing ethanol by anaerobic respiration. What is produced in animal cells?

Ashish took some sugar solution and added yeast to this. He took this mixture in the test tube-A fitted with one-holed cork and fitted the cork with a bent glass tube. He dipped the free end of the glass tube into the test tube-B containing freshly prepared lime water. Which of the following changes would not be observed by him after few hours?One/More correct answer(s)A.Lime water in test tube-B turns milky B.Carbon dioxide and lactic acid are produced in test tube-AC.Glucose is broken down into ethanol and carbon dioxide in test tube-AD.Lime water will remain same as a clear solution

In a scientific investigation of yeast fermentation, formulate a hypothesis that explains the impact of sugar concentration on the rate of anaerobic respiration.

The given diagram shows some events of anaerobic respiration.Which process and by-product formation occurs at X and Y, respectively?X YA Glycolysis Carbon dioxideB Glycolysis WaterC Alcoholic fermentation Carbon dioxideD Alcoholic fermentation Wate
