<h3>☣ Question -:</h3>
Which of these equation is the correct one for fermentation?
❍ Glucose + oxygen → carbon dioxide + water
❍ Glucose → lactic acid
❍ Glucose → ethanol + carbon dioxide
<h3>☣ Explanation -:</h3>
To understand this first we should know what is fermentation.
<u>What </u><u>is </u><u>fermentation</u><u>?</u>
A process of chemical change in food or drink because of the action of yeast which may cause it to produce bubbles or heat, or turn sugars in it into alcohol.
<u>Equation -:</u>

Which means
Glucose → ethanol + carbon dioxide
- Hence opition c is the correct answer.
No. Glucose is split by glycolysis before the aerobic parts of cellular respiration, when oxygen enters the process.
Hope this helps!
The correct answer is option (a) Scanning tunneling microscope.
Microscopes are used to see the objects at molecular level. Scanning tunneling microscope( STM) is a type of optical microscope that uses optics(light) and lenses to see the enlarged size of the object. This microscope use a small metal tip under a high voltage. when this tip of microscope is brought close to the metal, the metallic tip of microscope draws electrons from the atom (metal) to be observed. This generates an electric current. There is a computer system attached to the microscope that detects the change in the electric current. Computer plots the change in position of atoms in metal.
