Answer

To determine how many of the provided statements are incorrect, we will analyze each statement one by one.

**Step 1: Analyze Statement i**
- Statement: "Microbes comprise of diverse organisms like protozoa, bacteria, fungi and microscopic plants, viruses, viroids and also prions that are proteinaceous infectious agents."
- Analysis: This statement is correct. Microbes do include a variety of organisms such as protozoa, bacteria, fungi, viruses, viroids, and prions.

**Step 2: Analyze Statement ii**
- Statement: "Microbes like bacteria, viruses and many fungi can be grown on nutritive media to form colonies."
- Analysis: This statement is incorrect. While bacteria and fungi can be grown on nutritive media, viruses cannot be grown on such media alone as they are obligate parasites and require a host to replicate.

**Step 3: Analyze Statement iii**
- Statement: "In our stomach, the LAB plays a very beneficial role in checking disease-causing microbes."
- Analysis: This statement is correct. Lactic Acid Bacteria (LAB) are beneficial microbes that help in maintaining gut health and inhibit the growth of pathogenic microbes.

**Step 4: Analyze Statement iv**
- Statement: "'Toddy', a traditional drink of some parts of southern India is made by fermenting sap from sugarcane."
- Analysis: This statement is incorrect. Toddy is actually made from the sap of palm trees, not sugarcane.

**Step 5: Count the Incorrect Statements**
- From the analysis:
- Statement ii: Incorrect
- Statement iv: Incorrect
- Therefore, there are 2 incorrect statements.

**Final Answer:**
The number of incorrect statements is 2.
