Question:
On the basis of descending density which of the following is true?
On the basis of descending density which of the following is true?
Show Hint
Density order:
Spore formers > Non-spore formers > Skim milk > Whole milk.
Used in centrifugal separation.
Spore formers > Non-spore formers > Skim milk > Whole milk.
Used in centrifugal separation.
Updated On: Aug 18, 2026
- Non-spore forming bacteria > spore forming bacteria > skimmed milk > whole milk
- Skimmed milk > whole milk > non-spore forming bacteria > spore-forming bacteria
- Whole milk > non-spore forming bacteria > spore forming bacteria > skimmed milk
- Spore forming bacteria > non-spore forming bacteria > skimmed milk > whole milk
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding the Concept:
Different materials have different densities.
Centrifugal separation depends on density differences.
Step 2: Key Formula or Approach:
No specific formula.
Need to know the densities of these components.
Step 3: Detailed Explanation:
Spore-forming bacteria have the highest density.
Non-spore forming bacteria have lower density.
Skimmed milk is denser than whole milk.
Thus, the descending order is:
Spore forming bacteria > non-spore forming bacteria > skimmed milk > whole milk.
Step 4: Final Answer:
The correct descending order is spore forming bacteria > non-spore forming bacteria > skimmed milk > whole milk.
Hence, the correct option is (D).

Skimmed milk is denser than whole milk.
Thus, the descending order is:
Spore forming bacteria > non-spore forming bacteria > skimmed milk > whole milk.
Step 4: Final Answer:
The correct descending order is spore forming bacteria > non-spore forming bacteria > skimmed milk > whole milk.
Hence, the correct option is (D).
