The answer is D because the law of matter is to not to change or create
Answer:
1. living s strain= mice dies
2. heat killed s strain= mice live
3. living r strain= mice live
4. heat killed s strain + living r strain= mice die
Explanation:
Options
1. living s strain
2. heat killed s strain
3. living r strain
4. heat killed s strain + living r strain
Solution
It is known that S strain of the pneumococcal bacteria has virulent properties and hence it can kill an organism but when this S strain is heated its virulent factor dies and it becomes ineffective. R strain on the other hand does not possess virulent characteristics and hence it does not affect the mice. If R virulent is mixed with heat killed S strain, the new strain is transformed virulent strain which could kill an organism.
Considering above description, the answer would be
1. living s strain= mice dies
2. heat killed s strain= mice live
3. living r strain= mice live
4. heat killed s strain + living r strain= mice die
