The correct answer would be Fluoride was not used to help protect teeth then
Cavity is not a genetic disease and thus there is no relevance of gene transfer in this case. Thus option A, B and D gets ruled out.
However, flouride in a limited amount is very useful for removing the cavities. Flouride in the foood and water enters the blood stream and make the teeth strong from inside. While the Flouride in Saliva make the teeths stronger and cavity free from outside. It reduces reminization that causes the loss of minerals.
Thus lack of flouride makes the teeth more cavity prone.
Answer:
While trying to conserve water, we can boil it or purify it through water purifiers so that it may be recycled.
Explanation:
1. PH of 3. As you can see, this is where the enzyme is at 100%
2. The probable PH for enzyme A between 1.5-2.5 as the stomach requires a very acidic pH to maintain digestive health
3. Enzyme A does not work at a PH of 6
4. Enzyme B is working at its maximum rate at a PH of 8
5. The probable PH of enzyme B is 5.5-7.0 as Luminal pH in the proximal small bowel ranges from 5.5 to 7.0
6. If enzyme A were produced in the intestine it would not carry out its usual function of digestion. Not only would the stomach acid likely cause damage to the intestine, a PH closer to neutral is required for absorption of nutrients to occur
