To describe the process whereby bacteria on the teeth metabolize carbohydrates producing tooth-damaging acids is used the term tooth (or dental) decay. It is a tooth demineralization process that occurs when a tooth is exposed to an acidic environment of pH 5.5 and below. The primary food source for cariogenic (cavity-causing) bacteria is dietary sugars.Suggestion is to b<span>rush and floss promptly after eating so to insure that dental plaque is not present on your teeth.</span>
Answer:
Biodiversity will be highest when: Dispersal rates of species are high.
Explanation:
Dispersal increases the chances of having biodiversity as it helps the spread of biodiversity across the globe
Answer: They are not regulated by contact inhibition.
Explanation:
Contact inhibition is a form of controlling cells. Cancer doesn't have contact inhibition, which is one of the reasons why it spirals out of place so easily.
Answer:
The average size of the DNA fragments produced when this new DNA is cut by a restriction endonuclease with an eight-base recognition sequence would be 1679616.
Explanation:
Restriction enzymes can be described as the enzymes which are specific to certain DNA sites and cut the DNA from that particular site.
Normally, the average size of a DNA fragment cut by a restriction enzyme is calculated by the formula 4^{no.of base recognition sequence}.
As the number of bases has changed to 6 and the restriction enzyme has eight base recognition site then the formula will be:
6^{no.of base recognition sequence}
i.e
6^{8} = 1679616
