Since the early 1960s, fluoride has been added to many sources of drinking water to prevent cavities in teeth. This is called fl
uoridation. There are some who say that this is unnecessary and increases the risk of cancer. In 1993, the Subcommittee on Health Effects of Ingested Fluoride of the National Research Council, part of the National Academy of Sciences, conducted an extensive study about the link between fluoridated drinking water and increased cancer risk. The study included data from more than 50 human disease studies and six animal studies. The Subcommittee concluded that none of the data showed a link between fluoridated drinking water and cancer. A 1999 report by the CDC supported these findings. The CDC report concluded that studies so far have produced "no credible evidence” of a link between fluoridated drinking water and an increased risk for cancer. According to the article, what valid claim came from the National Research Council? There is no link between fluoride exposure and increased cancer risk in humans. There is a possible link between fluoride exposure and increased cancer risk in humans. There is a definite link between fluoride exposure and increased cancer risk in humans and animals. There is a possible link between fluoride exposure and increased cancer risk in animals.
A. There is no link between fluoride exposure and increased cancer risk in humans.
Explanation
The National Research Council claim was that the data obtained from the extensive study about link between fluoridated drinking water and increased cancer risk did not show the connection. Though studies have been made to investigate the possibility of a link between fluoridated drinking water and increased risk for cancer, no credible evidence has proved any connection.
<span>The tundra and the desert are very similar in one important way. Each of these biomes has low rainfall and available water, this results in plants in each environment that have adapted in similar ways. It causes these plants to have a waxy coating on the leaves which aids in preventing them from drying out.</span>
In place of clicking on the touchpad for the Cases, I would boost
in response to the visual incitements that would be linked with a reflex hammer
with an accelerometer; the reflex hammer would move appropriately to the carrying
of the picture on the screen by a programmed mechanical device. I wouldn’t use
the reflex hammer’s sound however; it’s purely there to compute my reaction
times (time of highest acceleration of movement of the reflex hammer deducted
by time of reflex) instead of using the computer’s software at figuring
reaction times, since I think the software is defective.
