Sedimentary rocks are 'built up' over time, and if something dies overtime, lets say an animal, it will get buried and minerals will fill it and it becomes a fossil. fossils are important because they tell us about the past and what is was like way back when.
there are two or three types or methods in which they change according to the class you study so this a answer from a 8th grader ( there are difference in classes)
<u>Nitriates</u> are a form of <u>nitrogen</u> that is usable by plants.
It is assimilated into plant tissue as protein. The nitrogen is passed through the food chain by animals that consume the plants, and then released into the soil by decomposer bacteria when they die.
Nitrification is the conversion of ammonia (NH3) to nitrate (NO3). It is usually performed by soil living bacteria, such as nitrobacter. This is important because plants can assimilate nitrate into their tissues, and they rely on bacteria to convert it from ammonia to a usable form.
denitrifying bacteria convert nitrogen into ammonia which is a form of nitrogen that is useful to humans. Bacteria "fixes" gaseous nitrogen into nitrogen usable by plants in the form of nitrate.
Answer:
Triple repeat expansion.
Explanation:
Fragile X syndrome is the genetic disorder in which the toxic RNA is produced in the body. This mutation is located on the long arm of the X chromosome.
Fragile X syndrome is also known as trinucleotide repeat disorders. The nucleotide CCG is increased in the affected individual from 200 to 4000. The severity of the disease depends on the repeat of CCG nucleotide in the individual.
Thus, the answer is triple repeat expansion.
There are some factors that influence cancer. Highly the top answer, smoking can DEFINITELY influence the risk because it ruins the lungs. On the other hand, heredity can influence it, too. If you dwell on it, if most of your family members have cancer, then it was passed down from member to member.
