The erosion or disintegration of rocks, building materials, etc., caused by chemical reactions (chiefly with water and substances dissolved in it) rather than by mechanical processes. HOPE THIS HELPS!! :)
<span>The half-life of a radioactive isotope describes the amount of time that it takes half of the isotope in a sample to decay. In the case of radiocarbon dating, the half-life of carbon 14 is 5,730 years. This half life is a relatively small number, which means that carbon 14 dating is not particularly helpful for very recent deaths and deaths more than 50,000 years ago. After 5,730 years, the amount of carbon 14 left in the body is half of the original amount. If the amount of carbon 14 is halved every 5,730 years, it will not take very long to reach an amount that is too small to analyze. When finding the age of an organic organism we need to consider the half-life of carbon 14 as well as the rate of decay, which is –0.693.</span>
Answer: Option B is incorrect rest all the statements are correct.
Explanation:
A single trait can be controlled by multiple genes: A single trait can need multiple gene to be controlled. There are many traits in the body which can be controlled by the multiple genes in the body.
A single trait can alter multiple genes: The activity of a single gene can alter the activity of the multiple genes of the body. The faulty protein produced by the gene can also effect the other genes of the body.
A single gene can influence multiple traits: A single gene in the body can affect multiple characters of the body. A single gene can be responsible or eye color, hair color, skin color et cetera.
