Many human skin tumors contain mutated p53 genes that probably result from excess UV exposure. One of 10 different equally likely mutations of the p53 gene always results from a single episode of excessive UV exposure; the 10 mutations remain equally likely over repeated exposures. A p53 gene must experience all 10 mutations before a tumor can develop. Assume that only one mutation can occur as a result of one excessive UV skin exposure. Question 2. How many excessive UV exposures would you expect are required until the p53 gene has experienced all 10 mutations

im not in connections yet but i might can you some questions. what grade are you in?

the relative atomic mass of an element is the mass of one atom of that element, relative to 1/12th of the mass of a  1212c atom. to convert to an absolute mass in kg, it is necessary to multiply by  1.661×10−271.661×10−27.

the relative atomic mass is roughly equal to the number of neutrons, plus the number of protons, in the nucleus of the atom.

for elements with more than one stable isotope (different types of nucleus with different numbers of neutrons but the same number of protons), the quoted mass is usually the average mass, weighted by the relative abundance of the different isotopes.

bal is blood alcohol level. bac will normally be higher in a person with more body fat. so the answer to your question would be, as body fat decreases, the increasing rate of bal decreases.
