Answer:
"A frameshift mutation is a type of mutation involving the insertion or deletion of a nucleotide in which the number of deleted base pairs is not divisible by three. "Divisible by three" is important because the cell reads a gene in groups of three bases. Each group of three bases corresponds to one of 20 different amino acids used to build a protein. If a mutation disrupts this reading frame, then the entire DNA sequence following the mutation will be read incorrectly."
Explanation:
-if it is a website, look for .gov.
-look for direct facts, never trust opinions.
-they must have cited evidence, if its not cited it can't be trusted.
<span>Unlike the methods of early scientists, Sir Francis Bacon believed basic laws of science should be determined by using inductive reasoning based on empirical evidence. You cannot formulate a law in science if you don't have evidence to support it - so you cannot just take a basic truth and formulate your law based on that - there has to be some kind of evidence to prove your theories. Also, based on those evidence, you will induce a conclusion necessary for such laws, which is something Bacon understood, unlike early scientists.</span>
the actual CORRECT answer is change.
So,
The environment needs to [change] in order for natural selection to occur.
Don't worry i took the test trust me!
