The answer is spontaneous mutation .
Sometimes genes, for no known reason(s), change their form in a process called spontaneous mutation.
Mutation is the actually the alteration of the nucleotide sequence of the genome of an organism, virus, or other genetic elements permanently.
Spontaneous mutation : It is a process in which gene automatically for no reason change their form.
Answer:
- <em>The addition of a small amount of HCl to a solution containing fluoride ions and hydrogen fluoride</em> <u>will cause the equilibrium shift to the production of more hydrogen fluoride.</u>
Explanation:
The solution containing <em>fluoride ions and hydrogen fluoride</em> (a weak acid) may be chemically represented by this equilibrium equation:
- F⁻ (aq) + H⁺ (aq) ⇄ HF (aq)
The <em>HCl</em>, a strong acid, added will ionize in water according to this chemical equation:
- HCl (aq) → H⁺ (aq) + Cl⁻ (aq)
Then, following Le Chatelir's principle, the addtion of H⁺ ions coming from the HCl dissociation, will increase the concentration of H⁺ in the solution, driving to the consumption of some F⁻ ions, and the production of more HF acid. This is a shift of the equilbrium toward the HF side.
Answer:
An independent variable is defines as the variable that is changed or controlled in a scientific experiment. It represents the cause or reason for an outcome. Independent variables are the variables that the experimenter changes to test their dependent variable.
