*The rate at which radioactive decay occurs.
*How much radioactive decay has occurred.
Radiation can damage DNA. This could result in a change in the proteins which make up the plant's physical structure.
<span>For example, a plant might have a gene for purple pigment which makes its flowers purple. Radiation might change the DNA sequence so that the directions for making the purple pigment tell it to stop prematurely, and the result might be white flowers rather than purple flowers.</span>
<span>The balanced equation for ammonia (NH3) is 3H2 + N2 ď 2NH3. This equation starts from H2 + N2 ď NH3. We have 1 N and 3 H on the right side (the product side) of the equation, so we multiply each by 2 to get 2 N and 6 H. We do this so that we don’t have an odd number of H atoms. We then balance the left side (the reactant side) of the equation with the right side, N is already balanced, but we have to multiply H by 3 to get 6 H atoms (to match the right side of the equation.</span>
