Pure chlorine is an example of an element.
An element is a chemical substance that cannot be broken down into simpler components in a chemical reaction or by any chemical means, and is made up of atoms that all have the same number of protons. Pure chlorine is an example of an element because it contains only one kind of an atom. Chlorine is a toxic, green, gaseous chemical element. Chlorine is a halogen, has an atomic number of 17, symbol Cl and is found in group 17 in the periodic table. Chlorine is highly reactive and a strong oxidizing and disinfecting agent.
B) decrease genetic diversity
Genetic Diversity refers to vast differences in genetic makeup (genotype) and thus often phenotype as well. The more that extreme genes/traits are excluded in survival and/or reproduction, leading to stabilizing selection, then the more genetically "same" or similar the population will evolve to long-term. Similarity is the opposite of diversity. Thus A) is dead wrong, B) is accurate, and both C) & D) are incorrect because "rare" means not common or "extreme." And extreme traits are exactly what decrease through stabilizing selection.
Hope that this.helps! :)
If the environment is radioactive it can.
Example of radioactive genetic mutation ^^
Also if the environment has been polluted it can too.
Example of pollution genetic mutation would be a frog born with extra legs from living in a polluted pond
Explanation:
a it is not double stranded
