4. </span><span>A chromosomal deletion mutation
5. </span>The mutagens that result in cancer damage DNA by (b) weakening the DNA strand or interfering with base pairing. This mutagens are called carcinogens, if they cause a damage to a gene that makes a DNA repair protein, it means that a cell will have less ability to repair itself, and ,as a result, this will lead to formation of cancer.
<span>human activity influences the natural environment producing negative, direct or indirect, effects that alter the flow of energy, the chemical and physical constitution of the environment and abundance of the species.</span>
