Many years ago, head lice was easily treated with pyrethrum based pesticides. Pyrethrums are commonly found in products such as Rid that can be purchased at local markets. They are currently the top choice for lice infestations. Pyrethrums are especially useful to us because they generally have a stronger effect on bugs than on humans and animals.
Some head lice had mutations in their genetic code which allowed them to survive the chemical pesticide and they produced chemically resistant offspring. How can this be explained?
Question 26 options:
