Answer:
Random mutations led to evolution of pesticide resistance genes in bed bugs.
Explanation:
Random mutations in genome of bed bug imparted them the pesticide resistance. Since the bed bugs having the mutation of pesticide resistance were able to survive under presence of pesticides, this variation was favored by natural selection. The bugs with pesticide resistance transmitted this trait to their progeny. In time, the bed bug population consisted of most of the bugs having the pesticide resistance.
The parasite can live<span> in the environment for many months and contaminate soil, water, fruits and vegetables, sandboxes, grass where animals graze for food, litter boxes, or any place where an infected cat may have defecated. </span>Toxoplasmosis<span> is an infection caused by a microscopic parasite called </span>Toxoplasma<span> gondii.</span>
Answer:

Answer: what I learned is that natural selection needs 4 things
Explanation:
over production
genetic variation
i don’t remember the rest but those are the main ones so that there’s lots of offspring in case some cant survive
