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.
Explanation:
Bedbugs are parasites that rely on blood to survive. They can feed on the blood of any mammal, although they appear to prefer the blood of humans. They are attracted to the warmth surrounding mammalian bodies and the carbon dioxide present in breath expiration. It is usually these factors that guide bedbugs to locate a suitable host for feeding. DOES THIS HELP?

Answer:
Friend (endotherm) will need to eat more calories than snake (ectoderm) to maintain constant body temperature.
To generate heat endotherms convert the food they eat into energy through the process called metabolism. Most of the food that the endotherms eat is converted into fuel to maintain a constant body temperature. Endotherms need to eat more food than ectoderms of the same size to maintain their constant body temperature.
Explanation:
The species had the same fundamental niche, but the high-altitude species was occupying a perceived niche, as it was inhabiting a different ecosystem, with different adaptations, but being the same species.
<h3>Why is the perceived niche considered a subset of the fundamental niche?</h3>
Well, as we know, the perceived niche is smaller than the fundamental niche, in other words it is a specific portion of the fundamental niche, so it is considered a subset of the fundamental niche.
With this information, we can conclude that the species had the same fundamental niche, but that the high-altitude species was occupying a perceived niche, as it was inhabiting a different ecosystem, with different adaptations, but being the same species.
