Aisha's 8-month-old cocker spaniel is showing some concerning signs. Besides not eating, she tells the vet that he has become almost a completely different pup, hiding in dark corners and snapping at her. He has constant diarrhea and vomiting. As the vet examines Aisha's dog, he asks her how old the home she lives in is. Surprised by the question, Aisha says that it is an older home in the historic area, probably built in the 50s. Why is the vet MOST likely interested in this information?
Older homes can have lead paint, and he believes the dog may have lead poisoning.
A large ranch needs to change the feed that it gives its cattle. The feed they used to give was low in nitrates, but the company has stopped selling it. The new feed is higher in nitrates, so the ranchers do not switch the cattle over all at once. They take a few months to slowly lower the level of old feed, while introducing the new feed. Which sentence BEST explains what the ranchers are most likely attempting to do by adjusting the feed this way?
They are trying to get the cattle to build up a tolerance for nitrates.
