A large population of Japanese beetles infests a plot of cropland. In response to the infesta tion, farmers treat the land with organochlorine pesticides. As a result of the treatment, the population of Japanese beetles is eradicated within the cropland, along with the popula- tions of multiple other insect species. Which of the following statements explains the most likely reason for the death of so many insect populations? Organochlorine pesticides are persistent organic pollutants that interfere with the respi- ratory system of the insect populations. Organochlorine pesticides are endocrine disruptors that interfere with the growth hor- mones of the insect populations. Organochlorine pesticides are persistent organic pollutants and interfere with the re- productive organs of the insect populations. Organochlorine pesticides are endocrine disruptors that interfere with the transmission of nerve impulses, resulting in spasms, seizures, and death of the insect populations.

Before slow cooking a meat (for example, in a crockpot/slow-cooker) you will often find instructions to sear the meat on high heat in an oiled skillet for a few minutes before transferring it to the crockpot. The searing is brief – not long enough to cook the meat thoroughly. Despite myth/legend, the searing will not “seal in the juices”. What is the searing for?
