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.

If 1.0 cup of whole milk contains 290 mg of calcium and milk is his only source of calcium source, how much milk should an 18-year-old male drink each day in mL? Suppose the child is lactose intolerant, do some research and explain what type of milk would be a good substitute for the child. Please give mg of calcium per cup of alternative milk value, and show calculations for how much of the alternative milk an 18-year-old male should drink each day in mL. (Hint: 1 cup = 236.588 mL) Show all work. Give numerical answers in 2 significant figures.II. b) What is the difference between liquid-liquid, solid-liquid and solid-phase extraction?

A 190 lb worker in a factory received an exposure to AB which has a molecular weight (MW) of 278 g/mole. AB is completely metabolized in the body to A (MW 194) and B. A is completely excreted in the urine and B is further metabolized to five different compounds. A 24-hr total urine sample was 2060 ml, Analysis showed the concentration of A in the urine was 1.28 ng/mL What was the absorbed dose of AB in ug/kg body wt?
