Does Carson believe that natural or human-caused cancers are more prevalent in modern society?
What is the first specific carcinogen she discusses in this chapter? What evidence does she present for an
increase in cancer rates? Is it convincing? How much evidence does Carson present for the
carcinogenicity of pesticides in humans and animals? What happened with the new synthetic pesticide
used against mites and ticks? What happened during the "cranberry scare" of 1959? Why does Carson
believe that we are not able to yet gage the "full effect of the new" pesticides? How is leukemia different
from most cancers? How has the leukemia rate changed over the decade of the 1950s? What examples of
pesticide-induced blood disorders does Carson present? Notice (again) Carson's comparison of the health
effects of radiation (including the Lucky Dragon episode) and chemicals.

Radiometric dating is used to tell the absolute age of materials by studying the decay rate of radioactive isotopes. the decay rates of isotopes are constant and are expressed as .

In 1959, doctors began using the powerful antibiotic methicillin to treat infections of staphylococcus aureus, but within two years, methicillin-resistant strains of s. aureus (mrsa) appeared. how did the resistant strains of s. aureus emerge? in 1959, doctors began using the powerful antibiotic methicillin to treat infections of staphylococcus aureus, but within two years, methicillin-resistant strains of s. aureus (mrsa) appeared. how did the resistant strains of s. aureus emerge? staphylococcus aureus bacteria that were able to synthesize cell walls using a protein that was not affected by methicillin survived the methicillin treatments and reproduced at higher rates than did other individuals. over time, these resistant individuals became increasingly common. in response to treatment of staphylococcus aureus infections with methicillin, some bacteria began to synthesize cell walls using a protein that was not affected by methicillin. these bacteria survived the methicillin treatments and reproduced at higher rates than did other individuals. over time, these resistant individuals became increasingly common. in response to treatment of staphylococcus aureus infections with methicillin, bacterial populations gradually began to synthesize cell walls using a protein that was not affected by methicillin.

Ialready know the answers to these questions and they are on the attachment. but i just need to know why that answer is the correct one. plz asap! this is for a report that i need to email by 10!
