- A paleontologist estimates that when a particular rock formed, it contained 12 mg of the radioactive isotope potassium-40. The rock now contains 3 mg of potassium-40. The half-life of potassium-40 is 1.3 billion years. From this information, you can conclude that the rock is approximately ______________ billion years old.Which item is best dated using the potassium-argon (K-Ar) method? Group of answer choices A: Cave layers in South Africa B: stone tools C: Ancient dinosaur bones D: organic materials E: Lava flows found in the Olduvai GorgeYou've been doing research to help your grandmother understand two new drugs for osteoporosis. One publication, Eurasian Journal of Bone and Joint Medicine, contains articles with data only showing the effectiveness of one of these new drugs. A pharmaceutical company funded the Eurasian Journal of Bone and Joint Medicine production and most advertisements in the journal are for this company's products. In your searches, you find other articles that show the same drug has only limited effectiveness. Pick the best answer that would help you decide about the credibility of the Eurasian Journal of Bone and Joint Medicine: It is a credible source of scientific research because the studies published in the journal were later replicated by other researchers. It is a credible source of scientific research because the publication lists reviewers with appropriate credentials who evaluated the quality of the research articles prior to publication. It is not a credible source of scientific…
