A scientist kept 1,000 gram samples of radioactive thallium, sodium, and rhodium in three different containers. The table below shows the half-lives of the Radioactive Material
Half-life (in hours)
73
thallium-201
sodium-24
rhodium-105
15
35
Based on the table, which of these conclusions is most likely correct? (1 point)
After 45 hours, the amount of sodium left in the container will be 125 gram.
After 45 hours, the amount of sodium left in the container will be 250 gram.
After 70 hours, approximately 500 gram of thallium and rhodium will be left in the containers.
After 70 hours, approximately 125 gram of thallium and rhodium will be left in the containers.

Mike was adopted, and his biological family history is unknown. although he is healthy, he would like some understanding of his genetic makeup, including potential health risks and genes that he could pass on to his children. mike has heard about commercial laboratories that can compare segments of your dna to those of people with common hereditary diseases in order to give you some idea of how susceptible you are to the diseases. the results of these types of tests are highly inconclusive. if mike's dna showed that he shares similarities in a segment of dna with people who have a given disease, his chances of developing that disease or passing it on to his children may be slightly elevated, but they are not 100 percent. these tests can cost more than $2,500 and are not covered by many insurance companies. do you think that mike should undergo the genetic tests? explain your answer. what are the potential pros and cons of having such tests done? describe how the availability of these genetic tests might affect the frequency of genetic diseases in individuals and populations.
