) A scientist kept 1,000 gram samples of radioactive carbon, radium, and plutonium in three different containers. The table below shows the half-lives of the three radioactive materials. Radioactive Material Half-life (in years)

carbon 5,700

radium 1,620

plutonium 6,563

Based on the table, which of these conclusions is most likely correct? (1 point)

After 6,000 years, approximately 250 grams of carbon and radium will be left in the containers.

After 20,000 years, approximately 500 grams of carbon and plutonium will be left in the containers.

After 6,000 years, approximately 500 grams of carbon and plutonium will be left in the containers.

After 20,000 years, approximately 250 grams of carbon and radium will be left in the containers.

parasites can detrimentally affect their host, but also must not allow their host to die before they can complete their life cycle. some parasites have complex life cycles with many different hosts, and have had to find ways of persisting in many different environments during the change from one host to another. ectoparasites live outside the body of the host, and can more easily  disperse, but are  more exposed to predators, parasites, parasitoids. endoparasites live inside the body of the host, and are therefore protected from the outside environment. but they can be  attacked by the host's immune system. they have therefore developed  mechanisms for dispersal such as  complex life cycles.

well

explanation:

scientists have discovered that hiv does not cause aids by the virus's direct effect on the host's immune cells, but rather through the cells' lethal influence on one another. researchers from the gladstone institutes have revealed that hiv does not cause aids by the virus's
