Which of these statements best describes the connection between biodiversity and evolution?
The more biodiversity an area has, the greater the chances of new species arising.
If biodiversity is high, then more predation will take place, preventing species from evolving.
Without a lot of biodiversity, organisms are more likely to survive, so they have more time to adapt.
Evolution depends upon low biodiversity to keep population sizes down, which increases numbers of genes.

The hypothesis that the continents once formed a single landmass, broke up and drifted to their present location is either:

A) How long will it take for 40.0 grams of Radium-226 (Ra-226) to decay to leave a total of 2.5 grams of Ra-226? Ra-226 has a half-life of 1600 years.
