It's been proposed that future space stations create "artificial gravity" by rotating around an axis. (The Space Station would have to be much larger than the present Space Station for this to be feasible.)

a. How would this work? Explain

b. Would the artificial gravity be equally effective throughout the space station? If not, where in the

Space Station would the residents want to live and work?

In 1859, charles darwin published the first edition of on the origin of species, which explained his observations of various groups of animals that showed great similarities but minor differences. darwin concluded that if a population of one species separates into two different populations that live in separate locations, then over the course of many generations the different populations can develop into different species. this idea predicted many future biological findings and became the basis of modern biology. darwin’s explanation for why different species exist is best described as a(n) law. theory. inquiry. hypothesis.
