You did not square the radius term on the bottom of the equation. The gravitational force depends on the inverse of the radius SQUARED. When you square the radius and then divide, you get 4.5×108. ...
Remember, there are two theories of gravity: the graviton theory and the general theory of relativity. In the graviton theory, massive object exchange little particles called “gravitons.” This is just like electrically-charged objects exchanging photons (the electroweak force) and protons exchanging pions (the strong f...
Fossil impressions typically preserve the INNER parts of a creature, because the pressure destroys most everything but the bones. For example, if a bird dies and forms a mold or cast, you get its feather imprints, its shape, etc. However, if the bird becomes an impression, you might see some feather impressions, but yo...

In the discussion of the internal test, the text talks about how one must apply Aristotle’s dictum because all ancient documents have difficulties. Thus, the Bible passes that test, but the question asks what tests doe...
Yes, if the cell is already haploid with duplicated chromosomes. After all, the whole point of meiosis I is to take a diploid cell and make it haploid with duplicated chromosomes. The question tells you that the cell is haploid with duplicated chromosomes. If the cell is already like that, meiosis I CANNOT happen. ...
