Answer to Question 1

As a molecular cloud contracts, it breaks up into fragments and can form many protostars. Gravity can pull two neighboring protostars closer together but conservation of angular momentum prevents them from directly crashing into each other and instead they can end up orbiting each other as a binary.

Answer to Question 2

The era of nucleosynthesis is important because during this time, all the primordial hydrogen and helium was created by nuclear fusion. Except for the few percent of matter that stars later fused into heavier elements, the chemical composition set in the nucleosynthesis era remains unchanged today.

Drug abusers experience the following scenario: The pleasure given by their drug (or drugs) of choice is so strong that it is difficult to eradicate even after years of staying away from the substances involved. Certain triggers may cause a drug abuser to relapse. Research shows that long-term drug abuse results in significant changes in brain function that persist long after an individual stops using drugs. It is most important to realize that the same is true of not just illegal substances but alcohol and tobacco as well.

Although the Roman numeral for the number 4 has always been taught to have been "IV," according to historians, the ancient Romans probably used "IIII" most of the time. This is partially backed up by the fact that early grandfather clocks displayed IIII for the number 4 instead of IV. Early clockmakers apparently thought that the IIII balanced out the VIII (used for the number 8) on the clock face and that it just looked better.

A serious new warning has been established for pregnant women against taking ACE inhibitors during pregnancy. In the study, the risk of major birth defects in children whose mothers took ACE inhibitors during the first trimester was nearly three times higher than in children whose mothers didn't take ACE inhibitors. Physicians can prescribe alternative medications for pregnant women who have symptoms of high blood pressure.
