Watson and Cricks
They discovered DNA. the blueprint for all living creatures.

They did not discover DNA. They discovered what form DNA has (a double helix) and that each of the four proteins that make up DNA have a partner. (Adenine with Thymine, Guarine with Cytocine) This was important because now scientists could understand how DNA replicates itself so consistently, because if one strand has the proteins T A G A, the other strand will be A T C T.
When you ovulate your cervix dips down lower in the vagina to try to meet the sperm sooner so that you can get pregnant during pregnancy the cervix is higher up in the vagina and closed completely when you go into labor your cervix will efface (thin out) and dilate (open up) to 10cm this can be an extremely looooong process...hope this answers your question Good Luck and God Bless!! The first part of that answer is incorrect. When you ovulate your cerix is high usually hard to reach, open, and soft like your lips. When ovulation is over and your period is near it drops low and is hard like the tip of your nose. What helps the sperm meet the egg is the egg white cervical mucus that you get during ovulation (if you don't get ewcm try preseed it won't harm the sperm at all). During pregnancy your cervix goes back to its high position, closed, with a plug of cervical mucus covering it to protect unwanted bacteria from entering (although that is not a good sign to use for conception cause it varies with each woman). When you're approaching labor your mucus plug comes out and your cervix is low and open preparing for the birth of your baby.
Yes. They can be made through either fusion or fission. Through fusion, atoms with lower molecular numbers can combine to make one atom of a higher molecular number. This process occurs in stars when hydrogen is fused into helium. In nuclear fission, an atom with a high molecular number, looses neutrons and protons to become an atom with a lower molecular number. It is said to be radioactive, and this happens naturally as uranium turns into lead. When it happens naturally the rate at which it goes through fission is called a half-life. When it is used in a nuclear reactor it can release energy as if undergoes fusion and produce a lot of energy over a long period of time. When it is used in an atomic bomb, the fission undergoes a chain reaction where all the energy is released in a fraction of a second and creates a huge explosion. When it is used in a nuclear bomb, an atom bomb explodes under nuclear fission and then triggers hydrogen to fuse into helium in a secondary explosion. This type of bomb releases even more energy. So. Yes, atoms can be made and destroyed, in both cases huge amounts of energy are released in the process.
About the only measure of performance of this fridge is a comparative one. Here's the story. The Natural Resources Defense Council sponsored a contest back in the early 90's. It challenged appliance manufacturers to design and build a new refrigerator that would work with a refrigerant that was not a conventional, and not an environmentally (ozone) unfriendly, chlorofluorocarbon (CFC). There was a $30 million prize (the "Golden Carrot") that was put up by a group of utilities for the winner. Whirlpool took top honors. It's new machine was about 25% more efficient than the crop of (then) current models. Given that the familiar fridge sucks up about 20% of a household's electricity, the potential for cost savings was high.
(China Syndrome) and ( Silkwood) dealt with Nuclear-power safety issues- quite distinct from nuclear warfare, bomb scares and possible terrorist use.
