Why does the nuclear envelope break down in prophase?
If the nuclear envelope didn't break down, the spindle would not attach to the kinetochore proteins on the condensed chromosomes in prometaphase because the nuclear envelope would be in the way.
Are the nuclear reactors the same processes occurring in the sun and reactors?
No. The sun produces energy by fusion. It is joining hydrogen atoms into larger helium atoms, which releases energy. Man-made nuclear reactors produce energy by fission. They break large atoms into smaller atoms, which also releases energy.
What technological problems are associated with nuclear power and nuclear fusion?
There is an existing fusion technology that produces controlled amounts of fusion energy - more energy out of the fusion power generating system than it takes to run the fusion power generating system. It might be worthwhile to remember that Ivy-Mike technology worked the very first time it was tried in the 1952 nuclear test. Mike technology was the basis of the first thermonuclear weapons in the US arsenal. Adapting Mike technology to be pure DT-DD fusion opens up many new applications in safe, economical, fusion power generation. While historically practical nuclear fusion has used a small amount of fissionable material like U235 to produce the conditions for fusion - Today, there are smaller pure fusion devices optimized to make clean energy (not blast effects) from hybrid pure DT-DD fusion while producing no radioactive fission products and high level nuclear waste. Modern DT-DD pure fusion devices produce the overwhelming majority of their energy from the DD fusion reaction of Deuterium separated from sea water. One such modern hybrid DT-DD fusion design is called mini-Mike, which produces a small predictable controlled energy yield of 250 GJ per shot. (Since pictures and outside web links are not allowed on Answers) Description of a practical hybrid 2-stage fusion device - mini-Mike is a two stage device that features a small hollow 2 mm diameter Deuterium-Tritium fusion capsule which in turn ignites a column of pressurized Deuterium cryo-liquid resulting in devices with safe and reliable energy yields optimized for power generation. In 60 years, no other fusion technology (Magnetic Confinement or Inertial Confinement) has ever produced any net energy (more energy out of the fusion reaction than it takes to get the fusion plasma to fusion conditions). In 60 years, all existing MCF and ICF fusion systems have never worked (in the sense that they have not produced more energy from fusion than it took to get the fusion plasma to fusion conditions).. Mike technology worked the first time it was tried and produced huge amounts of net energy (and has never failed). Rather than placing our faith in scaling laws while we build ever larger and more expensive fusion experiments while trying to achieve break even energy generation - why not go back to the field and adapt technology that has never failed to finally find success in fusion?
Why nuclear fission is often easier to initate than nuclear fusion?
Nuclear fission involves splitting heavy atoms, like uranium, which releases energy. This process is easier to initiate because it requires less extreme conditions, such as lower temperatures and pressures, compared to nuclear fusion. Fusion involves merging light atoms, like hydrogen isotopes, which requires much higher temperatures and pressures to overcome the electrostatic repulsion between the positively charged nuclei.
What is the difference between nuclear fusion and nuclear fusion?
Nuclear fission is the breakup of an atom. In nature this is usually spontaneous, but in nuclear reactors it is almost always caused by the absorption of an extra neutron.Nulcear fusion is the combination of two (or more, but almost always two) atoms to form a new atom.Fusion is where you take to atoms and combine them together with enough heat to fuse them and create another atom + neutron + released energy.Fission is where a neutron is fired at an unstable large atom nuclei to cause it to break down into two smaller nuclei and 2 - 3 more neutrons, also releasing energy.At the moment, on earth, we use nuclear fission is nuclear power stations as it does not need a high temperature to overcome the repelling nature of the two positively charged nuclei in fusion.Nuclear fission is splitting an atomic nucleus into smaller particles, including at least one new nucleus.Nuclear fusion is forcing two atomic nuclei together to form one atomic nucleus.
Why does the nuclear envelope break down in prophase?

Who decided the restoration?
Atoms break by human power as well as naturally. Atoms break constantly as part of nature but they also are broken through man made processes like nuclear fusion.
Will the sun break up into small parts?
No. The sun is firmly held together by gravity.
Are the nuclear reactors the same processes occurring in the sun and reactors?
No. The sun produces energy by fusion. It is joining hydrogen atoms into larger helium atoms, which releases energy. Man-made nuclear reactors produce energy by fission. They break large atoms into smaller atoms, which also releases energy.
What are some attributes of nuclear fission?
Nuclear fission (as opposed to nuclear fusion) is the process in which a atom is broken into smaller pieces (other smaller atoms). This is different from nuclear decay, in which an unstable particle emits particles in an attempt to become more stable. Nuclear fission can be done on any element, other then hydrogen, however it will not yield energy for anything smaller then Iron. When a large particle, like Uranium, is broken into fissile elements, they don't always break the same way. So you would not always get the same particles. These fissile particles fly off and strike another atom, and break it into pieces and the reaction continues.
Is radioactive decay a source of sun's energy?
No. The Sun is powered by nuclear fusion, primarily of hydrogen into helium. Radioactive decay is sort of the reverse process, in which a heavy element will break down into lighter ones.
What makes up a nuclear bomb?
Depends on the type of bomb. The first nuclear weapons were fission weapons- they used a heavy metal such as Uranium or Plutonium. These metals, when compressed by explosives, would undergo nuclear fission, and break into lighter elements, releasing heat and radiation. Later, larger bombs were fusion bombs. They used a fission bomb to start the nuclear reaction, but then used that energy to FUSE light elements, such as Deuterium and Tritium into heavier elements, releasing LARGE amounts of heat and radiation.

Was the sun formed with nuclear fussion?
There are two similar words to describe nuclear reactions. Fusion, in which smaller atoms are fused together to produce energy, and fission, in which giant atoms are caused to break apart, also releasing energy. Similar, but opposite. The Sun, and all the stars, form using fusion, in which atoms of hydrogen merge to form atoms of helium. For old stars that have used up much of their hydrogen, helium atoms can fuse again to become carbon or oxygen. Fission power is similar to the nuclear powerplants here on Earth, in which uranium atoms break apart into lighter elements.
What are the release dates for Break It Down - 2008 Nuclear Submarine?

What would happen if you spill sulphuric acid?
A massive nuclear war would break out destroying the continets and killing off life as we know it.
What is the difference between the atomic bomb and hydrogen bomb?
The difference between an A-Bomb and H-Bomb is the energy reaction inside them, one of them is nuclear fusion and the other one is nuclear fission. A-Bombs contain a unstable nuclei such as Uranium 235, whiles H-Bombs contain light stable isotopes of hydrogen and sometimes helium. Nuclear fusion is the merging of atoms/particles, whilst nuclear fission is the splitting and break down of a big unstable nuclei.
