Atoms are made up of a nucleus, protons and electrons. ... Atoms were created after the Big Bang 13.7 billion years ago. As the hot, dense new universe cooled,
weapon ", has only been used in the human history two times, enables the Second World War to become the history actually.The nucleus takes the energy, huge prepares because of its clean reliable also the energy is favored.May say like this that, the nuclear power, uses in the war[...
but we are not afraid but we cant stay near but we finally made t but we let it drift but we neglect to be but we still goes but we will send them but were elite skills but wednesday but welcome it but when expressly ti but when he came to t but when it is evil y but when ...
Nuclear fission occurs when a large and unstable nucleus splits apart into smaller, more stable nuclei. A nucleus is made up of protons and neutrons... Learn more about this topic: Nuclear Fission | Definition, Types & Examples from Chapter...
Earlier scientists had demonstrated that atoms consist of positively charged nuclei surrounded by electrons orbiting like planets, but they couldn't explain why electrons didn't simply spiral into the nucleus. In 1913, Bohr proposed that electrons exist in discrete orbits based on their energy. When...
Neonatal exposure to oestradiol increases dopaminergic transmission in nucleus accumbens and morphine‐induced conditioned place preference in adult female... Steroid sex hormones produce physiological effects in reproductive tissues and also in nonreproductive tissues, such as the brain, particularly in corti...
How is fermium made? Fermium: Fermium is an artificially produced element with 100 protons in the nucleus of the atom. It has 22 isotopes, but the most stable isotope has a half-life of only 100.5 days. Answer and Explanation:1 Today, fermium is produced by bombarding actinide metals with...
By compressing the nucleus of the iron atom, we add energy to its 26 protons and 30 neutrons. If we press hard enough, the protons and neutrons will burst apart into what they're made of: smaller particles called quarks. We'll then have a mess of quarks -- the type of quarks called...
How does the DNA of prokaryotic cells differ from the DNA of eukaryotic cells? How is DNA packaged in the nucleus of somatic cells? How does DNA code for proteins in a cell? What is the DNA structure of eukaryotic cells? How does the structure of DNA allow cells to replicate?
Other advancements are being made in the field of MRI. Functional MRI (fMRI), for example, creates brain maps of nerve cell activity second by second and is helping researchers better understand how the brain works. Magnetic resonance angiography (MRA) creates images of flowing blood, arteries ...
