what are the similarities between fission and fusion reactions?

1 Answer. Fusion and fission are similar in that they both release large amounts of energy. Nuclear fusion is a process in which two nuclei join to form a larger nucleus. Nuclear fission is a process in which a nucleus splits into two smaller nuclei.

Binary Fission is a method of asexual reproduction. This process involves splitting the DNA of a parent cell creating two identical daughter cells. Conjugation is a sexual reproduction, it involves the direct transfer of genetic material between two bacterial cells that are temporarily joined.

Nuclear fusion occurs spontaneously, as happens to the C14 used in carbon dating. ... In nuclear fission, a nucleus splits; in nuclear fusion, nucleons or nuclei and nucleons join to form a new nucleus. There is no difference. Fission and fusion are different names for the same physical phenomenon.

The isotopes uranium-235 and plutonium-239 were selected by the atomic scientists because they readily undergo fission. Fission occurs when a neutron strikes the nucleus of either isotope, splitting the nucleus into fragments and releasing a tremendous amount of energy.

Nuclear reaction. In nuclear physics, a nuclear reaction is a process in which two nuclei or nuclear particles collide, to produce different products than the initial particles. In principle a reaction can involve more than two particles colliding, but such an event is exceptionally rare.

The main difference between fission and fragmentation is that in fission, a unicellular organism breaks up to form two daughter organisms whereas in fragmentation, a multicellular organism breaks up into various fragments and each fragment develops into a complete organism.

Fertilisation does not lead to the formation of clones. Hence there is no chance of variation. On the other hand fission is a process by which the parent cell divides into two.

All nuclear power plants use nuclear fission, and most nuclear power plants use uranium atoms. During nuclear fission, a neutron collides with a uranium atom and splits it, releasing a large amount of energy in the form of heat and radiation. More neutrons are also released when a uranium atom splits.

Binary fission occurs when a parent cell splits into two identical daughter cells of the same size. Fragmentation occurs when a parent organism breaks into fragments, or pieces, and each fragment develops into a new organism.

With current technology, the reaction most readily feasible is between the nuclei of the two heavy forms (isotopes) of hydrogen – deuterium (D) and tritium (T). Each D-T fusion event releases 17.6 MeV (2.8 x 10-12 joule, compared with 200 MeV for a U-235 fission and 3-4 MeV for D-D fusion).

Modern nuclear weapons work by combining chemical explosives, nuclear fission, and nuclear fusion. The explosives compress nuclear material, causing fission; the fission releases massive amounts of energy in the form of X-rays, which create the high temperature and pressure needed to ignite fusion.

Both fission and fusion are nuclear processes by which atoms are altered to create energy, but what is the difference between the two? Simply put, fission is the division of one atom into two, and fusion is the combination of two lighter atoms into a larger one. ... Nuclear fission releases heat energy by splitting atoms.

The similarity they have is that they both produce two identical cells to each other and to the mother cell, but the mechanism is totally different as binary fission takes place in prokaryotic cells while mitosis takes place in eukaryotic ones.

(1) Nuclear reactions involve a change in an atom's nucleus, usually producing a different element. Chemical reactions, on the other hand, involve only a rearrangement of electrons and do not involve changes in the nuclei. ... (3) Rates of chemical reactions are influenced by temperature and catalysts.

Fission chain reaction. Fission chain reactions occur because of interactions between neutrons and fissile isotopes (such as 235U). ... These free neutrons will then interact with the surrounding medium, and if more fissile fuel is present, some may be absorbed and cause more fissions.

Nuclear fission products are the atomic fragments left after a large atomic nucleus undergoes nuclear fission. Typically, a large nucleus like that of uranium fissions by splitting into two smaller nuclei, along with a few neutrons, the release of heat energy (kinetic energy of the nuclei), and gamma rays.
