<span>Nuclear reactors generate energy through fission, the process by which an atomic nucleus splits into two or more smaller nuclei. During fission, a small amount of mass is converted into energy, which can be used to power a generator to create electricity. In order to harness this energy, a controlled chain reaction is required for fission to take place. When a uranium nucleus in a reactor splits, it produces two or more neutrons that can then be absorbed by other nuclei, causing them to undergo fission as well. More neutrons are released in turn and continuous fission is achieved.</span>
A river of air called the jet stream runs along the troposphere just near the top. The troposphere starts at ground level and rises 11 km up which is equivalent to 7 miles or 36,000ft.
About 3/4 of the air in our atmosphere is in the troposphere and almost all weather happens here. Most of the clouds are found in the troposphere layer.
The jet stream is found just near the top of the troposphere zooming along at a speed of 400km/hr (250 miles per hour)
B , because there is more than one path of energy coming from the plants but if it’s not B then it’s A because arrows that are all over the place is what makes it a web
Clearly the onion cell consists of a cell wall, because an onion is a multicellular plant organism.
Multicellular means; consisting of many cells.
