Potential Explosions
Radiation
Radioactive Waste

Nuclear Fission is not a good source of energy. This is by reason of only 0.7% of the uranium being captured. This is small even if one doesn't mention that only 40% of that 0.7% is converted into usable energy. There are also chances that the power plant could explode during conversion. All of this evidence points to the fact that Nuclear Fission and Nuclear Energy themselves should not be relied on.

Sun and Stars

Uranium and Plutonium
The correct answer is anaerobic exercises. Anaerobic
exercises is an intensely done activity, wherein the body’s call for oxygen goes
beyond the oxygen source accessible within the body. Anaerobic exercises feeds on
the energy sources that are stored in the muscles of the body, which is why it
is the exercise that targets muscle cells for maximum demand of energy.

Answer:
C. Osmosis
Explanation:
Osmosis is the net movement of solvent molecules, usually water, from a region of lower solute concentration to a region of higher solute concentration through a partially permeable membrane. Osmosis is a very useful for moving materials in and out of the cell.
Solutions are mixtures of solutes and solvents. The main aim of osmosis is for all the mixture part to be uniform and the solvent equally dispersed to all the part of the solution.
Osmosis is controlled to a large extent by concentration gradient.
Diffusion on the otherhand is the movement of molecules of a substance from one position to another.
Facilitated diffusion and active transport are just mechanisms for transport within a cell or a body.
Coin flipping simulates the events of mitosis and the production of sperm. This is because females carry XX chromosomes so all eggs will have a singular X chromosome. It is the sperm that determines the sex of the foetus: males have XY chromosomes and therefore sperm will carry either X or Y chromosomes (a 50/50 chance, just like flipping a coin)
