The most serious type of accident which could occur at a nuclear power plant is <span>core meltdown caused by a failure of water to circulate among the fuel rods.
This is what happened in F.ukushima, Japan, in 2011, after a series of devastating earthquakes and tsunamis. This is why F.ukushima is still experiencing extremely high levels of radiation and parts of that area cannot be inhabited anymore.

Answer:
H₃O⁺ and Cl⁻
Explanation:
Hydrochloric acid, a strong acid will ionize completely in solutions.
When acids ionize in water, they produce excess hydroxonium ions in such solution.
HCl + H₂O → H₃O⁺ + Cl⁻
The HCl and H₃O⁺ forms a conjugate pair and likewise the H₂O and Cl⁻
In this ionization, water acts as the base.
Two chromosomes in a pair – normally one inherited from the mother and one from the father. For example, the two copies of Chromosome 1 in a cell would be referred to as homologous chromosomes.
Answer:
During photosynthesis, plants take in carbon dioxide (CO 2) and water (H 2 O) from the air and soil. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose.
Explanation:
The energy for photosynthesis comes from light. Light energy is converted to chemical energy by chlorophyll. There are two sets of reactions, light dependent and light independent. The process mostly takes place in the chloroplasts of plant leaf mesophyll cells. Photosynthesis is the process where a plants uses the sun’s energy to turn light into chlorophyll. Plants produce oxygen during this process and utilize carbon dioxide. Photosynthesis is the single most important chemical process on the earth. Almost all plants needs the sun in order to survive Photosynthesis is the most important chemical process on earth – it provides food and energy for all living creatures who eat the plants that rely on this process to produce their food (glucose). · More than half (70%) of the world’s oxygen is produced by phytoplankton photosynthesis in the world’s oceans.
