<span>If I were attempting to date a rock sample that I suspect to be incredibly old, i would use radioactive isotopes with a long half life. When dating rocks and fossils to discover approximately how old they are, radioisotope dating is used on igneous rocks found near fossils. Things like Uranium 235, which is an unstable radioactive isotope of elements, decays at a constant rate over time so can be useful in determining age.</span>
<span>Light energy has to be converted into chemical energy in ATP molecules. Plants change light into sugar molecules and both plants and animals change sugar into ATP molecules, which allows for our survival</span>

Answer:
The correct answer will be- light independent reaction or Calvin cycle
Explanation:
The process of photosynthesis takes place in the two phases: light-dependent and light-independent phase.
The light-dependent phase form NADPH and NADPH which are utilized during the light-independent phase to synthesise glucose molecule.
The light-independent phase occurs in the cytosol or stroma of the chloroplast in dark conditions which help synthesize the glucose molecules. The light-independent reaction is also known as the Calvin cycle which forms the glucose molecules in three steps- carboxylation, reduction and regeneration.
Thus, the Calvin cycle is the correct answer.
Answer:
No, if water is not evaporated, it doesn't affect fishes. Fishes need water for its survival and growth. If water is evaporated from fish tank, the quantity of water is reduced in the tank and fish life is in danger if all water is evaporated. If water is not evaporated from fish tank, it is good for fish growth and development.
