Answer:
Neutron-capture inside stars.
Explanation: Although there are other minor contributions they are not only produced in stars that explode in supernova.
The cytoplasm functions to support and suspend organelles and cellular molecules. Many cellular processes also occur in the cytoplasm.
Some of these processes include protein synthesis, the first stage of cellular respiration known as glycolysis, mitosis, and meiosis. In addition, the cytoplasm helps to move materials, such as hormones, around the cell and also dissolves cellular waste.
If CO2 was in very small amounts then it would be the limiting factor of photosynthesis, this means the process will take place at a much slower rate because it is lacking one of the raw materials it needs for the process to occur. To find the optimum light intensity you really need all other factors to be at optimum levels or in abundance.
If you are talking about a chemical solution..Yes!
There are many colors a solution can end up being.
