The result of meiosis is that the offspring will have no genetic variation, which means that it has less of chance for surviving changes to the environment. What happens to the chromosomes is that they duplicate and homologous chromosomes exchange genetic information (chromosomal crossover) during the first division, called meiosis I. The daughter cells divide again in meiosis II, splitting up sister chromatids to form haploid gametes.
In fixation, the first stage of the Calvin cycle, light-independent reactions are initiated; CO2 is fixed from an inorganic to an organic molecule. In the second stage, ATP and NADPH are used to reduce 3-PGA into G3P; then ATP and NADPH are converted to ADP and NADPH+

Answer:
Solar Energy
Explanation:
The table is about renewable and non renewable natural resources which may or may not pollute the environment. Natural gas and wind are the renewable energy resources which do not adversely affect the environment. Coal is non renewable energy resource that release harmful gases into the air upon burning. Solar energy is another example of renewable resource that do not pollute the environment.
