If the somatic cells of a human contain 46 chromosomes, then after meiosis new sex cells would contain chromosomes.

23 chromosomes.

Explanation:

Meiosis is a process where a cell divides twice to produce four sex cells containing half the original amount of genetic information. These sex cells are known as gametes, which are sperm in males, and eggs in females.

These gametes are created between the first time the cell divides, called meiosis I, and the second time it divides, known as meiosis II.

Meiosis I separates homologous chromosomes producing two haploid daughter cells cells, which have 23 chromosomes each. Because of this, the ploidy is reduced from diploid to haploid, and meiosis I is referred to as a reductional division. During Meiosis II, sister chromatids are separated, creating four haploid daughter cells.

photosynthesis makes the glucose that is used in cellular respiration to make atp. the glucose is then turned back into carbon dioxide, which is used in photosynthesis. while water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.
