Answer:
S phase is called as DNA synthesis phase.
In G1 Phase the DNA replication Begins.
During G2 phase cell grow rapidly and protein is synthesized and cell prepares itself for mitosis.
During Mitotic (M) phase, cell division occur.
spermatogenesis is the process during which the production of male sperms occur.
In oogenesis the female egg is produced. Further explanation in attached figures.
The products of one process are the reactants of the other. Notice that the equation for cellular respiration is the direct opposite of photosynthesis: Cellular Respiration: C6H12O6 + 6O2 → 6CO2 + 6H2O. Photosynthesis: 6CO2 + 6H2O → C6H12O6+ 6O.
They are constantly contributing to the scientific community and
improving it. There are always new things to be discovered and they are
constantly doing just that?
