Answer: geosphere and biosphere
Explanation:
The geosphere is the part of the earth which lies below the earth crust. The biosphere is the sphere where all living beings survive.
According to the given situation, the ocean is interacting with the geosphere and biosphere. This is because of the fact that the earthquake emerged in the undersurface of the ocean is the part of the geosphere. The waves produced due to instability of the undersurface resulted in high speed waves. These waves resulted in drastic floods. The floods caused the destruction of the property of the coast, inland areas, plants and animals which came in contact with the flood. Hence, the biosphere was affected.
Answer:
c. each primary spermatocyte produces 4 gametes while each primary oocyte produces one gamete.
Explanation:
The primary spermatocytes are the diploid cells that enter the process of meiosis during spermatogenesis. Meiosis-I in one primary spermatocyte produces two haploid secondary spermatocytes. Both of these secondary spermatocytes enter the second meiotic division and form a total of four spermatids.
On the other hand, the primary oocyte enters the process of oogenesis and gives rise to one secondary oocyte and a first polar body. Both of them are haploid. Meiosis-II in the secondary oocyte forms an egg cell and second polar body. Therefore, only one female gamete is produced by one primary oocyte.
