  • Waiting for answer How is metaphase distinguished?

    Now, during metaphase — the second stage of in the eukaryotic cell cycle — the chromosomes, pulled by the spindle fibers, line up along the middle of the cell, halfway between the centrosomes in the middle of the dividing cell. The chromosomes are now maximally condensed. It is very easy to see th...

  • Waiting for answer How are electric forces and charge related?

    The force between to point charges is calculated by : ##F = (kQ_1Q_2)/(r^2)## where ##Q_1## and ##Q_2## are the two charges in coulombs, k is the Coulomb constant (##8.9875 times 10^9 (N*m^2)/(C^2)## ) , and r is the distance between the centers of the two charges in meters. One charge creates a...

  • Waiting for answer Where does meiosis occur in the human body?

    It produces sex cells (gametes). Depending on the gender, it occurs in the testis in males and ovaries in females. For females, the sex cells are formed before their birth, and thus have a fixed number of gametes. For males, sperm can be produced from puberty onwards.
