Answer:
B. Primary spermatocytes
Explanation:
The germ cell line is a group of cells found inside the seminiferous tubules. This germ cells undergo mitosis (creating spermatogonia) to have a steady supply of cells that will divide by meiosis to produce gametes. When spermatogonia divide by meiosis at the end of meiosis I the newly created cells are known as primary spermatocytes.
Platelets would help the blood clot, therefore preventing blood loss. White Blood Cells would help protect against infection. So, I believe the answer would be platelets & white blood cells.
The answer is the equilibrium concentrations or pressures of each species that occurs in the equilibrium expression, or enough information to determine them. These values are substitued into the equilibrium expression and the value of the equilibrium constant is then calculated.
