Answer: transfer of energy.
Explanation:
Gravitational is only attracted and electromagnetic is both atrractive and repulsive since it depends what you are talking about
If you turned a frog egg upside down, you would expect it to reorient relative to gravity because the dense yolk granules concentrated in the vegetal hemisphere of the egg respond to gravity.
The frog egg is very large as compared to the normal egg cell. It is unevenly distributed with a top dark colored pole called animal pole and a light yolky pole called a vegetal pole.
The vegetal pole is concentrated with the yolk that is present for providing the nourishment to the growing embryo. The animal pole is the one from where the sperm enters and the development of embryo take place.
As the vegetal pole is denser as compared to animal pole so it will respond to the gravity and reorient along the direction of gravity.

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.
