Answer:
Black color absorb more light that other color.
Explanation:
Photosynthesis is the process in which leaves absorb solar energy and use it to convert CO2 and H2O into chemical energy called glucose(food).
As photosynthesis is dependent on the sunlight energy therefore it has been suggested to scientists that they should genetically engineer a plant to have black leaves as black color absorbs more sunlight than any other color. Black color absorb all the wavelength of sunlight and it does not reflect any.
So more light absorbance capability of black color should be the reason behind this idea.
Answer: anti-Mullerian hormone (AMH)
Explanation:
Testes is a reproductive organ present in males which produces hormone s including androgen and testosterone.
Testes also produces a specific hormone called anti-Mullerian hormone (AMH) or Mullerian inhibiting factor that is responsible for sexual differentiation. Anti-Mullerian hormone (AMH is produced by the Sertoli cells in male fetuses which signals to prevent the development of fallopian tubes, Mullerian ducts, and uterus.
Hence, anti-Mullerian hormone (AMH) prevent development of uterus and fallopian tubes in male fetuses.
