Answer: In females, most of gametogenesis occurs during embryonic development. Primordial germ cells migrate into the ovaries at week 4 of development and differentiate into oogonia (46,2N).
Explanation:
Adhesion can be defined as the process of attachment of a substance on the surface another. This attachment can be because of the physical or chemical linkage. The physical adhesion can be reversed using enough force.
Among the given options, the water droplets sticking to a window represents the process of adhesion. The water droplets are attached to the surface of the glass. The water forming a large drop is example of cohesion. The water evaporating from leaf is an example of evaporation, and the water falling from the sky is an example of condensation.
Hence, the correct answer is option (A) - water droplets sticking to a window.
Answer: C. Scientific observations show that microscopic organisms living in the deep ocean are not made up of cells
Explanation: The cellular theory says that cells are the structural and functional basic unit of life, that all living organisms are made up of cells and that cells came from other cells. This theory should be modified if there's scientific observations that challenge the postulates: living organisms that were not made up of cells can't have cells as functional and structural units, for example.
Synthesis and transport of polypeptides.
The transcription process is the formation of mRNA from the DNA. Hence the product of the transcription process is mRNA. The translation process is the formation of protein molecule from the mRNA. Hence the product of the translation process is the proteins.
