Answer:
Meiosis
Meiosis is the process involved in the production of pollen or male sex cells in an angiosperm flower.
Explanation:
<span>In human beings the "master switch" that determines whether an individual will become a male is the SRY gene, which is found on the Y chromosome. The sex-determining region Y protein produced from this gene acts as a transcription factor, meaning it attaches to specific regions of DNA and helps control the activity of particular genes.</span>
Answer:
active; prokaryotes
Explanation:
Active transport can be defined as the movement of molecules across cell membranes against a concentration gradient, i.e., from a region of low concentration to a region of high concentration. Group translocation is a specialized type of active transport observed in prokaryotic cells. In group translocation, the transported substance is chemically modified during its movement, thereby the cell membrane becomes impermeable to this substance once it is within the cell. In bacteria, the phosphotransferase system is a type of group translocation that uses phosphoenolpyruvate (PEP) as a source of energy to transport sugar molecules into the cell.
