Answer;
The answer is A. Gametes
Explanation;
Both sperm cells and egg cells are gametes that are both products of meiosis type of cell division. Which means they are haploid,n, they have have number of chromosomes as the normal cells. Gametes are haploid , meaning that they ave just one complete set of chromosomes. Diploid cells are the body cells other than the gametes that have two copies of each chromosome.

Explanation:
Answer:
D. marks transformation of nitrogen (N₂) from the atmosphere to ammonium (NH₄ plus) by bacteria.
Explanation:
The nitrogen cycle is a biogeochemical cycle which involves transformation of atmoshperic nitrogen into many chemical forms including nitrite (NO2), nitrates (NO3) and ammonium (NH4).
The process of nitrogen cycle starts with the process of nitrogen fixation. In this process several nitrogen fixation bacteria such as cyno bacteria converts the atmospheric nitrogen into ammonium (NH4) in the soil. The resultant ammonium (NH4) can be directly used by plants or transform into nitrites or nitrates through nitrification process.
Hence, the correct option is D.
