A reproductive cell must differ from other normal body cells. The reproductive cell must because it will soon fuse with another reproductive cell to form a new individual

I'm not 100% sure what the exact answer is to this, because lots of things could be said about what gametes need to do for reproduction.

I suppose since it says that it's combining with another cell, it's hinting at the fact that reproductive cells are haploid.

If this is multiple choice I would choose the choice that has to do with gametes being haploid.

micro/nanoscale topography surface exhibits many prominent properties and is extensively employed in biomedical device, microfluidic device and energy device fabrication. additionally, the clinical applications of biomaterials can be largely expanded with of nanostructured surfaces.
