Genes are located on chromosomes and these chromosomes are passed into the gametes in sexual reproduction. If two genes are closely linked, it is likely that their positions on a chromosome are close together. This is why they are likely to be sent into the same gamete of the parent and inherited by the offspring.
Facilitatad diffusion needs the help of Transport proteins.
Carbohydrates, polymers, proteins, and nucleic acids.
These are, well, large organic molecules that are synthesized from multiple identical subunits, as questioned above.
Hope this helps!
