What are three factors that can change a gene pool without leading to adaption?

Well if I'm reading into this right you kinda have the answer in the picture mutation, migration, genetic drift, and natural selection are all examples of microevolution which are very small changes over a large amount of time that don't really lead to adaptation

Both of them have a nucleus, golgi apparatus, cell membrane, smooth and rough endoplasmic reticulum, lysosome, and ribosomes.
