That is correct. Any animal that produces milk is a mammal. That is the key characteristic that defines Class Mammalia.
The first major difference between prokaryote and eukaryote gene expression is the location. Due to lack of compartments (nucleus) prokaryotic gene expression (both transcription and translation) occurs within the cytoplasm (genetic material is located within the cytoplasm). So, transcription and translation in prokaryote occurs simultaneously. Gene expression in eukaryote occurs in both the nucleus (transcription) and cytoplasm (translation).
The steps of regulation of gene expression are also dissimilar, in prokaryotic cell, transcription is mostly the main point of regulation (eukaryote have transcription, post-transcription, translation, and post-translation regulation together with epigenetic regulation).
The nitrogen cycle could no exist without bactria. bacteria that lived inside the ground, catch the nitrogen that has been fixed and covert it into nitrate.
Photosynthesis, because the equation is using light energy and producing oxygen, like a plant, which use photosynthesis to make food.
