Answer:
The appearance of a plasma membrane that surrounded the genetic material allowed the products of the genetic material to be kept close and the external environment of this protocell was different from the external environment.
Step-by-step explanation:
The cell membrane, which constitutes the outer boundary of the cell. Through it, all the exchanges of matter and energy with the environment are carried out. The "Theory of Biological Evolution by Natural Selection" explains, based on natural causes, how the diversity of the living world originated - including human beings - and why many organisms are so similar to each other, with small and large variants, and others apparently so different. All cells have a cell membrane and genetic material. All living things reproduce, copying their genetic material and transmitting it to their descendants.
