The right answer is ribosomal RNA.
<span>William E. Balch and Al </span>in the publication in 1977 about the phylogenetic tree based on the ribosomal RNA gene sequences of the organisms studied, a tree in which prokaryotes were divided into two distinct domains, that of bacteria and that of archaea.
And we know that eucaryotes and procaryotes have different ribosomal RNA, for example, the ribosomes of the procaryotes are 70s (Svedberg), and the ribosomes of the eucaryotes are 80s.
Answer: cell membrane
such as water, micro-organism
physical process
simple diffusion, osmosis and filtration
such as potasssium permaganate in water,urea a liver waste diffuses from the body and the kidney help in filtering it out
physiological processs
active transport, phagocytosis and pinocytosis
such as soduim-potassium pump, exocytosis
Explanation: transportation in and out of cell is done in different ways listed above but a barrier to this movement is the cell membrane which is an outer covering of the cell. it protect the cell and only some materials can penetrate the cell membrane e.g micro-organism, water e.t.c. the various physical and physiological processes are the various ways substance cna be liquid, solid or gas are transported within or outside the cell e.g food
Answer:
I know A is Nucleus, but I am not sure about the others
Answer:
Inside the nucleus lies the blueprint that dictates everything a cell will do and all of the products it will make. This information is stored within DNA. The nucleus sends “commands” to the cell via molecular messengers that translate the information from DNA.
