Fossil record in this case
The structure that is labelled C would be a protein, a specific type of protein that helps in regulating the transport of substances in and out of the cell.
"Net force" simply means the sum of all forces. The "unless acted upon by a net force" version is more correct. For example, as you stand or sit still, the earth pushes you up with a force equal and opposite to the force with which gravity pulls you down. The net force, or total force, is zero, so you do not move.
The top layers are the youngest and the farther you go down, the older they get. I’ll put it in exact order in a minute.
Answer:
Through nuclear pores.
Explanation:
The nucleus of a eukaryotic cell is double membrane-enclosed organelles which enclose the genetic material of the cell.
Although the nucleus contains the nuclear membrane but the molecules are exported and imported into the cells through small pores known as the nuclear pores.
The mRNA is synthesised through the process of the transcription is exported out of the nucleus through these nuclear pores.
Thus, the nuclear pore is correct.
