<h2>Answer:</h2>

The primary purpose of the cell membrane is to preserve the cell from its surroundings

<h2>Explanation:</h2>

The primary purpose of the cell membrane is to preserve the cell from its surroundings.The cell membrane is also named selectively permeable membrane for the single reason being it is particular in nature. Furthermore, in diffusion and osmosis, only specific molecules transfer through the cell membrane. Diffusion helps the entrance of important molecules like water, carbon, and oxygen.

The cell membrane is selectively permeable to ions and organic molecules and controls the movement of substances in and out of cells. The basic function of the cell membrane is to protect the cell from its surroundings. It consists of the phospholipid bilayer with embedded proteins.

HELP!!!!

svetlana [45]

Answer:

Transcription

Explanation:

This occurs in three steps itself: initiation, elongation, and termination

Initiation (beginning)

- RNA polymers bind to a promoter on a gene

- DNA then unwinds to be "read" by an enzyme

- DNA now ready to make mRNA strand

Elongation (Second step)

- nucleotides are added to mRNA strand

- mRNA molecule is built after RNA polymers reads the DNA that unwound

- adenine (A) in DNA connects to a uracil (U) of RNA while connected to each other

Termination (End)

- RNA will cross a stop sequence in the gene (termination)

- mRNA done and disconnects or detaches from DNA

Hope this helps!
