Zielflug [23.3K]

Answer:

<u>Option- </u> Passive transport.

  • The movement or transport of medium across an area or membrane on the basis of there concentration is termed to be the main mechanism for providing all the vital resources for the cell and tissue survival inside the body.                                                

Explanation:

  • Osmosis involves the movement of water molecules across a cell membrane. Diffusion involves the movement of substances other than water across a cell membrane. In both of these processes, substances move from an area of high concentration to an area of low concentration. Thus, both diffusion and osmosis are forms of <u>Passive transport.</u>

Protein Folding Notes
Sindrei [870]

What does nitrogen fixation accomplish?
alexgriva [62]

Answer:

A. It allows plants to use nitrogen to grow.

Explanation:

However, plants can't directly use nitrogen to grow. The bacteria need to convert atmospheric nitrogen ( N2 gas) into a form that plants can use.

Nitrogen fixation is a symbiotic relationship between plants and microorganisms of nitrogen fixers, which in the process of symbiosis perform the binding of nitrogen, which enters the earth from the air (atmosphere).

It is a reduction process of converting the gaseous form of nitrogen from the air into the ammonia form that is available to plants.

jenyasd209 [6]

Answer:

<h2>Codon </h2>

Explanation:

The sequence of DNA is transcribed into mRNA, containing the sequence  for protein synthesis, protein is synthesized according to the codons in mRNA.  This sequence of nucleotide on DNA/ RNA is divided into a series of three nucleotide units, and one unit of three nucleotide is  known as codons.

There are overall 64 codons, 61 codons out of 64 codons, codes for overall 20  amino acids, and the remaining three  are stop codons.

These there codon do not code for any amino acid.

And these 61 codons, they  code for total 20 amino acids. So one amino acid can be coded by one or more than one codons.
