Answer:
Diffusion is the movement of molecules from a region of higher concentration to a region of lower concentration down the concentration gradient.
Answer:
D-DNA molecule
Explanation:
The process of copying the sequence of DNA nucleotide sequences to the mRNA is called Transcriptions. It is the first stage in gene expression for protein synthesis, and<u> it involves the unwinding of the DNA double strands molecules by enzyme</u><u> </u>DNA Helicase into two free strands,(by melting the hydrogen bonds between organic bases), a process initiated by the binding of enzymes RNA Polymerase to the promoter sites on the DNA template; the alignment of the mRNA nucleotides on the single DNA template strands in 3'-5 direction; the formation of hydrogen bonds between the organic bases of the template DNA and that of the messenger RNA single strands,( and phosphodiesterbonds within RNA nucleotide ), to form DNA-RNA complex.
The copying is done in complimentary anti parallel fashion;5'-3' prime. direction.
The hydrogen bonds, between the bases DNA-RNA complexes breaks,and the releases the mRNA which exists through the nuclear pores.Thus this <u>leads to copying of the the coded messages as seqeunce of DNA , from the DNA to the mRNA for gene expressions.</u>
Shorter mRNA will be found in the ribosomes when comparisons are made
with the mRNA from inside the nucleus.
<h3>Ribosomes</h3>
Ribosomes are organelles which acts as sites for protein synthesis. This is
where the mRNA gets converted into polypeptides which have longer
chains.
Ribosomes have a shorter mRNA in the ribosome which becomes longer in
the nucleus after synthesis of larger polypeptides. this is the reason why
there is a variation in the size of the mRNA found in the ribosome and
nucleus.

Answer:
The respiratory system and the circulatory.
Explanation:
The respiratory system brings in the oxygen and the circulatory system brings all of the oxygen through out the body.
