Answer:
The correct answer will be- direction, the RNA polymerase will add nucloetides.
Explanation:
RNA polymer is an enzyme which adds nucleotide complementary to the DNA template strand. The RNA polymerase enzymes attach to the DNA strand at the promoter region which with the help of other factors will start transcription and will form RNA molecule.
The RNA strands are formed with polarity in 5’ to 3’ direction as the RNA polymerase adds the new nucleotide at to the 3' end of the strand. Thus, the RNA polymerase will bind to the strand of the DNA which runs in 3' to 5' direction which is known as the template strand or antisense strand.
Thus, direction, the RNA polymerase will add nucleotides is the correct answer.
Answer:
muscles
ribs
lungs
bronchioles
alveoli
diffuses
leaves
exchange
Explanation:
Your diaphragm, and <u>muscles</u> between your <u>ribs</u>, make air move in and out of your <u>lungs</u>. It travels through the trachea, bronchi, and <u>bronchioles </u>to <u>alveoli</u>. In the alveoli, oxygen <u>diffuses</u> into the blood and carbon dioxide<u> leaves</u>. This is gas <u>exchange</u>.
<em>Air enters the lungs and leaves it as a result of the relaxation and contraction of the diaphragm and the muscles between the ribs. When both the muscles and the diaphragm relax, air enters from the trachea and travels through the bronchi and the bronchioles to the alveoli, where the oxygen in the air diffuses into the blood and carbon dioxide diffuse in the opposite direction. The entire process is known as gas exchange.</em>
An endergonic reaction, like photosynthesis, refers to a reaction, which needs the energy to be driven. The activation energy for the reaction is usually greater in comparison to the entire energy of the exergonic reaction. The endergonic reactions are non-spontaneous.
In the given case, in order to accomplish the process, the coupling of the endergonic reaction, that is, thermodynamically unstable reaction with an exergonic, that is, the thermodynamically stable reaction is done so that the entire free-energy change of the coupled reactions becomes negative.
