Exchange of oxygen and carbon dioxide in the lungs occurs between the __________ and the alveoli.A. capillaries
B. bronchi
C. arteries
D. veins

Answers

Answer: Option A

Explanation:

The exchange of the oxygen and carbon dioxide takes place in the lungs. The oxygen from the lungs are exchanged by the carbon dioxide between the alveoli and capillaries.

The oxygen from the lungs are carried away to various cells of the body and the carbon dioxide from the body cells are carried to the lungs for the process of exchange of gases.
capillaries.

Exchange of oxygen and carbon dioxide in the lungs occurs between the capillaries and the alveoli.

How can two molecules with the same chemical formula react differently?

Answers

The molecules that have the different structural formula but the same chemical formula are known as isomers. Isomers explain the relationship between molecular arrangements that, although differing in chemical or physical properties. Chemical reactions in which one isomer is transformed into different are called isomerizations. A rapid equilibrium that cannot be easily isolated involved by isomerization is known as tautomerization.
"Different substances sometimes have the same chemical formula, such as glucose and fructose, but they have different components so they act differently."

Write a note on RNA polymerase

Answers

Answer:

Ther RNA polymerases (abbreviated as RNAPs or RNA pols), represent a group of conserved enzymes that synthesize RNA from DNA templates

Explanation:

These enzymes are used to synthesize different RNA species such as, amon others, messenger RNA (mRNA), transference RNA (tRNA), noncoding RNAs (ncRNAs), etc. During the gene transcription, the RNA pol is used to produce a mRNA molecule that subsequently is translated into protein

Answer: By definition, RNA polymerase or ribonucleic acid polymerase is a multi-subnunit enzyme that catalyze the process of transcription where an RNA polymer is synthesized from a DNA template.

Explanation:

RNA polymerase are highly conserved in evolution among eukaryotes, bacteria, archea and some viruses. Bacreria and archea has a single RNA. RNA polymerase are considered as molecular motors because of their stepwise movement on DNA. They are also central to biology information flow since they catalyzed templated polymerization reaction.
