This carbon dioxide in process of respiration diffuse out of the tissues in form of molecular carbon dioxide and join with water forming carbonic acid ...
In lungs again carbon dioxide is separated and released out of the body...
On his visit to the Galapagos Islands, Charles Darwin discovered several species of finches that varied from island to island, which helped him to develop his theory of natural selection.
Distal Convoluted Tubule and Collecting Duct are parts of the nephron does ADH act on to regulate water reabsorption. ADH acts throughs G-protein coupled receptor in order to increase transcription and the insertion of Aquaporin–2 channels for the apical membrane of the CD and DCT cells. Therefore, the permeability of CD and DCT cells to the water increases.
A Distal Convoluted Tubule (DCT) is a short nephron segment, a portion of kidney nephron between Henle or macula densa and the collecting tubule loop. It plays an important role in regulating extracellular fluid volume and electrolyte homeostasis. In DCT, Sodium absorption occurs, which is mediated by the hormone aldosterone.

Answer:
<h3>A) Enzymes are highly specific protein catalysts</h3>
Explanation:
- Enzymes are highly specific protein catalysts i.e. it react with only that substrate for which it has been made.
- Enzymes have an active site by which it binds to substrate at that specific site.
- Enzymes lowers the activation energy required for completion of a chemical reaction. As a result rate of the reaction increases.
- Enzymes never participate in a chemical reaction rather they are obtained back in its original form on the completion of the reaction.
