<h3><u>Answer;</u></h3>
C) P and Q have similar binding properties
<h3><u>Explanation;</u></h3>
- <u><em>Enzymes are biological catalysts that speeds up chemical reactions. Substrates are substances that are acted on by an enzyme to form a product.</em></u>
- <u><em>An enzyme catalyzed reaction occurs when the substrate binds to the active site of an enzyme to form and enzyme-substrate complex. </em></u>
- <em><u>Substrate P and Q are structurally similar which means they are in a position of binding and fitting in the active site of an enzyme. The strong structural similarity means that the binding properties of these two different substrates may be similar. </u></em>
- <em><u>Formation of similar products or results when acted upon by an enzyme mean they are similar in terms of their binding properties, and thus the production of similar product.</u></em>
Some plants, like cacti, contain water.
Vestigal organs are organs that, as we evolve, the organs loose their purpose and have no function anymore. The appendix is a vestigal organ

Answer:
The correct answer will be option-A.
Explanation:
ADH or anti-diuretic hormone is a chemical messenger produced by the hypothalamus in response to the water level in the blood, maintain blood pressure.
ADH is released in response to the osmolarity of the blood that is a low amount of water which is perceived by the osmorecpetors in neurons. The low level of water leads to the production of ADH from neurons which binds to the ADH receptors in the collecting tubules of the kidneys.
They allow insertion of aquaporins-2 in the membrane which allow re-absorption of the water to maintain the water level of the body.
Thus, option-A is the correct answer.
