<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>
That Trait (Hitchhiker's thumb) may be recessive in both the parents but when they transmitted their genes to their offspring, it became dominant in that 'cause of two similar genes (Homozygous Condition).

Patent ductus arteriosus occurs when the normal fetal circulation conduit between the pulmonary artery and the aorta fails to close and results in increased pulmonary blood flow. The clinical manifestations of patent ductus arteriosus include; Murmur; wide and bounding pulse pressure, Asymptomatic Heart failure.
