Answer:
Hemophilia is a x-linked recessive inherited bleeding disorder. in this disease blood does not clot properly due to the decreased level of blood clotting factor VIII (8) or factor IX (9).
In x-linked recessive condition, the disease is transmitted from father (affected male) to his daughter and mother (affected female) to her son and skip of generation getting affected is also occurs.
- there will be 50% chance of her (S.R.) each son to be affected with hemophilia.
Explanation:
Hemophilia is caused due to mutation of one gene which is responsible for the making of proteins of blood coagulation factor viii or ix. the affected person bleeds continuously from any injury and that can cause serious issues.
here,
grandfather of s.r is affected (xₐy) and grandmother is normal (xx) will produce
↓
s.r's mother who is a carrier (xₐx) [as xₐy and xx will produce 100% carrier xₐx daughter]
↓
s.r's mother is a carrier (xₐx) but her father is normal (xy) will produce,
↓
s.r who has 50% chance of being carrier (xₐx) and 50% chance of being normal (xx) [as she is the only child] and she has a normal (xy) partner, they will give,
↓
- if s.r is a carrier (xₐx) then one of her son will be affected (xₐy) [as xₐx and xy =xₐy]
- if s.r is normal (xx) then her son will be normal (xy) [as xx and xy will give xy]
here,<u> 50% chance of her son to be affected with hemophilia</u> [as S.R of being affected is more considerable].

<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>

Answer:
C.Both Gram positive and Gram negative cells would appear purple.
Explanation:
Gram staining is a technique used to differentiate bacteria to two main groups based on their difference in cell wall components.
Crystal violet, decolorizer(ethanol) and a counter stain are used.
Gram positive bacteria have a thicker peptidoglycan layer hence they will retain the crystal Violet stain even after decolorization. They will stain purple
Gram negative will stain pink due to losing the initial stain and taking up the counter stain after decolorization.
Therefore, if water is used instead of ethanol. Both bacteria will retain crystal violet stain in their cell wall.
