🚨🚨 Incorrect keys of UHS

THE UHS PORTAL WILL BE OPEN FOR COMPLAINING REGARDING THE ISSUES IN THE KEY
The following were the mistakes in the key of UHS. Kindly report them:

CODE A
MCQs:

7 - SEVEN:
The answer selected by UHS is the chemical formula of chlorophyll b. However, it is not mentioned in the statement whether it is chlorophyll a or b.
(BIO Ptb, page 210, Class 11)

11 - ELEVEN:
The general formula of monosaccharides contains at least 3 to 7 carbon atoms. It should be Cn(H2O)n.
(Page 20, Bio Ptb, Class 11)

22 - TWENTY-TWO:
ADH is produced by the hypothalamus. This was not given in the options.
(Page 72, Bio Ptb, Class 12)

68 - SIXTY-EIGHT:
Chromosomes were first observed by Walther Flemming. This is out of the syllabus.
(Page 122, Bio Ptb, Class 12)

185 - ONE HUNDRED AND EIGHTY-FIVE:
Both A and B are correct. The comma used in a series or bulk of adjectives before "and" is called the Oxford comma. It is an optional comma used as per the preference of the writer.
(Wren and Martin, or any other Grammar source)

SZABMU OUT OF SYLLABUS / WRONG MCQs

Biology:

1. Which bones form the eye socket? (Eye socket is not in our course, only bones are included.)


2. The concentration of K+ ions inside the cell is 30 times greater than outside the neuron membrane, but the only options given were 10, 15, 20, and 25 times. The options were wrong.


3. Crossing over occurs in the pachytene stage, which is out of course (FTB).


4. Coxal bones form _____ joint. This is not written in the book.


5. Drosophila shows overdominance, which is not from Federal Biology. Only complete dominance, co-dominance, and incomplete dominance are explained.


6. Brown color is shown by which type of carbohydrates when treated with iodine? (Only red with glycogen and blue with iodine are mentioned in Federal Biology.)


7. Photorespiration is excluded from the MDCAT course.


8. Crossing over occurs in which phase? (Chapter 21 Ptb is not included in the syllabus.)


9. Which bones are involved in eye sockets? (The skeleton is not included. All options were correct.)


10. Cyanobacteria (Only size, shape, and structure of bacteria are included.)


11. Anaerobic bacteria (Only size, shape, and structure of bacteria are included.)


12. Turner’s syndrome (Chapter 20 Ptb is not included.)


13. The percentage of CO2 in anaerobic respiration is not mentioned anywhere.


14. Cyanide binds to the active site (multiple correct answers, whereas FTB states cyanide binds to the allosteric site).


15. Gallstones are composed of (not in FTB).


16. NADH transfers electrons to cytochrome-Q via _______. (Options included 4 types of phosphorylation, none of which were mentioned in FTB.)


17. The nature of surfactant in respiratory distress syndrome (not in FTB).


18. Lungs are enveloped in a double membrane called the pleura (not mentioned in FTB).


19. SA node conduction lasts 0.04 seconds. (Not in options. 0.15 seconds was given, which is the total time for conduction from the SA node to the AV node and from the AV node to the bundle of His.)


20. Kingdom Plantae (not included in the syllabus).


21. The percentage of energy produced in anaerobic respiration (the correct answer is 2%, but it’s not mentioned in FTB).

Chemistry:

1. Stability order of Group 4 elements: Sn+2, Pb+2, Ge+2 (Not included in the syllabus; only Groups 1 & 2 are included).


2. Partial pressure of gas (not included in the syllabus).


3. If the rate constant is for the reaction at 200°C, what will be the rate constant at 250°C? (Ea not given, and can't be calculated without a calculator.)


4. Find molarity (not included in the syllabus).


5. Find the concentration of ions if pH = 4 (Acid-bases not included in the syllabus, only buffers are).




---

Physics:

1. The best condition for maximum work in physics (statements are unclear; in expansion, work done is maximum in the isobaric process; in contraction, it is maximum in the adiabatic process, but total heat is transformed into work in the isothermal process).
