Question 8922

Purine bases (adenine and guanine) are catabolized in humans to which end product, whose excessive accumulation in blood and tissues causes gout?

Urea
Uric acid✔️
Creatinine
Ammonia

Correct Answer Logic:

Humans lack uricase (present in most other mammals), so purine catabolism terminates at uric acid, which is relatively insoluble and can crystallize in joints (gouty arthritis) or the urinary tract (uric acid stones) when produced in excess or excreted inadequately.

Agriculture Economics QUESTION #11866

Question 8924

Total Fixed Costs ($TFC$) are best described as costs that:

Vary directly with output
Do not change with the level of output in the short run✔️
Only occur in the long run

Quantitative Reasoning QUESTION #8030

Question 8925

The theory of cosmic evolution holds that the universe, having originated in a state of simplicity and _______, has since transformed _______ into great variety.

homogeneity .. differentiated✔️
equilibrium .. modulated
contrast .. metamorphosed
proportion .. accelerated

Correct Answer Logic:

The sentence describes a universe moving from unity/sameness to diversity. Homogeneity...differentiated is the best fit: the universe began as uniform (homogeneous) and then became differentiated (divided into varied forms). 'Equilibrium...modulated' doesn't capture the idea of increasing variety as strongly.

Civil / Architecture QUESTION #2366

Question 8926

In the context of Green Building design, the Overall Thermal Transfer Value (OTTV) is a metric used to evaluate:

The amount of heat generated by building occupants and equipment per unit floor area
The total heat gain through the building envelope (walls, roofs, and fenestration) per unit area of the building facade, used to set energy performance benchmarks✔️
The coefficient of performance (COP) of the HVAC system
The total solar radiation incident on the building roof per year

Correct Answer Logic:

OTTV (Overall Thermal Transfer Value, in W/m²) is an energy code metric used in tropical and subtropical regions (including ECBC in Pakistan/India) that quantifies the total heat gain through the building envelope per unit external wall area. It accounts for conduction through opaque walls, solar radiation through windows (WWR, SHGC), and conductive heat through glazing. A lower OTTV indicates a more thermally efficient building envelope.

Education QUESTION #7590

Question 8927

Which assessment focuses on measuring what students can actually do rather than simply recall facts?

Performance-based assessment✔️
Objective test
Oral test
Short-answer test

Correct Answer Logic:

Performance-based assessment requires students to demonstrate skills through actual tasks or activities, showing application rather than just factual recall.

Physics QUESTION #7233

Question 8928

The dimensional formula of magnetic field $B$ is:

$M^1L^2T^{-3}A^{-1}$
$M^1L^{-1}T^{-2}A^{-1}$
$M^1L^0T^{-2}A^{-1}$✔️
$M^1L^1T^{-2}A^{-1}$

Correct Answer Logic:

From Lorentz force: $F = qvB$

$[B] = \dfrac{[F]}{[q][v]} = \dfrac{MLT^{-2}}{AT \cdot LT^{-1}} = \dfrac{MLT^{-2}}{AL} = MT^{-2}A^{-1} = M^1L^0T^{-2}A^{-1}$

Accounting & Finance QUESTION #6132

Question 8929

Y Limited purchased a motor van with these costs: Purchase price $50,000; Delivery $4,500; Engine upgrade $6,000; 2-year maintenance contract $4,000; Annual licence fee $1,200. Depreciation: 20% straight-line. What are the total expenses in the statement of profit or loss?

$14,340
$15,300✔️
$17,300
$20,100

Correct Answer Logic:

Option B ($15,300) is correct.

Capital expenditure: $50,000 + $4,500 + $6,000 = $60,500

Depreciation = $60,500 × 20% = $12,100

Revenue expenditure: Maintenance (year 1 only) $4,000 ÷ 2 = $2,000 + Licence $1,200 = $3,200

Total expenses = $12,100 + $3,200 = $15,300

Biology Zoology Botany QUESTION #1353

Question 8931

All of the following statements regarding 'lung ventilation' and 'gas exchange' in birds are TRUE EXCEPT:

Abdominal and thoracic air sacs are compressed by body muscles to move air through the respiratory system
Gas exchange occurs in blind-ending sacs called alveoli✔️
Two respiratory cycles are required to move a volume of air through the respiratory system
None of these

Correct Answer Logic:

Statement (B) is FALSE for birds. In birds, gas exchange does NOT occur in blind-ending alveoli (as in mammals) but in microscopic tubes called parabronchi, where air flows unidirectionally. This allows continuous, highly efficient gas exchange in both inhalation and exhalation. Statements (A) and (C) are true — air sacs act as bellows and two breath cycles are needed to move air through the entire system.

Question 8932

Which of the following BEST describes computer PERIPHERALS?

Internal components soldered directly onto the motherboard
External devices connected to a computer that add functionality, such as a mouse, keyboard, and monitor✔️
Software programs installed on the computer's hard drive
The set of instructions stored in the BIOS chip

Correct Answer Logic:

Peripherals are the external devices which we connect to our computer that add functionality. Common examples include a mouse, keyboard, monitor, printer, and external hard drive. They are 'peripheral' because they are external to the main computing unit.

MBBS QUESTION #10236

Question 8934

Rigor mortis, the stiffening of muscles after death, is best explained physiologically by:

Continued ATP-dependent cross-bridge cycling after death
Depletion of cellular ATP, which is required to detach myosin heads from actin, leaving cross-bridges locked in place✔️
Excessive calcium reuptake into an intact sarcoplasmic reticulum
Loss of troponin function alone, with normal ATP levels

Correct Answer Logic:

ATP is required not for cross-bridge formation but for detaching myosin from actin, allowing the cycle to reset. After death, ATP stores are depleted and calcium leaks uncontrolled into the sarcoplasm, allowing cross-bridges to form but never releasing — producing the sustained, irreversible-until-decomposition stiffness of rigor mortis.

Question 8940

What is the meaning of Al Hadi mentioned in the Holy Quran?

The Light
The Eternal
The Rich
The Guide✔️

Correct Answer Logic:

Al-Hadi is one of the 99 Names of Allah meaning 'The Guide'. It appears in the Quran multiple times, emphasizing that Allah alone guides people to the right path. Those whom Allah guides, none can misguide, and those whom He allows to go astray, none can guide. This name reflects Allah's attribute of providing guidance through revelation, prophets, and natural signs. Muslims invoke this name when seeking guidance in life's matters.
