472. Find the incorrect one [General Knowledge for APSET Examination-2013]

Correct Answer: Correct answer is: (C) Bel is used to measure atmospheric pressure.

Exam Relevance: APSET, GRE, GATE, GMAT

Difficulty: Easy

Concept notes: The bel is a unit used to measure sound intensity or power ratios, not atmospheric pressure.

Common Mistakes: Students may confuse the bel with other units of measurement, such as the bar or Pascal, which are used to measure atmospheric pressure.

Explanations: The bel is a logarithmic unit used to measure the ratio of two power levels. It is commonly used in acoustics and electronics to measure sound intensity or power ratios. Atmospheric pressure, on the other hand, is typically measured in units such as Pascal (Pa), bar, or millibar (mb). Therefore, the statement that the bel is used to measure atmospheric pressure is incorrect.

Option Analysis:

Option A: Hertz is the correct unit for measuring frequency.
Option B: Kelvin is the correct unit for measuring temperature.
Option C: Bel is not used to measure atmospheric pressure; it is used to measure sound intensity or power ratios.
Option D: Ohm is the correct unit for measuring electrical resistance.

Common Mistakes: Students might mistakenly think vegetables can be grown in other locations like on a bridge or in a barn, which do not provide the necessary conditions for vegetable growth.

Explanations: Vegetables require soil, sunlight, and water to grow. Fields provide these essential conditions, making them the ideal location for vegetable cultivation. Other options like bridges, rivers, and barns do not offer the necessary environment for vegetable growth.

475. The various organsof mouth parts used for biting, sucking, chewing etc of insects, though differ externally and in functions, are built on the same basic plan and it is termed [General Knowledge for IBPS Clerk Examination-1984]

Correct Answer: Correct answer is: (B) Homology.

Exam Relevance: IBPS Clerk, UPSC, GRE, MCAT

Difficulty: Moderate

Concept notes: Homology refers to structures in different species that have a common evolutionary origin, even if they may have different functions.

Common Mistakes: Students may confuse homology with analogy, which refers to structures that have similar functions but different evolutionary origins.

Explanations: The various mouth parts of insects, such as those used for biting, sucking, and chewing, are built on the same basic plan despite their different functions. This shared basic structure indicates a common evolutionary origin, which is the definition of homology.

Option Analysis:

Option A: Analogy refers to structures with similar functions but different evolutionary origins, which does not apply here.
Option B: Homology refers to structures with a common evolutionary origin, which fits the description of the insect mouth parts.
Option C: Parallel evolution refers to similar structures evolving independently in different lineages, which is not the case here.
Option D: Isolation refers to the separation of populations, which is not relevant to the structure of mouth parts.

Mnemonic: Homology: "Same origin, different jobs."

476. "The 'RTI Act, 2005' stipulates that a Public Authority should transfer an RTI application or a part thereof to another Public Authority if the application or a part of it pertains to information" [SSC GD Examination-2001]

Option Analysis:

Option A: This is a valid condition under the RTI Act, 2005.
Option B: This is also a valid condition under the RTI Act, 2005.
Option C: Both conditions (A) and (B) are valid under the RTI Act, 2005.
Option D: This is incorrect as both conditions (A) and (B) are valid.

Mnemonic: RTI Transfer: "Hold & Function" (H&F)

477. For a body floating in water, the apparent weight is equal to [General Knowledge for Staff Selection Commission Examination-2003]

Correct Answer: Correct answer is: (C) Weight of the body minus weight of the liquid.

Exam Relevance: Staff Selection Commission Examination, Civil Services Examination, Engineering Entrance Exams

Difficulty: Moderate

Concept notes: The apparent weight of a floating body is the difference between its actual weight and the buoyant force exerted by the liquid.

Common Mistakes: Students often confuse the apparent weight with the actual weight or the buoyant force alone.

Explanations: When a body floats in water, it experiences an upward buoyant force equal to the weight of the liquid displaced by the body. The apparent weight is the net force acting on the body, which is the actual weight of the body minus the buoyant force. The buoyant force is equivalent to the weight of the liquid displaced, hence the apparent weight is the weight of the body minus the weight of the liquid displaced.

Option Analysis:

Option A: The actual weight of the body does not account for the buoyant force, which is incorrect for a floating body.
Option B: The apparent weight is not zero; it is the difference between the actual weight and the buoyant force.
Option C: This is correct as the apparent weight is the weight of the body minus the weight of the liquid displaced.
Option D: Adding the upward thrust to the weight of the body would not give the apparent weight, which is the difference between the weight and the buoyant force.

478. The drug produced through bio-technology for cancer treatment is [General Knowledge for Sikkim PSC Examination-1990]

Correct Answer: Correct answer is: (A) Interferon.

Exam Relevance: Sikkim PSC, UPSC, SSC, Banking Exams

Difficulty: Moderate

Concept notes: Interferon is a type of protein that is produced by the body's immune system to fight viral infections and cancer. It can also be produced through biotechnology for therapeutic use.

Common Mistakes: Students may confuse interferon with other biotechnology-derived drugs like insulin, which is used to treat diabetes, or human growth hormone (H.G.H.), which is used to treat growth disorders.

Explanations: Interferon is a drug that can be produced through biotechnology and is used in the treatment of cancer. It works by stimulating the immune system to attack cancer cells. Insulin, H.G.H., and T.S.H. are not primarily used for cancer treatment.

Option Analysis:

Option A: Interferon is a drug produced through biotechnology and used for cancer treatment.
Option B: Insulin is a hormone used to treat diabetes, not cancer.
Option C: H.G.H. (Human Growth Hormone) is used to treat growth disorders, not cancer.
Option D: T.S.H. (Thyroid-Stimulating Hormone) is related to thyroid function and not cancer treatment.

Correct Answer: Correct answer is: (B) Nirvana.

Exam Relevance: UPSC, IAS, Civil Services

Difficulty: Moderate

Common Mistakes: Students may confuse Nirvana with Moksha, which is a similar concept in Hinduism.

Explanations: In Buddhism, the ultimate goal is to achieve Nirvana, which is the state of liberation from the cycle of rebirth and suffering. This state is achieved through the cessation of desire and attachment, leading to enlightenment and the end of the cycle of reincarnation.

Option Analysis:

Option A: Moksha is the equivalent concept in Hinduism, not Buddhism.
Option B: Nirvana is the correct term for the ultimate goal in Buddhism.
Option C: Understanding is a part of the path but not the ultimate goal.
Option D: Reincarnation is the cycle that Buddhists aim to end, not the goal itself.
