TLDR;

This video provides solutions and explanations for questions 51-75 from the 2023 B.Ed. Science (CU-QP06) PYQ exam. The questions cover a range of topics including physics, biology, computer science, and general knowledge. Key concepts discussed include static electricity, Ohm's law, X-linked recessive diseases, assisted reproductive technologies, computer science basics, biotechnology, material properties, and more.

Assertion-reason questions require understanding the relationship between statements.
Matching questions test knowledge across different domains.
Some questions are based on Class 10th level science.

Question 51: Assertion and Reason on Static Electricity [0:26]

The question presents an assertion about a comb attracting paper after being run through dry hair and a reason involving static charge development due to friction and charge transfer. Both the assertion and the reason are correct. The static charge developed on the comb due to rubbing is precisely why it attracts the bits of paper. This phenomenon is known as charging by rubbing, where charge is transferred between the comb and hair, resulting in opposite charges and attraction.

Question 52: Ohm's Law Limitations [1:45]

This question asks about the conditions under which Ohm's Law fails. Ohm's Law (V = IR) fails when the V-I characteristic is non-linear, when the V-I characteristic depends on the sign of V (positive or negative), and when the V-I characteristic is not unique. Therefore, the correct answer includes all these conditions.

Question 53: X-Linked Recessive Diseases [3:07]

The question requires identifying X-linked recessive diseases from a list. Hemophilia and color blindness are X-linked recessive disorders, while sickle cell anemia, phenylketonuria, and thalassemia are autosomal disorders. Therefore, the correct answer is the option that includes Hemophilia and color blindness.

Question 54: Assisted Reproductive Technology [3:54]

The question asks to identify which of the listed options is NOT an assisted reproductive technology. Zygote Intrafallopian Transfer (ZIFT), Gamete Intrafallopian Transfer (GIFT), and Intra Uterine Insemination (IUI) are all assisted reproductive technologies. Intra Uterine Devices (IUDs) are contraceptive devices used for population control, not reproductive assistance.

Question 55: Matching Computer Science Terms [4:28]

This question involves matching computer science terms with their definitions. A blog is an online journal, a webpage is a document using HTTP, a protocol is a set of rules, and a website is a location on a net server. Matching these terms correctly leads to the correct answer.

Question 56: Matching Biotechnology Terms [5:26]

The question requires matching biotechnology terms. Peptides of mature insulin are related to the removal of the C chain. Proteins encoded by cry genes are controlled by Bacillus thuringiensis. Vectors used to transfer nematodes are Agrobacterium, and the organism where the insecticidal gene is located is Bacillus thuringiensis, used against cotton bollworms.

Question 57: True Statements About Computer Systems [6:19]

The question asks to identify the statement that is NOT true about computer systems. A computer system consists of data, software, hardware, communications, and people. Computer systems can be divided into subsystems and can vary in size. However, the statement that a computer system is not an effective way to provide solutions to problems is false.

Question 58: Dimensionless Quantities [7:16]

The question asks which of the listed quantities has no units and no dimensions. Refractive index is a ratio and therefore dimensionless, while Planck's constant, gravitational constant, and density all have dimensions and units.

Question 59: Job Responsibilities in Hotel Management [7:39]

The question describes Mr. X's responsibilities in a hotel, which include organizing and supervising the front office in the absence of the front office manager. This indicates that Mr. X is likely an Assistant Manager, as they are responsible for the manager's duties when the manager is unavailable.

Question 60: Oxidation State Calculation [8:28]

The question asks for the oxidation state of K in K2O. By setting up the equation 2x - 2 = 0, where x is the oxidation state of K, we find that x = +1.

Question 61: Nutritional Care Process [8:56]

The question requires arranging the activities of nutritional care processing during illness in the correct order. The correct order is: assess nutritional status, diagnose nutritional status, plan and prioritize, and then evaluate the nutritional care outcome.

Question 62: Fabric Defects [9:49]

The question asks which of the following is NOT a fabric defect arising from weaving faults. Slub is a yarn defect, not a weaving fault.

Question 63: Casparian Strips [10:28]

The question asks where Casparian strips are found. Casparian strips are found in the dicotyledonous root. These strips, made of suberin, regulate water and mineral flow in the root.

Question 64: Genetic Information Transfer [11:21]

The question asks about the process of copying genetic information from DNA to RNA. This process is termed transcription, as part of the central dogma of molecular biology.

Question 65: Composition of Nichrome [11:59]

The question asks about the composition of Nichrome. Nichrome is an alloy made of nickel, iron, and chromium.

Question 66: Factors Enabling Multiple Rice Crops [12:30]

The question asks which agroeconomic feature enables South Indian states to raise three crops of rice annually. Better irrigation facilities make this possible because rice requires a lot of water.

Question 67: Diamagnetic Materials [13:32]

The question asks which of the following is NOT a diamagnetic material. Platinum is a paramagnetic material, while diamond, gold, silver, and glass are diamagnetic. Diamagnetic materials are weakly repelled by a magnetic field.

Question 68: HTML Full Form [14:45]

The question asks for the full form of HTML. HTML stands for Hyper Text Markup Language.

Question 69: Statements on Quality Management and Thread Count [14:56]

The question presents two statements: one about problem-solving with the purpose of getting a zero defect, and another about thread count. The first statement incorrectly identifies zero defect as quality control (it is quality management), and the second statement incorrectly defines thread count as weight (it is the number of threads in a fabric). Both statements are false.

Question 70: Matching Craft Types with States [15:38]

The question requires matching craft types with their states of origin. Shola craft is from Odisha, Channapatna dolls are from Karnataka, Warli painting is from Maharashtra, and bamboo craft is from Assam.

Question 71: Incorrectly Matched Protein Pair [16:40]

The question asks which of the following is NOT a correct match pair. Lysosome is an enzyme, not a structural protein.

Question 72: Effect of Earth's Rotation on Gravity [17:15]

The question asks what would happen to the acceleration due to gravity if the Earth stopped rotating. The acceleration due to gravity would be equal everywhere.

Question 73: Symbol for Flammable Materials [17:46]

The question asks which symbol letter is used for the identification of highly flammable dangers. The symbol "F" is used for flammable materials.

Question 74: Stages of Guest Cycle [18:28]

The question requires arranging the stages of a guest cycle in the appropriate sequence. The correct sequence is pre-arrival, arrival, occupancy, and departure.
