1. Which of the following is a consequence of bone marrow failure?

Correct answer: B

Rationale: The corrected question focuses on the consequence of bone marrow failure, which is pancytopenia. Bone marrow failure results in decreased production of red blood cells, white blood cells, and platelets, leading to pancytopenia. This condition manifests as fatigue, weakness, increased infection susceptibility, and bleeding tendencies. Paraplegia, seizures, and pathologic fractures are not typical outcomes of bone marrow failure. Paraplegia is associated with spinal cord injury, seizures with neurological disorders, and pathologic fractures with conditions like osteoporosis or bone tumors.

2. What is the formula to calculate gravitational potential energy near the Earth's surface?

Correct answer: D

Rationale: The correct formula to calculate gravitational potential energy near the Earth's surface is Potential Energy = Mass × Acceleration due to gravity × Height. This formula considers the mass of the object, the specific acceleration due to gravity near the Earth's surface (approximately 9.81 m/s^2), and the vertical distance from the reference point. Choice A is incorrect as it does not include height in the formula. Choice B is incorrect as it involves force instead of acceleration due to gravity. Choice C is incorrect as it multiplies mass, height, and gravity, missing the actual acceleration due to gravity term.

3. What is the general formula for an alkene?

Correct answer: B

Rationale: The general formula for an alkene is \(C_nH_{2n}\), indicating the presence of a double bond between carbon atoms.

4. Which type of isomerism arises due to differences in the arrangement of atoms around a double bond?

Correct answer: C

Rationale: Cis-trans isomerism, also known as geometric isomerism, arises due to differences in the arrangement of atoms around a double bond. In cis isomers, similar groups are on the same side of the double bond, while in trans isomers, similar groups are on opposite sides of the double bond. This type of isomerism is a subset of stereoisomerism, which includes all isomers that have the same connectivity but differ in spatial arrangement. Chain isomerism involves differences in the carbon chain arrangement, functional group isomerism involves different functional groups, and stereoisomerism is a broader category that encompasses isomers with the same connectivity but different spatial arrangement.

5. Which of the following organs is responsible for producing digestive enzymes?

Correct answer: B

Rationale: The correct answer is the Pancreas. The pancreas is an organ that produces digestive enzymes to aid in the breakdown of food in the small intestine. These enzymes play a crucial role in the digestion and absorption of nutrients from the food we eat. The liver is responsible for producing bile, not digestive enzymes. The gallbladder stores and concentrates bile produced by the liver, which aids in the digestion of fats. The esophagus is a muscular tube that helps in the movement of food from the mouth to the stomach and does not produce digestive enzymes.
