1. What is the involuntary process of emptying the bladder called?

Correct answer: B

Rationale: Micturition, also known as urination or voiding, is the involuntary process of emptying the bladder. During micturition, the bladder muscle contracts, and the sphincter muscles relax, allowing urine to be expelled from the body. Filtration is the process of separating solids from liquids in the body, not related to emptying the bladder. Reabsorption involves absorbing substances back into the bloodstream, not related to emptying the bladder. Excretion is the process of eliminating waste products from the body, not specifically the process of emptying the bladder.

2. What type of intermolecular force is responsible for the high surface tension of water?

Correct answer: A

Rationale: The high surface tension of water is primarily due to the strong hydrogen bonding between water molecules. Hydrogen bonding is a specific type of intermolecular force that occurs between a hydrogen atom covalently bonded to a highly electronegative atom, like oxygen in water, and another electronegative atom nearby. This unique interaction results in a strong attraction between water molecules at the surface, leading to the cohesive forces responsible for the high surface tension of water. Choices B, C, and D are incorrect because London dispersion forces, ionic bonding, and metallic bonding do not account for the high surface tension observed in water. London dispersion forces are relatively weaker intermolecular forces, while ionic and metallic bonding are types of intramolecular forces that do not directly contribute to the surface tension of water.

3. What is the unit of measurement for force in the International System of Units (SI)?

Correct answer: A

Rationale: The unit of measurement for force in the International System of Units (SI) is the Newton (N). One Newton is defined as the force required to accelerate a mass of one kilogram at a rate of one meter per second squared. Therefore, the correct answer is Newton (N). The other choices are incorrect because: B) Kilogram (kg) is a unit of mass, not force; C) Joule (J) is a unit of energy; D) Meter per second squared (m/s²) is a unit of acceleration, not force.

4. What is the relationship between work and kinetic energy?

Correct answer: A

Rationale: Work is defined as the transfer of energy that results in an object's displacement. When work is done on an object, it gains kinetic energy. This means that work is the cause of kinetic energy, as the energy transferred through work leads to the object's motion, which is represented by kinetic energy. Therefore, choice A is correct. Choice B is incorrect because kinetic energy is the result of work, not the other way around. Choice C is incorrect as work and kinetic energy are not equivalent but rather interconnected. Choice D is incorrect as work and kinetic energy are not independent; work leads to changes in kinetic energy.

5. Bile, a digestive juice, is produced by which organ?

Correct answer: B

Rationale: Bile is a digestive juice produced by the liver. It is stored in the gallbladder and released into the small intestine to aid in the digestion and absorption of fats. The stomach (Choice A) produces gastric juices, not bile. The pancreas (Choice C) produces digestive enzymes and bicarbonate but not bile. The small intestine (Choice D) is where bile is released to aid in digestion but is not the organ that produces bile.
