Physics

1. What happens to the speed of a sound wave when it travels from air to water?

Correct answer: A

Rationale: Sound waves travel faster in denser mediums like water compared to air due to stronger interactions between particles.

2. Half-life refers to the characteristic time it takes for:

Correct answer: D

Rationale: The correct answer is D: An isotope to decay by half of its initial quantity. The half-life of a substance is the time it takes for half of the initial quantity of radioactive atoms to decay. This is a characteristic property of each radioactive isotope and is used to determine the rate of decay of a substance. Option A is incorrect because radioactive intensity does not completely disappear in half-life, it only decreases by half. Options B and C are unrelated to the concept of half-life and do not accurately describe its definition.

3. Which molecule allows for the selective passage of materials into and out of the cell?

Correct answer: D

Rationale: The correct answer is D, the phospholipid bilayer. The phospholipid bilayer is the main component of the cell membrane, which acts as a selective barrier allowing certain molecules to pass through while blocking others. Its structure consists of hydrophilic heads facing outward towards the aqueous environments inside and outside the cell, while the hydrophobic tails face inward creating a semi-permeable barrier. DNA (A) is the genetic material of the cell and is located within the nucleus, not involved in material passage. Proteins (B) and carbohydrates (C) are important components of the cell membrane and play various roles, but they do not directly control the selective passage of materials in and out of the cell.

4. What literary device is used in the phrase "the lion's roar thundered across the savanna"?

Correct answer: A

Rationale: Option A compares the roar to thunder using "like" or "as," making it a simile.

5. What is the term for the chemical reaction that involves the loss of electrons?

Correct answer: b

Rationale: Oxidation is the chemical reaction that involves the loss of electrons. The other choices describe different types of reactions.

6. Which of the following is a weak acid commonly found in citrus fruits?

Correct answer: c

Rationale: Citric acid is a weak acid commonly found in citrus fruits. The other choices are strong acids.
