Question 1 of 5
What is a common cause of a tsunami?
Correct Answer: A
Rationale: Earthquakes are a common cause of tsunamis. When an earthquake occurs under the ocean, it can displace a large volume of water, triggering a series of powerful waves known as a tsunami. Sunspot activity, lightning strikes, and flooding do not directly cause tsunamis. Therefore, the correct answer is earthquakes, as they are the primary geological event that leads to the formation of tsunamis.

Question 2 of 5
Why is nitrogen gas an extremely stable molecule?
Correct Answer: C
Rationale: The correct answer is C - triple covalent bonds. Nitrogen gas (N2) is composed of two nitrogen atoms held together by a triple covalent bond. This bond is very strong and requires a significant amount of energy to break, making nitrogen gas a stable molecule. Triple covalent bonds involve the sharing of three pairs of electrons, resulting in a very stable configuration. Resonance bonds, ionic bonds, and hydrogen bonds are not present in the structure of nitrogen gas, hence they do not contribute to its stability.
Question 3 of 5
In experimental design, which group can be measured against the experimental group as a standard of comparison?
Correct Answer: A
Rationale: The control group is a critical component in experimental design as it serves as a reference point for comparison with the experimental group. The control group does not receive the experimental treatment but is subjected to all other conditions. By comparing the outcomes of the experimental group with those of the control group, researchers can evaluate the impact and efficacy of the experimental treatment.
Question 4 of 5
Lithium has an atomic number of 3 and a mass number of 7. What is the number of protons in a lithium atom?
Correct Answer: D
Rationale: The number of protons in an atom is equal to its atomic number. In this case, lithium has an atomic number of 3, so it contains 3 protons. The mass number (7) includes both protons and neutrons, with the difference between the mass number and atomic number representing the number of neutrons. Therefore, the correct answer is 3 protons in a lithium atom.

Which of the following structures is correctly associated with its immune function?
Correct Answer: C
Rationale: The spleen is responsible for filtering blood and removing germs, making option C the correct association of structure and immune function.
