1. Beta waves, associated with alertness and focused attention, typically fall within the range of:

Correct answer: D

Rationale: Beta waves are neural oscillations in the brain that are associated with alertness, concentration, and active thinking. They typically fall within the frequency range of 13-30 Hz. This range is indicative of a person being awake, alert, and engaged in cognitive tasks requiring focus. Lower frequency ranges like 0.5-4 Hz (Delta waves) are associated with deep sleep and unconsciousness, while higher ranges like 8-13 Hz (Alpha waves) are linked to a relaxed and meditative state. Therefore, option D (13-30 Hz) is the correct range for beta waves, reflecting the brain's heightened activity during periods of attentiveness and concentration.

2. Which element makes up the majority of the Earth's atmosphere?

Correct answer: A

Rationale: Nitrogen is the most abundant gas in the Earth's atmosphere, crucial for plant life and maintaining the planet's temperature balance.

3. Describe the ethical considerations surrounding the potential use of CRISPR-Cas9 technology in humans.

Correct answer: B

Rationale: CRISPR-Cas9's ability to precisely edit germline cells raises ethical dilemmas about modifying the human gene pool. This includes concerns about eugenics, unintended consequences, and the long-term impact on future generations.

4. What is the scientific name for the kneecap?

Correct answer: A

Rationale: The patella, commonly known as the kneecap, is a small, flat, triangular bone that sits at the front of the knee joint. It protects the joint from impact and helps to transmit force from the quadriceps muscle to the tibia (shinbone).

5. You need to repaint a cylindrical water tank with a diameter of 2 meters and a height of 3 meters. Assuming one can of paint covers 10 sq m, how many cans do you need (consider only the exterior surface)?

Correct answer: C

Rationale: Calculate the surface area of the cylinder and divide by the coverage area per can.

6. The largest level of ecological organization is a:

Correct answer: D

Rationale: Rationale: A) Population: A population consists of individuals of the same species living in the same area. It is a smaller level of ecological organization compared to a biome. B) Community: A community consists of populations of different species living and interacting in the same area. It is a larger level of organization than a population but smaller than an ecosystem or biome. C) Ecosystem: An ecosystem includes all living organisms (biotic factors) and their physical environment (abiotic factors) interacting in a particular area. It is a larger level of organization than a community but smaller than a biome. D) Biome: A biome is the largest level of ecological organization and encompasses a large geographic area characterized by a specific climate, vegetation, and animal life. Biomes can be found on multiple continents and are defined by similar abiotic and biotic factors.
