input with options: Answer the following question given this paragraph: AM radio waves are used to carry commercial radio signals in the frequency range from 540 to 1600 kHz. The abbreviation AM stands for amplitude modulation, which is the method for placing information on these waves. (See Figure 24.12. ) A carrier wave having the basic frequency of the radio station, say 1530 kHz, is varied or modulated in amplitude by an audio signal. The resulting wave has a constant frequency, but a varying amplitude. A radio receiver tuned to have the same resonant frequency as the carrier wave can pick up the signal, while rejecting the many other frequencies impinging on its antenna. The receiver's circuitry is designed to respond to variations in amplitude of the carrier wave to replicate the original audio signal. That audio signal is amplified to drive a speaker or perhaps to be recorded. Q: What type of radio waves exist in the 540 to 1600 khz frequency range? A:
OPTIONS:
- microwaves
- sound waves
- fm radio waves
- am radio waves
output: am radio waves

Q: Answer the following question given this paragraph: In chemosynthesis, organisms break down chemicals to make food energy. Q: What is the process by which organisms break down chemicals to make food energy? A:

OPTIONS:
- excretion
- gametogenesis
- electrolysis
- chemosynthesis

A: chemosynthesis

input: OPTIONS:
- chemical bloom
- caustic bloom
- agricultural bloom
- algal bloom Now, answer this question: Answer the following question given this paragraph: When fertilizer ends up in bodies of water, the added nutrients cause excessive growth of algae. This is called an algal bloom. You can see one in Figure below . The algae out-compete other water organisms. They may make the water unfit for human consumption or recreation. Q: When fertilizer ends up in bodies of water, the added nutrients cause excessive growth referred to as what, which can render the water unfit for human consumption or recreation? A:
A:
output: algal bloom

Answer the following question given this paragraph: Excretion is the process of removing wastes and excess water from the body. It is one of the major ways the body maintains homeostasis. Although the kidneys are the main organs of excretion, several other organs also excrete wastes. They include the large intestine, liver, skin, and lungs. All of these organs of excretion, along with the kidneys, make up the excretory system . The roles of the excretory organs other than the kidney are summarized below:. Q: What is the process of removing wastes and excess water from the body called? A:

OPTIONS:
- inspiration
- ingestion
- diffusion
- excretion

Answer: excretion

Problem: OPTIONS:
- stabilizes
- fluctuates rapidly
- increases
- decreases
Q: Answer the following question given this paragraph: Gas solubility decreases as the temperature increases. Q: What happens to gas solubility as the temperature increases? A:
Answer: decreases

Answer the following question given this paragraph: As you can see in this NASA photo, Earth is tiny compared with the massive sun. The sun's gravity is relatively strong because the force of gravity between two objects is directly proportional to their masses. Gravity between the sun and Earth pulls Earth toward the sun, but Earth never falls into the sun. Instead, it constantly revolves around the sun, making one complete revolution every 365 days. Q: The sun's gravity is relatively strong because the force of gravity between two objects is directly proportional to their what? A:

OPTIONS:
- tissues
- Liquids
- rocks
- masses

Answer:
masses
