Answer the following question given this paragraph: Photosynthetic bacteria use the energy of the sun to make their own food. In the presence of sunlight, carbon dioxide and water are turned into glucose and oxygen. The glucose is then turned into usable energy. Glucose is like the "food" for the bacteria. An example of photosynthetic bacteria is cyanobacteria, as seen in the opening image. Q: What is glucose used for the bacteria? A:

OPTIONS:
- reproduction
- fuel
- energy
- food

Answer: food

Problem: OPTIONS:
- digestion
- respiration
- excretion of waste
- to transport
Q: Answer the following question given this paragraph: The main function of blood is transport. Blood in arteries carries oxygen and nutrients to all the body's cells. Blood in veins carries carbon dioxide and other wastes away from cells to be excreted. Blood also transports the chemical messengers called hormones to cells throughout the body where they are needed to regulate body functions. Blood has several other functions as well. For example, blood:. Q: What is the main function of blood? A:
Answer: to transport

Problem:OPTIONS:
- fruits
- legumes
- algae
- mushrooms

Answer the following question given this paragraph: Mushrooms are fungi that are eaten by people all over the globe. Q: Which fungi eaten by people all over the world? A:
****
A: mushrooms

Answer the following question given this paragraph: The mouth also begins the process of mechanical digestion. Sharp teeth in the front of the mouth cut or tear food when you bite into it (see Figure below ). Broad teeth in the back of the mouth grind food when you chew. Food is easier to chew because it is moistened by saliva from the salivary glands. The tongue helps mix the food with saliva and also helps you swallow. After you swallow, the chewed food passes into the pharynx. Q: Teeth in the back of the mouth are used for what? A:
OPTIONS:
- swallowing food
- tearing food
- cutting food
- grinding food
grinding food

Answer the following question given this paragraph: The Gaia hypothesis states that the biosphere is its own living organism. The hypothesis suggests that the Earth is self-regulating and tends to achieve a stable state, known as homeostasis . For example the composition of our atmosphere stays fairly consistent, providing the ideal conditions for life. When carbon dioxide levels increase in the atmosphere, plants grow more quickly. As their growth continues, they remove more carbon dioxide from the atmosphere. In this way, the amount of carbon dioxide stays fairly constant without human intervention. Q: What is the hypothesis that states that the biosphere is its own living organism? A:
OPTIONS:
- Big Bang theory
- Geiger theory
- Pascal's hypothesis
- gaia hypothesis

Answer: gaia hypothesis

input with options: Answer the following question given this paragraph: The product of a wave's wavelength () and its frequency (), , is the speed of the wave. Thus, for electromagnetic radiation in a vacuum: c = 2.998 10 8 ms 1 = Wavelength and frequency are inversely proportional: As the wavelength increases, the frequency decreases. The inverse proportionality is illustrated in Figure 6.3. This figure also shows the electromagnetic spectrum, the range of all types of electromagnetic radiation. Each of the various colors of visible light has specific frequencies and wavelengths associated with them, and you can see that visible light makes up only a small portion of the electromagnetic spectrum. Because the technologies developed to work in various parts of the electromagnetic spectrum are different, for reasons of convenience and historical legacies, different units are typically used for different parts of the spectrum. For example, radio waves are usually specified as frequencies (typically in units of MHz), while the visible region is usually specified in wavelengths (typically in units of nm or angstroms). Q: The product of a wave's wavelength and its frequency is what? A:
OPTIONS:
- trough
- velocity
- amplitude
- speed
output:
speed
