Problem: OPTIONS:
- nervous
- immune
- digestive
- respiratory
Q: Answer the following question given this paragraph: Weeks 1624 Once the respiratory bronchioles form, further development includes extensive vascularization, or the development of the blood vessels, as well as the formation of alveolar ducts and alveolar precursors. At about week 19, the respiratory bronchioles have formed. In addition, cells lining the respiratory structures begin to differentiate to form type I and type II pneumocytes. Once type II cells have differentiated, they begin to secrete small amounts of pulmonary surfactant. Around week 20, fetal breathing movements may begin. Q: Alveolar ducts and broncioles are developing parts of what organ system? A:
Answer: respiratory

Problem:OPTIONS:
- stabilizes
- fluctuates rapidly
- increases
- decreases

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:
****
A: decreases

Answer the following question given this paragraph: Archaeans are now known to live just about everywhere on Earth. They are important decomposers. Many live in close relationships with other organisms. They are generally harmless and often beneficial. Q: Which important decomposers are known to live just about anywhere on earth? A:
OPTIONS:
- protazoas
- viruses
- sporozoans
- archeans
archeans

Answer the following question given this paragraph: When plants and other organisms die, decomposers break down their remains. In the process, they release nitrogen in the form of ammonium ions. This process is called ammonification. Nitrifying bacteria change the ammonium ions into nitrites and nitrates. Some of the nitrates are used by plants. The process of converting ammonium ions to nitrites or nitrates is called nitrification. Still other bacteria, called denitrifying bacteria, convert some of the nitrates in soil back into nitrogen gas in a process called denitrification. The process is the opposite of nitrogen fixation. Denitrification returns nitrogen gas back to the atmosphere, where it can continue the nitrogen cycle. Q: What process is the opposite of nitrogen fixation? A:
OPTIONS:
- digestion
- respiration
- percolation
- denitrification

Answer: denitrification

Question: 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:
OPTIONS:
- digestion
- respiration
- excretion of waste
- to transport
Answer: to transport

input: OPTIONS:
- proteins
- fat
- vitamins
- carbohydrates Now, answer this question: Answer the following question given this paragraph: Producers such as plants or algae use carbon dioxide in the air to make food. The organisms combine carbon dioxide with water to make sugar. They store the sugar as starch. Both sugar and starch are carbohydrates. Consumers get carbon when they eat producers or other consumers. Q: Sugar and starch are examples of what type of nutrient? A:
A:
output:
carbohydrates
