Problem:OPTIONS:
- excitation engine

- ventilation engine
- carnot engine

Answer the following question given this paragraph: An ideal engine, the most efficient theoretically possible, is called a Carnot Engine. Its efficiency is given by the following formula, where the temperatures are, respectively, the temperature of the exhaust environment and the temperature of the heat input, in Kelvins. In a Carnot engine heat is input and exhausted in isothermal cycles, and the efficiency is . In all real engines heat is lost to the environment, thus the ideal efficiency is never even close to being obtained. Q: What is the name of the the most efficient possible engine? A:
****
A: carnot engine

Answer the following question given this paragraph: 39.2 Gas Exchange across Respiratory Surfaces The lungs can hold a large volume of air, but they are not usually filled to maximal capacity. Lung volume measurements include tidal volume, expiratory reserve volume, inspiratory reserve volume, and residual volume. The sum of these equals the total lung capacity. Gas movement into or out of the lungs is dependent on the pressure of the gas. Air is a mixture of gases; therefore, the partial pressure of each gas can be calculated to determine how the gas will flow in the lung. The difference between the partial pressure of the gas in the air drives oxygen into the tissues and carbon dioxide out of the body. Q: Tidal volume, expiratory reserve volume, inspiratory reserve volume, and residual volume are all types of what kind of measurement? A:
OPTIONS:
- respiratory volume
- emitted volume
- breathing volume
- lung volume
lung volume

Answer the following question given this paragraph: All crocodilians have, like humans, teeth set in bony sockets. But unlike mammals, they replace their teeth throughout life. Crocodiles and gharials (large crocodilians with longer jaws) have salivary glands on their tongue, which are used to remove salt from their bodies. This helps with life in a saltwater environment. Crocodilians are often seen lying with their mouths open, a behavior called gaping . One of its functions is probably to cool them down. Q: Lying with their mouths open, a behavior called gaping, probably serves what function for crocodiles? A:
OPTIONS:
- sleeping
- digesting
- eating
- cooling down

Answer: cooling down

Question: Answer the following question given this paragraph: Visible light is the only light that humans can see. Different wavelengths of visible light appear as different colors. Radio waves have the longest wavelengths. They also have the least amount of energy. Infrared light has wavelengths too long for humans to see, but we can feel them as heat. The atmosphere absorbs the infrared light. Ultraviolet (UV) light is in wavelengths too short for humans to see. The most energetic UV light is harmful to life. The atmosphere absorbs most of this UV light from the Sun. Gamma rays have the highest energy and they are the most damaging rays. Fortunately, gamma rays don't penetrate Earth's atmosphere. Q: What is the only light that humans can see? A:
OPTIONS:
- dark light
- distinct light
- bright light
- visible light
Answer: visible light

input with options: Answer the following question given this paragraph: Ionic compounds consist of oppositely charged ions that are held together by ionic bonds. The opposite charges cancel out so ionic compounds have a net neutral charge. Ionic compounds form when metals transfer valence electrons to nonmetals. Q: What kind of charge do iconic compounds have? A:
OPTIONS:
- net negative charge
- net positive charge
- white neutral charge
- net neutral charge
output: net neutral charge

Problem: OPTIONS:
- stars
- plants
- fungi
- animals
Q: Answer the following question given this paragraph: Q: Nearly all apicomplexans are parasites of what? A:
Answer:
animals
