Answer the following question given this paragraph: Dietary proteins are broken down during digestion to provide the amino acids needed for protein synthesis. Any extra proteins in the diet not needed for this purpose are used for energy or stored as fat. One gram of proteins provides 4 Calories of energy. Q: One gram of proteins provides how many calories of energy? Choices: - eight - zero - two - four A:
four

A: kin selection
Question: Answer the following question given this paragraph: 41.4 | Nitrogenous Wastes By the end of this section, you will be able to: Compare and contrast the way in which aquatic animals and terrestrial animals can eliminate toxic ammonia from their systems Compare the major byproduct of ammonia metabolism in vertebrate animals to that of birds, insects, and reptiles Of the four major macromolecules in biological systems, both proteins and nucleic acids contain nitrogen. During the catabolism, or breakdown, of nitrogen-containing macromolecules, carbon, hydrogen, and oxygen are extracted and stored in the form of carbohydrates and fats. Excess nitrogen is excreted from the body. Nitrogenous wastes tend to form toxic ammonia, which raises the pH of body fluids. The formation of ammonia itself requires energy in the form of ATP and large quantities of water to dilute it out of a biological system. Animals that live in aquatic environments tend to release ammonia into the water. Animals that excrete ammonia are said to be ammonotelic. Terrestrial organisms have evolved other mechanisms to excrete nitrogenous wastes. The animals must detoxify ammonia by converting it into a relatively nontoxic form such as urea or uric acid. Mammals, including humans, produce urea, whereas reptiles and many terrestrial. Q: What term is used to describe animals that excrete ammonia? Choices: - spirogyra - ammonstand - xerophyte - ammonotelic A:
Answer: ammonotelic
*Question*
Answer the following question given this paragraph: Recall that the only required ingredients needed for photosynthesis are sunlight, carbon dioxide (CO 2 ), and water (H 2 O). From these simple inorganic ingredients, photosynthetic organisms produce the carbohydrate glucose (C 6 H 12 O 6 ), and other complex organic compounds. Essentially, these producers are changing the energy from the sunlight into a usable form of energy. They are also making the oxygen that we breathe. Oxygen is a waste product of photosynthesis. Q: For photosynthesis to begin, the inputs required are sunlight, water, and what? Choices: - phosphorus dioxide - methane - sulfur dioxide - carbon dioxide A:
**Answer**
carbon dioxide

Answer the following question given this paragraph: Gamma rays are the most energetic of all electromagnetic waves. They can pass through most materials, including bones and teeth. Nonetheless, even these waves are useful. For example, they can be used to treat cancer. A medical device sends gamma rays the site of the cancer, and the rays destroy the cancerous cells. If you want to learn more about gamma rays, watch the video at the URL below. Q: What are the most energetic of all electromagnetic waves, which can be used to treat cancer? Choices: - ultraviolet - infrared - X-ray - gamma rays A:
(Answer)
gamma rays
