Answer the following question given this paragraph: 29.4 Reptiles The amniotes are distinguished from amphibians by the presence of a terrestrially adapted egg protected by amniotic membranes. The amniotes include reptiles, birds, and mammals. The early amniotes diverged into two main lines soon after the first amniotes arose. The initial split was into synapsids (mammals) and sauropsids. Sauropsids can be further divided into anapsids (turtles) and diapsids (birds and reptiles). Reptiles are tetrapods either having four limbs or descending from such. Limbless reptiles (snakes) are classified as tetrapods, as they are descended from four-limbed organisms. One of the key adaptations that permitted reptiles to live on land was the development of scaly skin containing the protein keratin, which prevented water loss from the skin. Reptilia includes four living clades: Crocodilia (crocodiles and alligators), Sphenodontia (tuataras), Squamata (lizards and snakes), and Testudines (turtles). Q: The amniotes are distinguished from amphibians by the presence of a terrestrially adapted egg protected by what? Choices: - hard shell - yolk - albumen - amniotic membranes A:
amniotic membranes
Answer the following question given this paragraph: The key to how a refrigerator or other cooling system works is the refrigerant. A refrigerant is a substance with a low boiling point that changes between liquid and gaseous states as it passes through the refrigerator. Q: What do you call the substance in a cooling system that has a low boiling point and changes between liquid and gaseous states? Choices: - byproduct - emission - coolant - refrigerant A:
refrigerant
Q: Answer the following question given this paragraph: Triglycerides in the diet are digested in the small intestine. Since lipids are not water-soluble, they are emulsified with the help of bile acids, which are produced by the liver and stored in the gall bladder. Bile acids are cholesterol-derived steroids that also contain a water-soluble component. The nonpolar region of these acids can interact with triglycerides, and the water-soluble portion allows the entire complex to dissolve in the aqueous environment within the body. Q: Where are bile acids, needed to emulsify lipids, stored in the body? Choices: - liver - womb - cerebellum - gallbladder A:
A: gallbladder
Question: Answer the following question given this paragraph: Excess water is absorbed from food waste in the large intestine before it passes out of the body through the anus as feces. Trillions of helpful bacteria also live in the large intestine. They carry out important roles, such as making vitamins. Q: What is absorbed from food waste in the large intestine before it passes out of the body as feces? Choices: - distilled water - dependent water - inactive water - excess water A:
Answer: excess water

Answer the following question given this paragraph: A seamount is a volcanic mountain on the ocean floor. Seamounts that rise above the water surface are known as islands. There are many seamounts dotting the seafloor. Q: What are seamounts that rise above the water surface called? Choices: - sandbars - coasts - reefs - islands A:
**Answer**
islands

Answer the following question given this paragraph: Earth is a giant magnet with north and south magnetic poles and a magnetic field called the magnetosphere. Evidence in rocks shows that Earth's magnetic poles switched positions hundreds of times in the past. Scientists think that Earth's magnetic field is caused by the movement of charged particles through molten metals in the outer core. Q: The magnet field of earth is called what? Choices: - atmosphere - troposphere - ionosphere - magnetosphere A:
(Answer)
magnetosphere
