Read this paragraph and choose the correct option from the provided answers: Carbonated beverages contain carbon dioxide gas that is dissolved in solution. Do you think a carbonated beverage is a mixture or a pure substance? Explain. Choices: - phosphorus dioxide - carbon monoxide - hydrogen peroxide - carbon dioxide A:
carbon dioxide

(Question)
Q: The electron released during beta decay is not an orbital electron but an electron whose origin was where? Read this paragraph and choose the correct option from the provided answers: The symbol represents an electron whose charge corresponds to and since it has no nucleons, . It must be carefully noted that the electron released during beta decay is NOT an orbital electron but an electron whose origin was in the nucleus. The process has one neutron becoming one proton and one electron and the electron being emitted as a beta particle. Since a neutron has been lost AND a proton has been gained, the mass number does not change. The atomic number, however, has increased one due to the gain of a proton. Therefore, as a result of beta decay, the daughter product will have the same mass number as the parent and an atomic number one greater than the parent. Choices: - outside the nucleus - connected to the nucleus - orbiting the nucleus - in the nucleus A:
(Answer)
in the nucleus

Ques: Q: This bodily defense function attacks pathogens and includes inflammatory response and phagocytosis? Read this paragraph and choose the correct option from the provided answers: The second line of defense attacks pathogens that manage to enter the body. It includes the inflammatory response and phagocytosis by nonspecific leukocytes. Choices: - first line of defense - third line of defense - vomitting - second line of defense A:
Ans: second line of defense

Q: What type of stratified deposit is formed where lakes are covered by ice in the winter? Read this paragraph and choose the correct option from the provided answers: Several types of stratified deposits form in glacial regions but are not formed directly by the ice. Varves form where lakes are covered by ice in the winter. Dark, fine-grained clays sink to the bottom of the lake in winter. Melting ice in the spring brings running water that deposits lighter colored sands. Each alternating dark/light layer represents one year of deposits. Choices: - telomeres - glacier - tangles - varves A:
(A).
varves

Ques:Q: What kind of bonds are forces of attraction between positive metal ions and the valence electrons that are constantly moving around them? Read this paragraph and choose the correct option from the provided answers: Metallic bonds are forces of attraction between positive metal ions and the valence electrons that are constantly moving around them (see the Figure below ). The valence electrons include their own and those of other, nearby ions of the same metal. The valence electrons of metals move freely in this way because metals have relatively low electronegativity, or attraction to electrons. The positive metal ions form a lattice-like structure held together by all the metallic bonds. For an animated version of metallic bonding, go to this URL:. Choices: - neutron bonds - liquid bonds - ionized bonds - metallic bonds A:

Ans:metallic bonds

Q: Lipids are available to the body from how many sources? Read this paragraph and choose the correct option from the provided answers: 24.3 Lipid Metabolism Lipids are available to the body from three sources. They can be ingested in the diet, stored in the adipose tissue of the body, or synthesized in the liver. Fats ingested in the diet are digested in the small intestine. The triglycerides are broken down into monoglycerides and free fatty acids, then imported across the intestinal mucosa. Once across, the triglycerides are resynthesized and transported to the liver or adipose tissue. Fatty acids are oxidized through fatty acid or -oxidation into two-carbon acetyl CoA molecules, which can then enter the Krebs cycle to generate ATP. If excess acetyl CoA is created and overloads the capacity of the Krebs cycle, the acetyl CoA can be used to synthesize ketone bodies. When glucose is limited, ketone bodies can be oxidized and used for fuel. Excess acetyl CoA generated from excess glucose or carbohydrate ingestion can be used for fatty acid synthesis or lipogenesis. Acetyl CoA is used to create lipids, triglycerides, steroid hormones, cholesterol, and bile salts. Lipolysis is the breakdown of triglycerides into glycerol and fatty acids, making them easier for the body to process. Choices: - one - five - two - three A:
three
