Answer the following question given this paragraph: Lipids A lipid is one of a highly diverse group of compounds made up mostly of hydrocarbons. The few oxygen atoms they contain are often at the periphery of the molecule. Their nonpolar hydrocarbons make all lipids hydrophobic. In water, lipids do not form a true solution, but they may form an emulsion, which is the term for a mixture of solutions that do not mix well. Q: A lipid is one of a highly diverse group of compounds made up mostly of what? Choices: - nucleic acid - amines - proteins - hydrocarbons A:
hydrocarbons
Answer the following question given this paragraph: Halide minerals are salts. They form when salt water evaporates. This mineral class includes more than just table salt. Halide minerals may contain the elements fluorine, chlorine, bromine, or iodine. Some halide minerals combine with metal elements. Common table salt is a halide mineral that contains the elements chlorine and sodium. Fluorite is a type of halide that contains fluorine and calcium. Fluorite can be found in many colors. If you shine an ultraviolet light on fluorite, it will glow!. Q: What type of minerals form when salt water evaporates? Choices: - sulfide - carbonate - fermite - halide A:
halide
Q: Answer the following question given this paragraph: Organisms that have a diploid life cycle spend the majority of their lives as diploid adults. All diploid adults inherit half of their DNA from each parent. When they are ready to reproduce, diploid reproductive cells undergo meiosis and produce haploid gametes. These gametes then fuse through fertilization and produce a diploid zygote, which immediately enters G 1 of the cell cycle. Next, the zygote's DNA is replicated. Finally, the processes of mitosis and cytokinesis produce two genetically identical diploid cells. Through repeated rounds of growth and division, this organism becomes a diploid adult and the cycle continues. This is the life cycle of humans. Q: What is the series of changes in the life of an organism? Choices: - insect metamorphosis - evolution - circle of life - life cycle A:
A: life cycle
Question: Answer the following question given this paragraph: People often complain when the weather forecast is wrong. Weather forecasts today, however, are much more accurate than they were just 20 years ago. Scientists who study and forecast the weather are called meteorologists. How do they predict the weather?. Q: What are scientists called who study the weather and give forecasts? Choices: - climatologists - geologists - botanists - meteorologists A:
Answer: meteorologists

Answer the following question given this paragraph: You may have seen this sign beforemaybe in a hospital. The sign means there is danger of radiation in the area. Radiation consists of particles and energy that are given off by radioactive isotopes, which have unstable nuclei. But you don't have to go to a hospital to be exposed to radiation. There is radiation in the world all around you. Q: Radioactive isotopes are characterized by an unstable what? Choices: - shell - proton - electrons - nuclei A:
**Answer**
nuclei
Answer the following question given this paragraph: Q: Energy that is released when a chemical reaction takes place is known as what? Choices: - liquid energy - consequence energy - thermal energy - chemical energy A:
