Answer the following question given this paragraph: Natural gas is delivered to homes, where it is used for cooking and heating. Natural gas is also a major energy source for powering turbines to make electricity. Natural gas releases most of its energy as heat when it burns. The power plant is able to use this heat, either in the form of hot gases or steam, to spin turbines. The spinning turbines turn generators, and the generators create electricity. Q: What type of gas is delivered to homes to use for cooking and heating? Choices: - fluid gas - compounded gas - nuetralized gas - natural gas A:
natural gas

Answer the following question given this paragraph: Jean Baptiste Lamarck (17441829) was an important French naturalist. He was one of the first scientists to propose that species change over time. However, Lamarck was wrong about how species change. His idea of the inheritance of acquired characteristics is incorrect. Traits an organism develops during its own life time cannot be passed on to offspring, as Lamarck believed. Q: How did lamarck believe species change over time? Choices: - became larger - lose of acquired traits - ecological of acquired characteristics - inheritance of acquired characteristics A:
(Answer)
inheritance of acquired characteristics
Ques: Answer the following question given this paragraph: Glycogen is a branched polymer of glucose and serves as energy storage in animals. Q: What is a branded polymer that serves as energy storage in animal? Choices: - triglyceride - hydrocarbon - pathogen - glycogen A:
Ans: glycogen

Answer the following question given this paragraph: Like animals, plants have organs that are specialized to carry out complex functions. An organ is a structure composed of more than one type of tissue. A tissue, in turn, is a group of cells of the same kind that do the same job. In this lesson, you will read about the tissues that do the important work of plants. The cells that make up plant tissues are described first. Q: What is the term for a structure composed of more than one type of tissue? Choices: - marrow - system - cortex - organ A:
(A).
organ
Ques:Answer the following question given this paragraph: Start right above point on the temperature axis and follow the red line vertically. At very low pressure, the particles of the substance are far apart from one another and the substance is in the gas state. As the pressure is increased, the particles of the substance are forced closer and closer together. Eventually the particles are pushed so close together that attractive forces cause the substance to condense into the liquid state. Continually increasing the pressure on the liquid will eventually cause the substance to solidify. For the majority of substances, the solid state is denser than the liquid state and so putting a liquid under great pressure will cause it to turn into a solid. The line segment represents the process of sublimation, where the substance changes directly from a solid to a gas. At a sufficiently low pressure, the liquid phase does not exist. The point labeled is called the triple point . The triple point is the one condition of temperature and pressure where the solid, liquid, and vapor states of a substance can all coexist at equilibrium. Q: Continually increasing the pressure on the liquid will eventually cause the substance to do what? Choices: - explode - erode - transform - solidify A:

Ans:solidify
Ques:Answer the following question given this paragraph: Q: What must happen for two ions to form an ionic bond? Choices: - two ions need to have the same charge - Two ions need to be the same size - two ions need to have neutral charges - two ions need to have opposite charges A:

Ans:
two ions need to have opposite charges
