Answer the following question given this paragraph: Q: What do drugs that alleviate symptoms of schizophrenia block? Choices: - adrenaline receptors - histamine receptors - ephedrine receptors - dopamine receptors A:
dopamine receptors

Answer the following question given this paragraph: There are three components that make up an electrochemical reaction. There must be a solution where redox reactions can occur. These reactions generally take place in water to facilitate electron and ion movement. A conductor must exist for electrons to be transferred. This conductor is usually some kind of wire so that electrons can move from one site to another. Ions also must be able to move through some form of salt bridge that facilitates ion migration. Q: What allows the electrons to move in an electrochemical system. Choices: - conduction - mass - magnetism - conductor A:
(Answer)
conductor
Ques: Answer the following question given this paragraph: Sensory neurons transmit nerve impulses from sense organs and internal organs to the brain via the spinal cord. In other words, they carry information about the inside and outside environment to the brain. Q: Sensory neurons transmit nerve impulses from sense organs and internal organs to the brain via the? Choices: - nervous system - nerve endings - spinal column - spinal cord A:
Ans: spinal cord
(Q).
Answer the following question given this paragraph: Purification of water for drinking and other uses is a complicated process. Heavy metals need to be removed, a process accomplished by addition of carbonates and sulfates. Lead contamination can present major health problems, especially for younger children. Lead sulfates and carbonates are very insoluble, so will precipitate out of solution very easily. Q: Is purifying water a simple or complicated process? Choices: - expensive - impossible - simple - complicated A:
(A).
complicated
Ques:Answer the following question given this paragraph: Just as the burning of wood releases energy in the form of heat, many other chemical reactions also release heat. There are also chemical reactions, such as photosynthesis in plants, which absorb energy in the form of heat. The study of energy changes in chemical reactions is called thermochemistry . The broader term thermodynamics also looks at how heat, work, and various forms of energy are related to one another. In this lesson, we will study the difference between reactions that absorb versus release heat as well as how to measure this change in energy. Q: What branch of physical science looks at how heat, work, and various forms of energy are related to one another? Choices: - photosynthesis - frigidity - transformations - thermodynamics A:

Ans:thermodynamics
Ques:Answer the following question given this paragraph: Chapter 30 1 Figure 30.7 A and B. The cortex, pith, and epidermis are made of parenchyma cells. 3 Figure 30.34 B. 4 C 6 C 8 A 10 B 12 A 14 B 16 C 18 B 20 D 22 C 24 C 26 C 27 Lawn grasses and other monocots have an intercalary meristem, which is a region of meristematic tissue at the base of the leaf blade. This is beneficial to the plant because it can continue to grow even when the tip of the plant is removed by grazing or mowing. 29 Stomata allow gases to enter and exit the plant. Guard cells regulate the opening and closing of stomata. If these cells did not function correctly, a plant could not get the carbon dioxide needed for photosynthesis, nor could it release the oxygen produced by photosynthesis. 31 In woody plants, the cork cambium is the outermost lateral meristem; it produces new cells towards the interior, which enables the plant to increase in girth. The cork cambium also produces cork cells towards the exterior, which protect the plant from physical damage while reducing water loss. 33 Annual rings can also indicate the climate conditions that prevailed during each growing season. 35 A tap root system. Q: Regulated by guard cells, stomata allow what to enter and exit the plant? Choices: - molecules - fluid - nutrients - gases A:

Ans:
gases
