Answer the following question given this paragraph: Homeostasis The goal of homeostasis is the maintenance of equilibrium around a specific value of some aspect of the body or its cells called a set point. While there are normal fluctuations from the set point, the body's systems will usually attempt to go back to this point. A change in the internal or external environment is called a stimulus and is detected by a receptor; the response of the system is to adjust the activities of the system so the value moves back toward the set point. For instance, if the body becomes too warm, adjustments are made to cool the animal. If glucose levels in the blood rise after a meal, adjustments are made to lower them and to get the nutrient into tissues that need it or to store it for later use. When a change occurs in an animal's environment, an adjustment must be made so that the internal environment of the body and cells remains stable. The receptor that senses the change in the environment is part of a feedback mechanism. The stimulustemperature, glucose, or calcium levelsis detected by the receptor. The receptor sends information to a control center, often the brain, which relays appropriate signals to an effector organ that is able to cause an appropriate change, either up or down, depending on the information the sensor was sending. Q: The human body wants to maintain equilibrium or balance, also known as what? Choices: - perfection - heterostasis - stability - homeostasis A:
(Answer)
homeostasis
Ques: Answer the following question given this paragraph: During early adulthood, people form intimate relationships and start careers. Serious health problems start showing up in middle adulthood and old age. Aging occurs as cells lose their ability to divide. Q: Aging occurs as cells lose their ability to do what? Choices: - grow - build - join - divide A:

(Q).
Answer the following question given this paragraph: Lysosomes are vesicles that are formed by the Golgi apparatus. They contain powerful enzymes that could break down (digest) the cell. Lysosomes break down harmful cell products, waste materials, and cellular debris and then force them out of the cell. They also digest invading organisms such as bacteria. Lysosomes also break down cells that are ready to die, a process called autolysis. Q: What is the name of vesicles that are formed by the golgi apparatus? Choices: - vessels - lymphocytes - capillaries - lysosomes A:
(A).
lysosomes
Ques:Answer the following question given this paragraph: Another way to classify matter is to describe it as a solid, a liquid, or a gas, which was done in the examples of solutions. These three descriptions, each implying that the matter has certain physical properties, represent the three phases of matter. A solid has a definite shape and a definite volume. Liquids ordinarily have a definite volume but not a definite shape; they take the shape of their containers. Gases have neither a definite shape nor a definite volume, and they expand to fill their containers. We encounter matter in each phase every day; in fact, we regularly encounter water in all three phases: ice (solid), water (liquid), and steam (gas). We know from our experience with water that substances can change from one phase to another if the conditions are right. Typically, varying the temperature of a substance (and, less commonly, the pressure exerted on it) can cause a phase change, a physical process in which a substance goes from one phase to another (Figure 1.4 "Boiling Water"). Phase changes have particular names depending on what phases are involved, as summarized in Table 1.1 "Phase Changes". Table 1.1 Phase Changes. Q: Another way to classify matter is to describe it as a solid, a liquid, or a gas, which was done in the examples of solutions. these three descriptions, each implying that the matter has certain physical properties, represent the three of these? Choices: - phases of mass - types of atoms - forms of substances - phases of matter A:

Ans:phases of matter
Answer the following question given this paragraph: The properties of matter, both physical and chemical, depend on the substances that matter is made of. Matter can exist either as a pure substance or as a combination of different substances. Q: Matter can exist either as a pure substance or as a combination of what? Choices: - Different Liquids - much substances - different vapors - different substances A:
different substances
