Answer the following question given this paragraph: Homeostatic Process The goal of homeostasis is the maintenance of equilibrium around a point or value 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 deviation parameter toward the set point. For instance, if the body becomes too warm, adjustments are made to cool the animal. If the blood's glucose rises after a meal, adjustments are made to lower the blood glucose level by getting the nutrient into tissues that need it or to store it for later use. Q: The goal of homeostasis is the maintenance of what, around a point or value called a set point? Choices: - agitation - steadiness - imbalance - equilibrium A:
equilibrium
Answer the following question given this paragraph: Today most people realize that microorganisms, such as bacteria or viruses, are the cause of disease. This concept is known as the germ theory of disease, one of the few scientific theories in the field of the life sciences. Although it seems obvious now, people did not always understand the cause of disease. How does a theory such as this become established?. Q: What are the two most common causes of diseases? Choices: - bacteria and protazoa - viruses and protazoa - nutritional deficiencies - bacteria and viruses A:
bacteria and viruses
Q: Answer the following question given this paragraph: Q: Ciliary muscles control the shape of the lens, which bends light and focuses it on what? Choices: - the pupil - the vitreous fluid - the cornea - the retina A:
A: the retina
Question: Answer the following question given this paragraph: In general, the process of interest is taking place in the system, and there are no changes in the composition of the surroundings. However, the temperature of the surroundings does generally change. Entropy changes in the surroundings are determined primarily by the flow of heat into or out of the system. In an exothermic process, heat flows into the surroundings, increasing the kinetic energy of the nearby particles. For an exothermic reaction, S surr is positive. Conversely, heat flows from the surroundings into the system during an endothermic process, lowering the kinetic energy available to the surroundings and resulting in a negative value for S surr . Q: In what type of process does heat flow into its surroundings and cause an increase in kinetic energy? Choices: - biochemical process - chemical process - oscillating process - exothermic process A:
Answer: exothermic process

Answer the following question given this paragraph: Most adults experience at least some hearing loss as they get older. The most common cause is exposure to loud sounds, which damage hair cells. The louder a sound is, the less exposure is needed for damage to occur. Even a single brief exposure to a sound louder than 115 decibels can cause hearing loss. Figure below shows the relationship between loudness, exposure time, and hearing loss. Q: Because it damages hair cells, what is the most cause of hearing loss in adults? Choices: - bacteria - ear wax - water in the ears - exposure to noise A:
**Answer**
exposure to noise

Answer the following question given this paragraph: Nonmetals tend to gain electrons in chemical reactions and have a high attraction to electrons within a compound. The most reactive nonmetals reside in the upper right portion of the periodic table. Since the noble gases are an unusually unreactive group, the element fluorine is the most reactive nonmetal. It is also not found in nature as a free element. Fluorine gas reacts explosively with many other elements and compounds and is considered to be one of the most dangerous known substances. Q: What group of gases are unusually unreactive? Choices: - volcanic gases - greenhouse gases - halogens - noble gases A:
**Answer**
noble gases
