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:
(Answer)
bacteria and viruses
Ques: Answer the following question given this paragraph: The law of conservation of mass states that matter cannot be created or destroyed. Q: The law of conservation mass states that matter cannot be created or what? Choices: - changed - moved - observed - destroyed A:
Ans: destroyed
(Q).
Answer the following question given this paragraph: Wild plants and animals maintain a valuable pool of genetic variation . This is important because domestic species are genetically uniform. This puts them at great risk of dying out due to disease. Q: Unlike wild animals, what type of species are genetically uniform, making them more vulnerable to die-out from disease? Choices: - free-range species - urbane species - mammals - domestic species A:
(A).
domestic species
Ques:Answer the following question given this paragraph: example, if you hold an ice cube in your hand, the ice cube slowly melts as energy in the form of heat is transferred from your hand to the ice. As your hand loses energy, it starts to feel cold. Because of their interrelationships, energy, work, and heat have the same units. The SI unit of energy, work, and heat is the joule (J). A joule is a tiny amount of energy. For example, it takes about 4 J to warm 1 mL of H2O by 1C. Many processes occur with energy changes in thousands of joules, so the kilojoule (kJ) is also common. Another unit of energy, used widely in the health professions and everyday life, is the calorie (cal). The calorie was initially defined as the amount of energy needed to warm 1 g of H2O by 1C, but in modern times, the calorie is related directly to the joule, as follows: 1 cal = 4.184 J We can use this relationship to convert quantities of energy, work, or heat from one unit to another. The calorie is used in nutrition to express the energy content of foods. However, because a calorie is a rather small quantity, nutritional energies are usually expressed in kilocalories (kcal), also called Calories (capitalized; Cal). For example, a candy bar may provide 120 Cal (nutritional calories) of energy, which is equal to 120,000 cal. Proteins and carbohydrates supply 4 kcal/g, while fat supplies 9 kcal/g. Q: Another unit of energy, used widely in the health professions and everyday life, is _______? Choices: - carbs - body index - biomass ( cal ) - calorie ( cal ) A:

Ans:calorie ( cal )
Ques:Answer the following question given this paragraph: Electric potential energy comes from the position of a charged particle in an electric field. For example, when two negative charges are close together, they have potential energy because they repel each other and have the potential to push apart. If the charges actually move apart, their potential energy decreases. Electric charges always move spontaneously from a position where they have higher potential energy to a position where they have lower potential energy. This is like water falling over a dam from an area of higher to lower potential energy due to gravity. Q: What kind of energy comes from the position of a charged particle in an electric field? Choices: - solar energy - mechanical energy - thermal energy - potential energy A:

Ans:
potential energy
