Answer the following question given this paragraph: A concave mirror is shaped like the inside of a bowl. The type of image it forms depends on where the object is relative to the focal point. The image may be real, upside down, and reduced in size; or it may be virtual, right-side up, and enlarged. Q: What do you call a mirror shaped like the inside of a bowl? Choices: - convex - circular - curved - concave A:
concave

Answer the following question given this paragraph: As a child, you may have made suspensions such as mixtures of mud and water, flour and water, or a suspension of solid pigments in water, known as tempera paint. These suspensions are heterogeneous mixtures composed of relatively large particles that are visible (or that can be seen with a magnifying glass). They are cloudy, and the suspended particles settle out after mixing. On the other hand, when we make a solution, we prepare a homogeneous mixture in which no settling occurs and in which the dissolved species are molecules or ions. Solutions exhibit completely different behavior from suspensions. A solution may be colored, but it is transparent, the molecules or ions are invisible, and they do not settle out on standing. A group of mixtures called colloids (or colloidal dispersions) exhibit properties intermediate between those of suspensions and solutions (Figure 11.30). The particles in a colloid are larger than most simple molecules; however, colloidal particles are small enough that they do not settle out upon standing. Q: Distinct from a suspension, a solution is considered what type of mixture? Choices: - gaseous - continuous - heterogeneous - homogeneous A:
(Answer)
homogeneous
Ques: Answer the following question given this paragraph: As shown in Figure below , transcription is controlled by regulatory proteins . The proteins bind to regions of DNA, called regulatory elements , which are located near promoters. After regulatory proteins bind to regulatory elements, they can interact with RNA polymerase, the enzyme that transcribes DNA to mRNA. Regulatory proteins are typically either activators or repressors. Q: Dna transcription is controlled by what type of proteins? Choices: - essential - digested - genetic - regulatory A:
Ans: regulatory

Answer the following question given this paragraph: The thermometer was developed a short time after the barometer made it possible to study pressure in a quantitative manner. Although crude thermometers had been available for quite some time, Daniel Fahrenheit constructed a more accurate thermometer in 1724 using mercury in glass. Because the height of the mercury in the thermometer was a relative measure, certain fixed points needed to be defined. Originally, Fahrenheit defined a 1:1:1 mixture of ice, salt, and ammonium chloride as 0F, and the freezing/melting point of ice as 32F. On this scale, the normal temperature of the human body is 96F, and the boiling point of water is 212C. The modern Fahrenheit scale is defined in terms of the normal freezing and boiling points of water. Q: What instrument made it possible to study pressure quantitatively? Choices: - anemometer - seismograph - thermometer - barometer A:
(A).
barometer

Q: What are the most numerous and diverse biochemical compounds? Choices: - lipids - acids - Carbohydrates - proteins A:

Ans:proteins
Question: Answer the following question given this paragraph: Consider the simple ramp in Figure below . A ramp can be used to raise an object up off the ground. The input distance is the length of the sloped surface of the ramp. The output distance is the height of the ramp, or the vertical distance the object is raised. Therefore, the ideal mechanical advantage of the ramp is:. Q: The length of the sloped surface of a ramp is referred to as what? Choices: - accumulation distance - output distance - furlong - input distance A:
Answer:
input distance
