Q: Answer the following question given this paragraph: 26.4 Microscopes Although the eye is marvelous in its ability to see objects large and small, it obviously has limitations to the smallest details it can detect. Human desire to see beyond what is possible with the naked eye led to the use of optical instruments. In this section we will examine microscopes, instruments for enlarging the detail that we cannot see with the unaided eye. The microscope is a multiple-element system having more than a single lens or mirror. (See Figure 26.15) A microscope can be made from two convex lenses. The image formed by the first element becomes the object for the second element. The second element forms its own image, which is the object for the third element, and so on. Ray tracing helps to visualize the image formed. If the device is composed of thin lenses and mirrors that obey the thin lens equations, then it is not difficult to describe their behavior numerically. Q: A microscope can be made from two of what kind of lenses? A:

OPTIONS:
- inner
- angular
- outer
- convex

A: convex

input: OPTIONS:
- sedimentation
- oxidation
- igneous extrusion
- metamorphism Now, answer this question: Answer the following question given this paragraph: Metamorphism does not cause a rock to melt completely. It only causes the minerals to change by heat or pressure. Q: What process does not cause a rock to melt completely, instead causing the minerals to change by heat or pressure? A:
A:
output: metamorphism

Answer the following question given this paragraph: Disaccharides A disaccharide is a pair of monosaccharides. Disaccharides are formed via dehydration synthesis, and the bond linking them is referred to as a glycosidic bond (glyco- = "sugar"). Three disaccharides (shown in Figure 2.19) are important to humans. These are sucrose, commonly referred to as table sugar; lactose, or milk sugar; and maltose, or malt sugar. As you can tell from their common names, you consume these in your diet; however, your body cannot use them directly. Instead, in the digestive tract, they are split into their component monosaccharides via hydrolysis. Q: A disaccharide is a pair of monosaccharides. disaccharides are formed via dehydration synthesis, and the bond linking them is referred to as a glycosidic bond (glyco- = "sugar"). three disaccharides (shown in figure 2.19) are important to humans. these are sucrose, commonly referred to as table sugar; lactose, or milk sugar; and maltose, or this? A:

OPTIONS:
- fruit sugar
- saccharin
- sucralose
- malt sugar

Answer: malt sugar

Problem: OPTIONS:
- pinworm sounds
- whooping sounds
- choanocyte sounds
- korotkoff sounds
Q: Answer the following question given this paragraph: 12.5 The Onset of Turbulence Sometimes we can predict if flow will be laminar or turbulent. We know that flow in a very smooth tube or around a smooth, streamlined object will be laminar at low velocity. We also know that at high velocity, even flow in a smooth tube or around a smooth object will experience turbulence. In between, it is more difficult to predict. In fact, at intermediate velocities, flow may oscillate back and forth indefinitely between laminar and turbulent. An occlusion, or narrowing, of an artery, such as shown in Figure 12.17, is likely to cause turbulence because of the irregularity of the blockage, as well as the complexity of blood as a fluid. Turbulence in the circulatory system is noisy and can sometimes be detected with a stethoscope, such as when measuring diastolic pressure in the upper arm's partially collapsed brachial artery. These turbulent sounds, at the onset of blood flow when the cuff pressure becomes sufficiently small, are called Korotkoff sounds. Aneurysms, or ballooning of arteries, create significant turbulence and can sometimes be detected with a stethoscope. Heart murmurs, consistent with their name, are sounds produced by turbulent flow around damaged and insufficiently closed heart valves. Ultrasound can also be used to detect turbulence as a medical indicator in a process analogous to Doppler-shift radar used to detect storms. Q: Turbulent sounds, at the onset of blood flow when the cuff pressure becomes sufficiently small are called? A:
Answer: korotkoff sounds

Problem:OPTIONS:
- nitrogen catabolism
- conductive substitution reactions
- nucleophobic reactions
- nucleophilic substitution reactions

Answer the following question given this paragraph: molecular masses. Primary amines tend to have boiling points intermediate between those of the corresponding alcohol and alkane. Moreover, secondary and tertiary amines have lower boiling points than primary amines of comparable molecular mass. Tertiary amines form cations analogous to the ammonium ion (NH 4+), in which all four H atoms are replaced by alkyl groups. Such substances, calledquaternary ammonium salts, can be chiral if all four substituents are different. (Amines with three different substituents are also chiral because the lone pair of electrons represents a fourth substituent. ) Alkylamines can be prepared by nucleophilic substitution reactions of alkyl halides with ammonia or other amines: Equation 24.12. Q: Which reaction between alkyl halides and ammonia makes alkylamines? A:
****
A: nucleophilic substitution reactions

Problem:OPTIONS:
- liver
- gall bladder
- small intestine
- large intestine

Answer the following question given this paragraph: The large intestine eliminates food wastes that remain after digestion takes place. Q: What eliminates food wastes that remain after digestion takes place? A:

A:
