Answer the following question given this paragraph: Figure above also shows how the size of waves is measured. The highest point of a wave is the crest. The lowest point is the trough. The vertical distance between a crest and a trough is the height of the wave. Wave height is also called amplitude. The horizontal distance between two crests is the wavelength. Both amplitude and wavelength are measures of wave size. Q: The highest point of a wave is called? Choices: - surge - threshold - frequency - crest A:
crest

Answer the following question given this paragraph: 10.6 Exercise and Muscle Performance Hypertrophy is an increase in muscle mass due to the addition of structural proteins. The opposite of hypertrophy is atrophy, the loss of muscle mass due to the breakdown of structural proteins. Endurance exercise causes an increase in cellular. Q: Loss of muscle mass due to breakdown of structural proteins is known as what? Choices: - distrophy - mutation - exhaustion - atrophy A:
(Answer)
atrophy
Ques: Answer the following question given this paragraph: Figure 3.20 The phospholipid bilayer is the major component of all cellular membranes. The hydrophilic head groups of the phospholipids face the aqueous solution. The hydrophobic tails are sequestered in the middle of the bilayer. Q: The major component of what cellular structures is the phospholipid bilayer? Choices: - cytoplasm - nuclei - ribosomes - cell membranes A:
Ans: cell membranes

Answer the following question given this paragraph: 24.2 Subphylum Urochordata The tunicates are located in this subphylum. Along with the subphylum Cephalochordata, these two subphyla make up the invertebrate chordates. Only the tunicate larvae have notochords, nerve cords, and postanal tails. Most adult tunicates are sessile, filter-feeders which retain their pharyngeal slits. Adult tunicates also develop a sac, called a tunic, which gives tunicates their name. Cilia beating within the turnicate cause water to enter the incurrent siphon. The water enters the body, passes through the pharyngeal slits, and leaves the body through the excurrent siphon. Undigested food is removed through the anus. Tunicates are hemaphrodites and can reproduce asexually through budding. In urochordates notochord is confined to larval tail. These lack cranium. These have an open type of circulatory system. Excretion is by neural gland,nephrocytes. Q: Adult tunicates also develop a sac, called a what? Choices: - hood - skirt - frill - tunic A:
(A).
tunic
Ques:Answer the following question given this paragraph: Q: Each proton has how many units of positive charge? Choices: - three - zero - two - one A:

Ans:one
Question: Answer the following question given this paragraph: Magnetic resonance imaging (NMR) devices use liquid nitrogen to cool the superconducting magnets. Nitrogen is a gas at room temperature and liquefies at -195.8C. Its neighbor on the periodic table (oxygen) boils at -182.95C. The interactions between nitrogen molecules (N 2 ) are weaker, so the boiling point is lower. Interactions between non-polar molecules depend on the degree of electron fluctuation within the molecule. Q: Magnetic resonance imaging devices use what to cool the superconducting magnets? Choices: - antifreeze - dry ice - fluorocarbons - liquid nitrogen A:
Answer:
liquid nitrogen
