Q: Molecules in the gas phase can collide with the liquid surface and reenter the liquid via what? Read this paragraph and choose the correct option from the provided answers: pressure above the liquid. Molecules in the gas phase can collide with the liquid surface and reenter the liquid via condensation. Eventually, a steady state is reached in which the number of molecules evaporating and condensing per unit time is the same, and the system is in a state of dynamic equilibrium. Under these conditions, a liquid exhibits a characteristic equilibrium vapor pressure that depends only on the temperature. We can express the nonlinear relationship between vapor pressure and temperature as a linear relationship using the ClausiusClapeyron equation. This equation can be used to calculate the enthalpy of vaporization of a liquid from its measured vapor pressure at two or more temperatures. Volatile liquids are liquids with high vapor pressures, which tend to evaporate readily from an open container; nonvolatile liquids have low vapor pressures. When the vapor pressure equals the external pressure, bubbles of vapor form within the liquid, and it boils. The temperature at which a substance boils at a pressure of 1 atm is its normal boiling point. Choices: - fermentation - combustion - liquidation - condensation A:
(Answer)
condensation

Q: The entry of food into the esophagus marks the beginning of the esophageal phase of deglutition and the initiation of this? Read this paragraph and choose the correct option from the provided answers: The Esophageal Phase The entry of food into the esophagus marks the beginning of the esophageal phase of deglutition and the initiation of peristalsis. As in the previous phase, the complex neuromuscular actions are controlled by the medulla oblongata. Peristalsis propels the bolus through the esophagus and toward the stomach. The circular muscle layer of the muscularis contracts, pinching the esophageal wall and forcing the bolus forward. At the same time, the longitudinal muscle layer of the muscularis also contracts, shortening this area and pushing out its walls to receive the bolus. In this way, a series of contractions keeps moving food toward the stomach. When the bolus nears the stomach, distention of the esophagus initiates a short reflex relaxation of the lower esophageal sphincter that allows the bolus to pass into the stomach. During the esophageal phase, esophageal glands secrete mucus that lubricates the bolus and minimizes friction. Choices: - relaxation - digestion - propagation - peristalsis A:
(A).
peristalsis

Ques:Q: Eventually the parent cell will pinch apart to form two identical types of what cells? Read this paragraph and choose the correct option from the provided answers: Cell division is relatively simple in prokaryotic cells. The two cells divide by binary fission. Green and orange lines indicate old and newly-generated bacterial cell walls, respectively. Eventually the parent cell will pinch apart to form two identical daughter cells. Left, growth at the center of bacterial body, such as in Bacillus subtilis and E. coli . Right, apical growth from the ends of the bacterial body, such as in Corynebacterium diphtheriae . Choices: - brother cells - father cells - son cells - daughter cells A:

Ans:daughter cells

Q: Combined substances are either compounds or what? Read this paragraph and choose the correct option from the provided answers: Ahhhh! A tall glass of ice-cold lemonade is really refreshing on a hot day. Lemonade is a combination of lemon juice, water, and sugar. Do you know what kind of matter lemonade is? It's obviously not an element because it consists of more than one substance. Is it a compound? Not all combined substances are compounds. Someincluding lemonadeare mixtures. Choices: - solutions - concentrations - combinations - mixtures A:
mixtures
