Answer the following question given this paragraph: 11.8 Cohesion and Adhesion in Liquids: Surface Tension and Capillary Action Cohesion and Adhesion in Liquids Children blow soap bubbles and play in the spray of a sprinkler on a hot summer day. (See Figure 11.27. ) An underwater spider keeps his air supply in a shiny bubble he carries wrapped around him. A technician draws blood into a small-diameter tube just by touching it to a drop on a pricked finger. A premature infant struggles to inflate her lungs. What is the common thread? All these activities are dominated by the attractive forces between atoms and molecules in liquidsboth within a liquid and between the liquid and its surroundings. Attractive forces between molecules of the same type are called cohesive forces. Liquids can, for example, be held in open containers because cohesive forces hold the molecules together. Attractive forces between molecules of different types are called adhesive forces. Such forces cause liquid drops to cling to window panes, for example. In this section we examine effects directly attributable to cohesive and adhesive forces in liquids. Q: What does an underwater spider use to breathe and keep alive? Choices: - forehead air bubble - gills - metallic air bubble - shiny air bubble A:
(Answer)
shiny air bubble
Ques: Answer the following question given this paragraph: A peptide bond is the amide bond that occurs between the amino nitrogen of one amino acid and the carboxyl carbon of another amino acid. The resulting molecule is called a dipeptide. Notice that the particular side chains of each amino acid are irrelevant since the R groups are not involved in the peptide bond. Q: What is the amide bond that occurs between the amino nitrogen of one amino acid and the carboxyl carbon of another amino acid? Choices: - a covalent bond - a magnetite bond - a amino bond - a peptide bond A:
Ans: a peptide bond
(Q).
Answer the following question given this paragraph: Pneumonia is an illness that occurs when the alveoli, the tiny sacs in the lungs where gas exchange takes place, become inflamed and filled with fluid. When a person has pneumonia, gas exchange cannot occur properly across the alveoli. Pneumonia can be caused by many things. Infection by bacteria, viruses, fungi, or parasites can cause pneumonia. An injury caused by chemicals or a physical injury to the lungs can also cause pneumonia. Symptoms of pneumonia include cough, chest pain, fever, and difficulty breathing. Treatment depends on the cause of pneumonia. Bacterial pneumonia is treated with antibiotics. Q: What are the tiny sacs in the lungs where gas exchange takes place? Choices: - vacuoles - ganglion - chambers - alveoli A:
(A).
alveoli
Ques:Answer the following question given this paragraph: for low temperatures, where the phase can change from a gas to a liquid. The term "vapor" refers to the gas phase when it exists at a temperature below the boiling temperature. Q: The term "vapor" refers to the gas phase when it exists at a temperature below what? Choices: - contaminated temperature - freezing temperature - liquid temperature - boiling temperature A:

Ans:boiling temperature
Answer the following question given this paragraph: Pressure, volume, and temperature are related by the combined gas law. Q: Pressure, volume, and temperature are related by which law? Choices: - Law of Conservation - law of inertia - Murphy's Law - gas law A:
gas law
