Answer the following question given this paragraph: Sublimation and Deposition Some solids can transition directly into the gaseous state, bypassing the liquid state, via a process known as sublimation. At room temperature and standard pressure, a piece of dry ice (solid CO2) sublimes, appearing to gradually disappear without ever forming any liquid. Snow and ice sublime at temperatures below the melting point of water, a slow process that may be accelerated by winds and the reduced atmospheric pressures at high altitudes. When solid iodine is warmed, the solid sublimes and a vivid purple vapor forms (Figure 10.27). The reverse of sublimation is called deposition, a process in which gaseous substances condense directly into the solid state, bypassing the liquid state. The formation of frost is an example of deposition. Q: What is the process by which some solids transition directly into gases? Choices: - articulation - vaporization - amplification - sublimation A:
sublimation

Answer the following question given this paragraph: Q: What kind of fossils are excellent markers for correlating the ages of sedimentary rocks? Choices: - agonum - euglena - vertiscom - foram A:
(Answer)
foram
Ques: Answer the following question given this paragraph: You may have seen this sign beforemaybe in a hospital. The sign means there is danger of radiation in the area. Radiation consists of particles and energy that are given off by radioactive isotopes, which have unstable nuclei. But you don't have to go to a hospital to be exposed to radiation. There is radiation in the world all around you. Q: Radioactive isotopes are characterized by an unstable what? Choices: - shell - proton - electrons - nuclei A:
Ans: nuclei
(Q).
Answer the following question given this paragraph: Atoms are electrically neutral, but if they lose or gain electrons they become charged particles called ions. Q: What do atoms become if they lose or gain electrons? Choices: - toxins - particles - particulates - ions A:
(A).
ions
Ques:Answer the following question given this paragraph: The solubility of the majority of solid substances increases as the temperature increases. However, the effect is difficult to predict and varies widely from one solute to another. The temperature dependence of solubility can be visualized with the help of a solubility curve , a graph of the solubility vs. temperature (see Figure below ). Q: As temperature increases, the solubility of the majority of solid substances does what? Choices: - stays the same - reduces - mutates - increases A:

Ans:increases
Ques: Answer the following question given this paragraph: Organ systems are organized into the organism. The different organ systems work together to carry out all the life functions of the individual. For example, cardiovascular and respiratory systems work together to provide the individual with oxygen and rid it of carbon dioxide. Q: The different types of what systems work together to carry out all the life functions of the individual? Choices: - maturation systems - digestive systems - heartbeat systems - organ systems A:
Ans:
organ systems
