Q: The type of what dictates how far it can penetrate into matter, such as lead or human flesh? Read this paragraph and choose the correct option from the provided answers: The type of radiation, which dictates how far it can penetrate into matter 2. The energy of the individual particles or photons 3. The number of particles or photons that strike a given area per unit time 4. The chemical nature of the substance exposed to the radiation The relative abilities of the various forms of ionizing radiation to penetrate biological tissues are illustrated inFigure 20.12 "Depth of Penetration of Ionizing Radiation". Because of its high charge and mass, radiation interacts strongly with matter. Consequently, it does not penetrate deeply into an object, and it can be stopped by a piece of paper, clothing, or skin. In contrast, rays, with no charge and essentially no mass, do not interact strongly with matter and penetrate deeply into most objects, including the human body. Several inches of lead or more than 12 inches of special concrete are needed to completely stop rays. Because particles are intermediate in mass and charge between particles and . Choices: - insulation - evaporation - specific gravity - radiation A:
radiation

Q: Pauropods, presumed relatives of millipedes usually found in soil, leaf litter and other moist places, live on all continents except what? Read this paragraph and choose the correct option from the provided answers: The pauropods are typically 0.5-2.0 mm long and live on all continents except Antarctica. They are usually found in soil, leaf litter, or other moist places. They feed on fungi and decaying organic matter, and are essentially harmless. Adult pauropods have 11 or 12 body segments and 9-11 pairs of legs. They also possess unique forked antennae and a distinctive pattern of movement characterized by rapid burst of movement and frequent abrupt changes in direction. Over 700 species have been described, and they are believed to be closely related to millipedes. Choices: - Europe - inland - Ocean - antarctica A:
(Answer)
antarctica

Ques: Q: What are two common weather characteristics of hurricanes? Read this paragraph and choose the correct option from the provided answers: Volcanoes and earthquakes are common at active margins. Active margins are near plate boundaries. Choices: - low winds and sandstorms - high winds and snowfall - small winds and rainfall - high winds and rainfall A:
Ans: high winds and rainfall

Q: Varicose veins are veins that become enlarged because the valves no longer do this? Read this paragraph and choose the correct option from the provided answers: Blood travels through the bicuspid valve to the left atrium. Both the aortic and the pulmonary valves are semilunar valves. The mitral valve is an atrioventricular valve. Figure 40.17 Varicose veins are veins that become enlarged because the valves no longer close properly, allowing blood to flow backward. Varicose veins are often most prominent on the legs. Why do you think this is the case?. Choices: - shrink properly - open properly - enlarge properly - close properly A:
(A).
close properly

Ans:demography

Most also have six neutrons, but some have seven or eight neutrons. What is the mass number of a carbon isotope that has seven neutrons?. Choices: - one - two - eight - six A:

Ans:
