Answer the following question given this paragraph: Dipole-dipole forces are the attractive forces that occur between polar molecules. A molecule of hydrogen chloride has a partially positive hydrogen atom and a partially negative chlorine atom. In a collection of many hydrogen chloride molecules, they will align themselves so that the oppositely charged regions of neighboring molecules are near each other. Q: What are the attractive forces that occur between polar molecules called? Choices: - induced-dipole forces - particle - dipole forces - ion-dipole forces - dipole-dipole forces A:
dipole-dipole forces

Answer the following question given this paragraph: Fossils are the preserved remains of animals, plants, and other organisms from the distant past. Examples of fossils include bones, teeth, and impressions. By studying fossils, evidence for evolution is revealed. Paleontologists are scientists who study fossils to learn about life in the past. Fossils allow these scientists to determine the features of extinct species. Paleontologists compare the features of species from different periods in history. With this information, they try to understand how species have evolved over millions of years ( Figure below ). Q: What are the preserved remains of animals, plants, and other organisms called? Choices: - skulls - rocks - basalt - fossils A:
(Answer)
fossils
Ques: Answer the following question given this paragraph: Gamma rays are produced during gamma decay of an excited nucleus. During gamma decay, the nucleus emits a "packet" of energy called a gamma particle. Q: What is the"packet" of energy called that the nucleus emits during gamma decay? Choices: - transient particle - radioactive particle - ultraviolet particle - gamma particle A:
Ans: gamma particle
(Q).
Answer the following question given this paragraph: An underground layer of rock that is saturated with groundwater is called an aquifer . A diagram of an aquifer is shown in Figure below . Aquifers are generally found in porous rock, such as sandstone. Water infiltrates the aquifer from the surface. The water that enters the aquifer is called recharge. Q: What is the term for an underground layer of rock that is saturated with groundwater? Choices: - delta - river - bason - aquifer A:
(A).
aquifer
Ques:Answer the following question given this paragraph: Most reptiles have good eyesight and a keen sense of smell. Snakes smell scents in the air using their forked tongue (see Figure below ). This helps them locate prey. Some snakes have heat-sensing organs on their head that help them find endothermic prey, such as small mammals and birds. Staring into the Beautiful Cold-Blooded Eyes of Reptiles at http://www. environmentalgraffiti. com/news-reptile-eyes is a pictorial display of numerous reptile eyes. Q: Snakes use what anatomical structure to smell scents in the air? Choices: - forked tails - branched tongue - forked eyes - forked tongue A:

Ans:forked tongue
Answer the following question given this paragraph: Q: What are polymers composed of many sugar building blocks called? Choices: - monosaccarides - monomers - hydrocarbons - polysaccharides A:
polysaccharides
