Answer the following question given this paragraph: Chemoheterotrophs are organisms that get their energy source and carbon source from organic sources. Chemoheterotrophs must consume organic building blocks that they are unable to make themselves. Most get their energy from organic molecules such as sugars. This nutritional mode is very common among eukaryotes, including humans. Q: Which organisms get their energy source and carbon source from organic sources? Choices: - herbivores - ectomorphs - sporozoans - chemoheterotrophs A:
chemoheterotrophs

Answer the following question given this paragraph: Properties of matter fall into one of two categories. If the property depends on the amount of matter present, it is an extensive property. The mass and volume of a substance are examples of extensive properties; for instance, a gallon of milk has a larger mass and volume than a cup of milk. The value of an extensive property is directly proportional to the amount of matter in question. If the property of a sample of matter does not depend on the amount of matter present, it is an intensive property. Temperature is an example of an intensive property. If the gallon and cup of milk are each at 20 C (room temperature), when they are combined, the temperature remains at 20 C. As another example, consider the distinct but related properties of heat and temperature. A drop of hot cooking oil spattered on your arm causes brief, minor discomfort, whereas a pot of hot oil yields severe burns. Both the drop and the pot of oil are at the same temperature (an intensive property), but the pot clearly contains much more heat (extensive property). Q: Extensive and intensive are categories of properties that apply to what? Choices: - volume - weight - height - matter A:
(Answer)
matter
Ques: Answer the following question given this paragraph: Figure 1.1 Galaxies are as immense as atoms are small. Yet the same laws of physics describe both, and all the rest of naturean indication of the underlying unity in the universe. The laws of physics are surprisingly few in number, implying an underlying simplicity to nature's apparent complexity. (credit: NASA, JPL-Caltech, P. Barmby, Harvard-Smithsonian Center for Astrophysics). Q: The laws of what field of science apply to galaxies and atoms, an indication of the underlying unity in the universe? Choices: - anthropology - geology - astronomy - physics A:
Ans: physics
(Q).
Answer the following question given this paragraph: Rutherford proposed a new atomic model that described the atom as comprised of a positively charged nucleus surrounded by negatively charged electrons. In this model, most of the atom was thought to be empty space. *Protons are positively charged and have a relatively large mass compared to electrons. Protons can be found in the nucleus of the atom. Q: Where are protons found in the atom? Choices: - within electrons - in the orbital - outside the nucleus - in the nucleus A:
(A).
in the nucleus
Ques:Answer the following question given this paragraph: Tides are not unique to Earth but occur in many astronomical systems. The most extreme tides occur where the gravitational force is the strongest and varies most rapidly, such as near black holes (see Figure 6.26). A few likely candidates for black holes have been observed in our galaxy. These have masses greater than the Sun but have diameters only a few kilometers across. The tidal forces near them are so great that they can actually tear matter from a companion star. Q: The tidal forces near what celestial phenomena are so great they can actually tear matter from a companion star? Choices: - dwarf star - large holes - wormholes - black holes A:

Ans:black holes
Question: Answer the following question given this paragraph: Without communication, animals would not be able to live together in groups. Animals that live in groups with other members of their species are called social animals. Social animals include many species of insects, birds, and mammals. Specific examples are ants, bees, crows, wolves, and human beings. Q: Animals that live in groups with other members of their species are called what? Choices: - available animals - grouping animals - aggressive animals - social animals A:
Answer:
social animals
