Answer the following question given this paragraph: Q: Large increases in the diversity of life have resulted from adaptive radiations that followed what? Choices: - mass mutations - mass migrations - glaciers - mass extinctions A:
mass extinctions
Answer the following question given this paragraph: Organisms evolve adaptations that help them survive in the climate of the biome where they live. For example, in biomes with arid climates, plants may have special tissues for storing water (see Figure below ). The desert animals pictured in Figure below also have adaptations for a dry climate. Q: A plant that forms special tissues for storing water in an arid climate is an example of the plant evolving what? Choices: - consciousness - additions - divergence - adaptations A:
adaptations
Q: Answer the following question given this paragraph: Discussion Quite a trip (if it survives)! Note that this distance is the total distance traveled by the fly. Displacement is actually zero for complete revolutions because they bring the fly back to its original position. The distinction between total distance traveled and displacement was first noted in One-Dimensional Kinematics. Q: Where was the distinction between total distance traveled and displacement first noted? Choices: - uncertainty principle - Newton's first law - string theory - one-dimensional kinematics A:
A: one-dimensional kinematics
Question: Answer the following question given this paragraph: An online guide from the University of Illinois about air masses and fronts is found here: http://ww2010. atmos. uiuc. edu/%28Gh%29/guides/mtr/af/home. rxml . Q: What is essential for cellular respiration for all aerobic organisms? Choices: - nitrogen - water - carbon - oxygen A:
Answer: oxygen
*Question*
Answer the following question given this paragraph: There are two basic body plans in cnidarians. They are called the polyp and medusa. Both are shown in Figure below . The polyp has a tubular body and is usually sessile. The medusa (plural, medusae ) has a bell-shaped body and is typically motile. Some cnidarian species alternate between polyp and medusa forms. Other species exist in just one form or the other. Q: There are two basic body plans in cnidarians which are called the polyp and what else? Choices: - hydra - spore - stoma - medusa A:
**Answer**
medusa
Q: Answer the following question given this paragraph: The generation of an isolated but open system, which we might call a protocell, was a critical step in the origin of life. Such an isolated system has important properties that are likely to have facilitated the further development of life. For example, because of the membrane boundary, changes that occur within one such structure will not be shared with neighboring systems. Rather, they accumulated in, and favor the survival of, one system over its neighbors. Such systems can also reproduce in a crude way by fragmentation. If changes within one such system improved its stability, its ability to accumulate resources, or its ability to survive and reproduce, that system, and its progeny, would be likely to become more common. As these changes accumulate and are passed from parent to offspring, the organisms will inevitably evolve, as we will see in detail in the next chapter. As in living systems today, the earliest steps in the formation of the first organisms required a source of energy to maintain the non-equilibrium living system. There are really two choices for the source of this energy, either light (electromagnetic radiation from the sun) or thermodynamically unstable chemicals present in the environment. There have been a number of plausible scenarios, based on various observations, for the steps leading to life. For example, a recent study based on the analysis of the genes (and the proteins that they encode) found in modern organisms, suggests that the last universal common ancestor (LUCA) arose in association with hydrothermal vents.60 But whether this reflects LUCA or an ancestor of LUCA that became adapted to living is association with hydrothermal vents is difficult (and perhaps impossible) to resolve unambiguously, particularly since LUCA lived ~3.4-3.8 billion years ago and cannot be studied directly. Mapping the history of life on earth Assuming, as seems likely, that life arose spontaneously, we can now look at what we know about the fossil record to better understand the diversification of... Q: What is the theoretical event that began the universe often called? Choices: - Coreolis effect - dark matter - string theory - big bang A:
A: big bang
