Q: What part of the brain lies under the cerebrum and behind the brain stem? Read this paragraph and choose the correct option from the provided answers: The cerebellum is the next largest part of the brain. It lies under the cerebrum and behind the brain stem. The cerebellum controls body position, coordination, and balance. Whether you are riding a bicycle or writing with a pen, you are using your cerebellum. Choices: - spinal cord - thymus - medulla - cerebellum A:
cerebellum

Q: A wildfire clears a forest of vegetation and animal life, returning their nutrients to the ground leaving a foundation for rapid recolonization. what is this a classic example of? Read this paragraph and choose the correct option from the provided answers: Secondary succession A classic example of secondary succession occurs in oak and hickory forests cleared by wildfire (Figure 19.27). Wildfires will burn most vegetation, and unless the animals can flee the area, they are killed. Their nutrients, however, are returned to the ground in the form of ash. Thus, although the community has been dramatically altered, there is a soil ecosystem present that provides a foundation for rapid recolonization. Before the fire, the vegetation was dominated by tall trees with access to the major plant energy resource: sunlight. Their height gave them access to sunlight while also shading the ground and other low-lying species. After the fire, though, these trees are no longer dominant. Thus, the first plants to grow back are usually annual plants followed within a few years by quickly growing and spreading grasses and other pioneer species. Due, at least in part, to changes in the environment brought on by the growth of grasses and forbs, over many years, shrubs emerge along with small pine, oak, and hickory trees. These organisms are called intermediate species. Eventually, over 150 years, the forest will reach its equilibrium point and resemble the community before the fire. This equilibrium state is referred to as the climax community, which will remain until the next disturbance. The climax community is typically characteristic of a given climate and geology. Although the community in equilibrium looks the same once it is attained, the equilibrium is a dynamic one with constant changes in abundance and sometimes species identities. The return of a natural ecosystem after agricultural activities is also a well-documented secondary succession process. Choices: - primary succession - typical succession - cause succession - secondary succession A:
(A).
secondary succession

Question: Q: Because heating results in a greater fraction of molecules having the necessary kinetic energy to escape the surface of the liquid, what occurs more quickly when liquid is heated? Read this paragraph and choose the correct option from the provided answers: A given liquid will evaporate more quickly when it is heated. This is because the heating process results in a greater fraction of the liquid's molecules having the necessary kinetic energy to escape the surface of the liquid. The Figure below shows the kinetic energy distribution of liquid molecules at two temperatures. The numbers of molecules that have the required kinetic energy to evaporate are shown in the shaded area under the curve at the right. The higher temperature liquid (T 2 ) has more molecules that are capable of escaping into the vapor phase than the lower temperature liquid (T 1 ). Choices: - oxidation - expansion - absorption - evaporation A:
Answer:
evaporation
