Answer the following question given this paragraph: Average global temperature has been rising for the past several decades. Q: Average global temperature has been doing what for the past several decades? Choices: - fluctuating - falling - stabilizing - rising A:
rising
Answer the following question given this paragraph: Segmented worms have a well-developed body cavity filled with fluid. This fluid-filled cavity serves as a hydroskeleton , a supportive structure that helps move the worm's muscles. Only the most primitive worms (the flatworms) lack a body cavity. Q: What is the name of the supportive structed that helps move a worm's muscles? Choices: - spongin - exoskeleton - pollenation - hydroskeleton A:
hydroskeleton
Q: Answer the following question given this paragraph: Root Growth and Anatomy Root growth begins with seed germination. When the plant embryo emerges from the seed, the radicle of the embryo forms the root system. The tip of the root is protected by the root cap, a structure exclusive to roots and unlike any other plant structure. The root cap is continuously replaced because it gets damaged easily as the root pushes through soil. The root tip can be divided into three zones: a zone of cell division, a zone of elongation, and a zone of maturation and differentiation (Figure 30.16). The zone of cell division is closest to the root tip; it is made up of the actively dividing cells of the root meristem. The zone of elongation is where the newly formed cells increase in length, thereby lengthening the root. Beginning at the first root hair is the zone of cell maturation where the root cells begin to differentiate into special cell types. All three zones are in the first centimeter or so of the root tip. Q: Why is the root cap continuously replaced in plants? Choices: - due to growth - due to pressure - due to rubbing - damage through pushing A:
A: damage through pushing
Question: Answer the following question given this paragraph: A cell is the simplest unit of structure and function of all living organisms. From the smallest bacteria to the largest whale, all life is made of at least one cell. Q: What is the simplest unit of structure and function of all living organisms called? Choices: - partical - molecule - atom - cell A:
Answer: cell

Answer the following question given this paragraph: Silver and ordinary table salt are two examples of chemical substances . A substance is matter that has a uniform and definite composition. All samples of substances, sometimes called pure substances, have identical properties. When chemists run a chemical reaction, they want to use pure materials so they know exactly what they are dealing with. They know that the reaction involves a specific substance, so they expect the same reaction to give the same results each time it is run. Q: Silver and ordinary table salt are two examples of chemical what? Choices: - organism - impurities - microbes - substances A:
**Answer**
substances

Answer the following question given this paragraph: Electromagnetic waves generally propagate out from a source in all directions, sometimes forming a complex radiation pattern. A linear antenna like this one will not radiate parallel to its length, for example. The wave is shown in one direction from the antenna in Figure 24.7 to illustrate its basic characteristics. Instead of the AC generator, the antenna can also be driven by an AC circuit. In fact, charges radiate whenever they are accelerated. But while a current in a circuit needs a complete path, an antenna has a varying charge distribution forming a standing wave, driven by the AC. The dimensions of the antenna are critical for determining the frequency of the radiated electromagnetic waves. This is a resonant phenomenon and when we tune radios or TV, we vary electrical properties to achieve appropriate resonant conditions in the antenna. Q: A current in a circuit needs a complete what? Choices: - cause - speed - stream - path A:
(Answer)
path
