Answer the following question given this paragraph: Algae play significant roles as producers in aquatic ecosystems. Microscopic forms live suspended in the water column. They are the main component of phytoplankton . As such, they contribute to the food base of most marine ecosystems. Q: What is the main component of phytoplankton? Choices: - sponge - coral - seawater - algae A:
algae
Answer the following question given this paragraph: Sweating regulates body temperature. The composition of the sweat determines whether body odor is a byproduct of sweating. Visit this link (http://openstaxcollege. org/l/sweating) to learn more about sweating and body odor. Q: What is the beneficial function to the body of sweating? Choices: - pheromone release - diuretic effect - calorie loss - regulating body temperature A:
regulating body temperature
Q: Answer the following question given this paragraph: When an earthquake occurs under the ocean, it sends waves through the water as well as the ground. When the energy of the earthquake reaches shore, it forms a huge wave called a tsunami. Q: When the energy of the earthquake reaches shore, it forms a huge wave called? Choices: - a surge - a typhoon - a tidal wave - a tsunami A:
A: a tsunami
Question: Answer the following question given this paragraph: Introduction to Dynamics: Newton's Laws of Motion Motion draws our attention. Motion itself can be beautiful, causing us to marvel at the forces needed to achieve spectacular motion, such as that of a dolphin jumping out of the water, or a pole vaulter, or the flight of a bird, or the orbit of a satellite. The study of motion is kinematics, but kinematics only describes the way objects movetheir velocity and their acceleration. Dynamics considers the forces that affect the motion of moving objects and systems. Newton's laws of motion are the foundation of dynamics. These laws provide an example of the breadth and simplicity of principles under which nature functions. They are also universal laws in that they apply to similar situations on Earth as well as in space. Isaac Newton's (16421727) laws of motion were just one part of the monumental work that has made him legendary. The development of Newton's laws marks the transition from the Renaissance into the modern era. This transition was characterized by a revolutionary change in the way people thought about the physical universe. For many centuries natural philosophers had debated the nature of the universe based largely on certain rules of logic with great weight given to the thoughts of earlier classical philosophers such as Aristotle (384322 BC). Among the many great thinkers who contributed to this change were Newton and Galileo. Q: Whose laws of motion are the foundation of dynamics? Choices: - aristotle - einstein - bell - newton A:
Answer: newton

Answer the following question given this paragraph: A battery is an electrochemical cell or series of cells that produces an electric current. In principle, any galvanic cell could be used as a battery. An ideal battery would never run down, produce an unchanging voltage, and be capable of withstanding environmental extremes of heat and humidity. Real batteries strike a balance between ideal characteristics and practical limitations. For example, the mass of a car battery is about 18 kg or about 1% of the mass of an average car or light-duty truck. This type of battery would supply nearly unlimited energy if used in a smartphone, but would be rejected for this application because of its mass. Thus, no single battery is "best" and batteries are selected for a particular application, keeping things like the mass of the battery, its cost, reliability, and current capacity in mind. There are two basic types of batteries: primary and secondary. A few batteries of each type are described next. Q: What device is an electrochemical cell or series of cells that produces an electric current? Choices: - reactor - magnet - generator - battery A:
(A).
