Answer the following question given this paragraph: Specialized structures for reproduction: One example is a fruiting body. Just like a fruit is involved in the reproduction of a fruiting plant, a fruiting body is involved in the reproduction of a fungus. A mushroom is a fruiting body , which is the part of the fungus that produces spores ( Figure below ). The spores are the basic reproductive units of fungi. The mycelium remains hidden until it develops one or more fruiting bodies. Q: Spores are the basic reproductive units of what organism? Choices: - mushrooms - yeast - tropical plants - fungi A:
fungi
Answer the following question given this paragraph: What if you were to drop a bowling ball and a soccer ball at the same time from the same distance above the ground? The bowling ball has greater mass than the basketball, so the pull of gravity on it is greater. Would it fall to the ground faster? No, the bowling ball and basketball would reach the ground at the same time. The reason? The more massive bowling ball is also harder to move because of its greater mass, so it ends up moving at the same acceleration as the soccer ball. This is true of all falling objects. They all accelerate at the same rate due to gravity, unless air resistance affects one object more than another. For example, a falling leaf is slowed down by air resistance more than a falling acorn because of the leaf's greater surface area. You can simulate the effect of air resistance on acceleration due to gravity by doing the interactive animation at this URL: http://www. science-animations. com/support-files/freefall. swf. Q: In the absence of air resistance, all falling objects accelerate at the same rate due to what force? Choices: - velocity - weight - motion - gravity A:
gravity
Q: Answer the following question given this paragraph: All electric circuits have at least two parts: a voltage source and a conductor. They may have other parts as well, such as light bulbs and switches, as in the simple circuit seen in the Figure below . To see an animation of a circuit like this one, go to: http://www. rkm. com. au/animations/animation-electrical-circuit. html. Q: A voltage source and a conductor are common to all what? Choices: - magnets - thermometers - cooling circuits - electric circuits A:
A: electric circuits
Question: Answer the following question given this paragraph: blood containing the metabolic wastes from cells. All the blood in the human body is filtered about 60 times a day by the kidneys. The nephrons remove wastes, concentrate them, and form urine that is collected in the bladder. Internally, the kidney has three regionsan outer cortex, a medulla in the middle, and the renal pelvis, which is the expanded end of the ureter. The renal cortex contains the nephronsthe functional unit of the kidney. The renal pelvis collects the urine and leads to the ureter on the outside of the kidney. The ureters are urine-bearing tubes that exit the kidney and empty into the urinary bladder. Q: All the blood in the human body is filtered about 60 times a day by what? Choices: - lungs - heart - liver - kidneys A:
Answer: kidneys

Answer the following question given this paragraph: Hormonal Regulation of Metabolism Catabolic and anabolic hormones in the body help regulate metabolic processes. Catabolic hormones stimulate the breakdown of molecules and the production of energy. These include cortisol, glucagon, adrenaline/epinephrine, and cytokines. All of these hormones are mobilized at specific times to meet the needs of the body. Anabolic hormones are required for the synthesis of molecules and include growth hormone, insulin-like growth factor, insulin, testosterone, and estrogen. Table 24.1 summarizes the function of each of the catabolic hormones and Table 24.2 summarizes the functions of the anabolic hormones. Q: Catabolic and anabolic hormones in the body help regulate these? Choices: - brain signals - hormone levels - nutrient levels - metabolic processes A:
**Answer**
metabolic processes
(Q).
Answer the following question given this paragraph: Water is a common chemical substance on planet Earth. In fact, Earth is sometimes called the "water planet" because almost 75% of its surface is covered with water. If you look at Figure below , you will see where Earth's water is found. The term water generally refers to its liquid state, and water is a liquid over a wide range of temperatures on Earth. However, water also occurs on Earth as a solid (ice) and as a gas (water vapor). Q: What is a common chemical substance on planet earth? Choices: - oxygen - nitrogen - hydrogen - water A:
(A).
water
