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 .

Answer: 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? A:
OPTIONS:
- lungs
- heart
- liver
- kidneys
Answer: kidneys

input with options: 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? A:
OPTIONS:
- brain signals
- hormone levels
- nutrient levels
- metabolic processes
output: metabolic processes

Q: Answer the following question given this paragraph: Magnetic Moments of Molecules and Ions Experimental evidence of magnetic measurements supports the theory of high- and low-spin complexes. Remember that molecules such as O2 that contain unpaired electrons are paramagnetic. Paramagnetic substances are attracted to magnetic fields. Many transition metal complexes have unpaired electrons and hence are paramagnetic. Molecules such as N2 and ions such as Na+ and [Fe(CN)6]4 that contain no unpaired electrons are diamagnetic. Diamagnetic substances have a slight tendency to be repelled by magnetic fields. When an electron in an atom or ion is unpaired, the magnetic moment due to its spin makes the entire atom or ion paramagnetic. The size of the magnetic moment of a system containing unpaired electrons is related directly to the number of such electrons: the greater the number of unpaired electrons, the larger the magnetic moment. Therefore, the observed magnetic moment is used to determine the number of unpaired electrons present. The measured magnetic moment of low-spin d6 [Fe(CN)6]4 confirms that iron is diamagnetic, whereas high-spin d6 [Fe(H2O)6]2+ has four unpaired electrons with a magnetic moment that confirms this arrangement. Q: As the number of unpaired electrons increases, what happens to the magnetic moment? A:

OPTIONS:
- is destroyed
- remains the same
- gets smaller
- gets larger

A: gets larger

input: OPTIONS:
- neither
- positive
- both
- negative Now, answer this question: Answer the following question given this paragraph: Q: Does climate change have a positive or negative effect on reproductive success? A:
A:
output: negative

Question: Answer the following question given this paragraph: The solubility of a substance is the amount of that substance that is required to form a saturated solution in a given amount of solvent at a specified temperature. Solubility is often measured as the grams of solute per 100 g of solvent. The solubility of sodium chloride in water is 36.0 g per 100 g water at 20C. The temperature must be specified because solubility varies with temperature. For gases, the pressure must also be specified. Solubility is specific for a particular solvent. We will consider solubility of material in water as solvent. Q: What term means the amount of a substance required to form a saturated solution in a given amount of solvent at a specified temperature? A:
OPTIONS:
- viscosity
- concentration
- turbidity
- solubility
Answer:
solubility
