Answer the following question given this paragraph: Magnetic Field Produced by a Current-Carrying Solenoid A solenoid is a long coil of wire (with many turns or loops, as opposed to a flat loop). Because of its shape, the field inside a solenoid can be very uniform, and also very strong. The field just outside the coils is nearly zero. Figure 22.40 shows how the field looks and how its direction is given by RHR-2. Q: What current-carrying long coil of wire acts as a magnet? Choices: - converter - antenna - igniter - solenoid A:
solenoid
Answer the following question given this paragraph: Q: In some species, what has led to the evolution of alternative male mating behavior and morphology? Choices: - distributive selection - similar selection - sexual process - sexual selection A:
sexual selection
Q: Answer the following question given this paragraph: John Romanes, modified by CK-12 Foundation. Wings of bats and birds are analogous structures . Public Domain. Q: Due to similar function, the wings of bats and birds are referred to as what type of structures? Choices: - symmetrical structures - matching structures - Identical structures - analogous structures A:
A: analogous structures
Question: Answer the following question given this paragraph: The kidneys also need constant pressure to filter the blood. When the blood pressure drops too low, the kidneys increase the pressure. One way is by producing angiotensin, a blood vessel-constricting protein. This protein also signals the body to retain sodium and water. Together, the constriction of blood vessels and retention of sodium and water help restore normal blood pressure. Q: What organs need constant pressure to filter the blood? Choices: - lungs - dialysis - arteries - kidneys A:
Answer: kidneys

Answer the following question given this paragraph: Solutions can also become supersaturated , where the amount of solute dissolved exceeds its solubility. Supersaturation most commonly occurs when a saturated solution is slowly cooled. They occur frequently in geological and meteorological processes. Supersaturated systems are unstable, and eventually, the solute will precipitate until a saturated solution is regenerated. We can quantify supersaturation by looking at solubility curves. If the ratio of solute to solvent is above the saturation curve at the given temperature, the solution is supersaturated. If it is on the curve, the solution is saturated, and if it is below the curve, the solution is unsaturated. Q: Solutions can also become supersaturated , where the amount of solute dissolved exceeds what? Choices: - part solubility - its dissolution - its concentration - its solubility A:
(Answer)
its solubility
