Q: When alternating primary current passes through coil p, it does what to the iron core? Read this paragraph and choose the correct option from the provided answers: As you can see in Figure above , a transformer consists of two wire coils wrapped around an iron core. When alternating primary current passes through coil P, it magnetizes the iron core. Because the current is alternating, the magnetic field of the iron core keeps reversing. This changing magnetic field induces alternating current in coil S, which is part of another circuit. In Figure above , coil P and coil S have the same number of turns of wire. In this case, the voltages of the primary and secondary currents are the same. However, when the two coils have different numbers of turns, the voltage of the secondary current is different than the voltage of the primary current. Both cases are illustrated in Figure below . Choices: - electrilizes it - creates it - heats it - magnetizes it A:
(A).
magnetizes it

Q: What happens when more glucose is present than the proteins can handle, in the body? Read this paragraph and choose the correct option from the provided answers: An example of this process occurs in the kidney. Glucose, water, salts, ions, and amino acids needed by the body are filtered in one part of the kidney. This filtrate, which includes glucose, is then reabsorbed in another part of the kidney. Because there are only a finite number of carrier proteins for glucose, if more glucose is present than the proteins can handle, the excess is not transported and it is excreted from the body in the urine. In a diabetic individual, this is described as "spilling glucose into the urine. " A different group of carrier proteins called glucose transport proteins, or GLUTs, are involved in transporting glucose and other hexose sugars through plasma membranes within the body. Channel and carrier proteins transport material at different rates. Channel proteins transport much more quickly than do carrier proteins. Channel proteins facilitate diffusion at a rate of tens of millions of molecules per second, whereas carrier proteins work at a rate of a thousand to a million molecules per second. Choices: - cultured as urine - metamorphosed as urine - forms urine - excreted as urine A:
(A).
excreted as urine

Q: What is the study of forces in equilibrium? Read this paragraph and choose the correct option from the provided answers: Statics is the study of forces in equilibrium. Two conditions must be met to achieve equilibrium, which is defined to be motion without linear or rotational acceleration. The first condition necessary to achieve equilibrium is that the net external force on the system must be zero, so that net F = 0 . Choices: - law of inertia - genomics - law of conservation - statics A:
(A).
statics
