Answer the following question given this paragraph: Meters, such as those in analog fuel gauges on a car, are another common application of magnetic torque on a current-carrying loop. Figure 22.37 shows that a meter is very similar in construction to a motor. The meter in the figure has its magnets shaped to limit the effect of by making B perpendicular to the loop over a large angular range. Thus the torque is proportional to I and not. Q: Meters, such as those in analog fuel gauges on a car, are a common application of magnetic torque on a current-carrying what? Choices: - circuit - dial - arc - loop A:
loop

Answer the following question given this paragraph: Some molecules, such as proteins, are too large to pass through the plasma membrane, regardless of their concentration inside and outside the cell. Very large molecules cross the plasma membrane with a different sort of help, called vesicle transport . Vesicle transport requires energy, so it is also a form of active transport. There are two types of vesicle transport: endocytosis and exocytosis. Both types are shown in Figure below and described below. Q: What type of transport is vesicle transport considered to be? Choices: - passive transport - intercellular transport - catalyst - active transport A:
(Answer)
active transport
Ques: Answer the following question given this paragraph: The embryo, which begins as a flat sheet of cells, begins to acquire a cylindrical shape through the process of embryonic folding (Figure 28.14). The embryo folds laterally and again at either end, forming a C-shape with distinct head and tail ends. The embryo envelops a portion of the yolk sac, which protrudes with the umbilical cord from what will become the abdomen. The folding essentially creates a tube, called the primitive gut, that is lined by the endoderm. The amniotic sac, which was sitting on top of the flat embryo, envelops the embryo as it folds. Q: What sac, which was sitting on top of the flat embryo, envelops the embryo as it folds? Choices: - uterus - umbilical sac - epithelial sac - amniotic sac A:
Ans: amniotic sac

Answer the following question given this paragraph: In the first beaker, distilled water does not conduct a current because water is a molecular compound. In the second beaker, solid sodium chloride also does not conduct a current. Despite being ionic and thus composed of charges particles, the solid crystal lattice does not allow the ions to move between the electrodes. Mobile charged particles are required for the circuit to be complete and the light bulb to light up. In the third beaker, the NaCl has been dissolved into the distilled water. Now the crystal lattice has been broken apart and the individual positive and negative ions can move. Cations move to one electrode, while anions move to the other, allowing electricity to flow (see Figure below ). Melting an ionic compound also frees the ions to conduct a current. Ionic compounds conduct an electric current when melted or dissolved in water. Q: In the first beaker, distilled water does not conduct a current because water is a what? Choices: - pure element - solute - magnetic compound - molecular compound A:
(A).
molecular compound
Ques:Answer the following question given this paragraph: The two adrenal glands are glands located just above the kidneys. Each adrenal gland has an outer layer (cortex) and inner layer (medulla) that secrete different hormones. The hormone adrenaline is secreted by the inner layer. It prepares the body to respond to emergencies. For example, it increases the amount of oxygen and glucose going to the muscles. Q: The two adrenal glands are glands located just above the what? Choices: - intestines - lungs - esophagus - kidneys A:

Ans:kidneys
Answer the following question given this paragraph: Recall that ecology is the study of how living organisms interact with each other and with their environment. But how do organisms interact with each other? Organisms interact with each other through various mechanisms, one of which is competition. Competition occurs when organisms strive for limited resources. Competition can be for food, water, light, or space. This interaction can be between organisms of the same species (intraspecific) or between organisms of different species (interspecific). Q: What is the study of how living organisms interact with each other and with their environment? Choices: - botany - zoology - genetics - ecology A:
ecology
