Can a neutral stimulus also be a conditioned response? A neutral stimulus is a stimulus which initially produces no specific response other than focusing attention. In classical conditioning, when used together with an unconditioned stimulus, the neutral stimulus becomes a conditioned stimulus. What are some examples of neutral stimulus? A Neutral Stimulus is a stimulus […]

What does a resistor do in a circuit? A resistor is a passive two-terminal electrical component that implements electrical resistance as a circuit element. In electronic circuits, resistors are used to reduce current flow, adjust signal levels, to divide voltages, bias active elements, and terminate transmission lines, among other uses. Why do we measure voltage […]

What is meant by heat of vaporization? The heat of vaporization is defined as the amount of heat needed to turn 1 g of a liquid into a vapor, without a rise in the temperature of the liquid. The units are cal/gram and values for the heat of vaporization of water at different temperatures are […]

What disease affects the red blood cell? hemolytic anemia. nutritional anemias (e.g. iron deficiency anemia, and folate deficiency) disorders of heme production (e.g. sideroblastic anemia) polycythemia (too many red blood cells) What is the most common red blood cell disorder? Sickle cell anemia is the most common type of inherited blood disorders. Healthy blood cells […]

What are two examples of a behavioral adaptation? Behavioral Adaptation: Actions animals take to survive in their environments. Examples are hibernation, migration, and instincts. Example: Birds fly south in the winter because they can find more food. What is the difference between a physical and behavioral adaptation provide examples? If an animal changes the way […]

What is known as right hand thumb rule? The right-hand rule imposes the following procedure for choosing one of the two directions. With the thumb, index, and middle fingers at right angles to each other (with the index finger pointed straight), the middle finger points in the direction of c when the thumb represents a […]

Do people fall on a rope in a tug of war each pull with a 304sh What is the net force? The object will move if its at rest and it will stop if its in motion. When the two people are pulling the rope with opposite direction, therefore the net force is equal to […]

Can 3 forces have a vector sum of zero? If the net force is equal to zero, the object is said to be in equilibrium. When the aircraft is in equilibrium, the vector sum of these three forces is equal to zero. Because it is a vector sum, there are two component equations, one vertical […]

Can I drill above a plug socket? Don’t drill directly above or below light switches and plug sockets. Invest in a stud finder/metal detector (as mentioned above) that will detect wires and pipes. If you do mistakenly drill into a water pipe, think of the little boy with his thumb in the dyke and LEAVE […]

What happens when you mix oxygen and magnesium? When magnesium reacts with oxygen, it produces light bright enough to blind you temporarily. Magnesium burns so bright because the reaction releases a lot of heat. As a result of this exothermic reaction, magnesium gives two electrons to oxygen, forming powdery magnesium oxide (MgO). What happens when […]
