Problem: You are given a new situation: Robert is generating waves using an oscilloscope in his high school physics class. As part of the experiment, Robert first has to create waves with a long wavelength, waves that we will call long waves. Afterwards, Robert has to create waves with a short wavelength, waves that we will call short waves. and a hint : Figure B above shows an important relationship between the wavelength and frequency of a wave. The top wave clearly has a shorter wavelength than the second wave. However, if you picture yourself at a stationary point watching these waves pass by, more waves of the first kind would pass by in a given amount of time. Thus the frequency of the first waves is greater than that of the second waves. Wavelength and frequency are therefore inversely related. As the wavelength of a wave increases, its frequency decreases. The equation that relates the two is Please answer this question : Which waves will have a lower frequency?

A: long waves

Problem: You are given a new situation: A sudden climate change hits Alaska and it starts to become warmer. As a result many species of mammals have started to adapt to the warmer climate and now grow less fur. and a hint : Some mutations have a positive effect on the organism in which they occur. They are called beneficial mutations . They lead to new versions of proteins that help organisms adapt to changes in their environment. Beneficial mutations are essential for evolution to occur. They increase an organism's changes of surviving or reproducing, so they are likely to become more common over time. There are several well-known examples of beneficial mutations. Here are just two: Please answer this question : Will the adaptation of growing less fur in a warmer environment increase or decrease the chances of these mammals reproducing?

A: increase

Problem: You are given a new situation: Customers bought two types of electrical ovens, type A and type B. They were all happy at first but type B ovens started to short circuit. and a hint : For example, if a circuit has a potential difference of 100 volts and it is intended for the circuit to contain a 100 ohm resistance, then the wires carrying the current for this circuit will be designed for 1.0 amp. If that 100 ohm resistance is suddenly cut out of the circuit and only 0.10 ohm resistance remains, then the voltage will push 1000 amps of current through the circuit. This current overheats the wires and may damage the circuits or start a fire in the walls or the appliance. There are many possible causes of a short circuit, one possible cause could be something overheating, melting wires, and thereby fusing the circuit closed, bypassing the resistance. Another cause might be something damaging the insulation of a wire, allowing the incoming and grounds wires to touch. In any case, once the resistance is lost, the voltage pushes a huge amount of charge through the wires causing them to overheat. Please answer this question : Which type of oven had more damaged circuits?

A: type B

Problem: You are given a new situation: Two mycologists studied about mushrooms. Bert studied mycorrhizal fungi, while Vince studied saprophytic mushrooms. and a hint : A mycorrhiza (Greek for "fungus roots") is a symbiotic association between a fungus and the roots of a plant. In a mycorrhizal association, the fungus may colonize the roots of a host plant by either growing directly into the root cells, or by growing around the root cells. This association provides the fungus with relatively constant and direct access to glucose, which the plant produces by photosynthesis. The mycelia of the fungi increase the surface area of the plant's root system. The larger surface area improves water and mineral nutrient absorption from the soil. Please answer this question : Which person studied a bit less about the mycelia of the fungi?

A:
Vince
