Saccharomyces cerevisiae is a single-celled yeast that is often used as a model for eukaryotic cells, as it contains all of the important organelles of these cells. The genome of Saccharomyces cerevisiae, commonly known as brewer's yeast, has been completely mapped, making it suitable for genetic engineering experiments. The amount of electric charge on the cell walls plays a significant role in the interaction of these cells with their environment. To determine the electric charge on yeast cells, which is a function of their size, the cells are often placed in electric fields and their motion in these fields is measured. In one such experiment, Saccharomyces cells of mass 3.00 x 109 g placed at rest in a uniform electric field of magnitude 10.0 N/C were measured to be traveling with a speed of 3.60 x 10² μm/s after traversing a distance of 16.0 um along the direction of the electric field. What was the magnitude and sign of the charge on this batch of yeast cells? (a) magnitude (in C) C (b) sign of the charge Opositive RACTICE ANO O negative neutral

Which of the following statements about the "greenbeard" effect is correct? Richard Dawkins first hypothesized the existence of the "greenbeard" allele to explain why we observe some unusual phenotypes, such as green beard. According to the hypothesis, the reason why the greenbeard phenotype is selected for is because the greenbeard individuals would preferentially receive altruistic benefit from non-greenbeard individuals. The reason why the "greenbeard" hypothesis is possible is because when direct fitness and indirect fitness are in conflict, it is always the factors that increase the direct fitness that will triumph over the factors increasing the indirect fitness. The "greenbeard" effect shows that it is possible to evolve altruistic behavior toward individuals who are not genetic kin.
Small birds like that in (Figure 1) can migrate over long distances without feeding, storing energy mostly as fat rather than carbohydrate. Fat is a good form of energy storage because it provides the most energy per unit mass: 1.00 grams of fat provides about 9.40 (food) Calories, compared to 4.20 (food) Calories per 1.00 grams of carbohydrate. Remember that Calories associated with food, which are always capitalized, are not exactly the same as calories used in physics or chemistry, even though they have the same name. More specifically, one food Calorie is equal to 1000 calories of mechanical work or 4184 joules. Therefore, in this problem use the conversion factor 1 Cal = 4184 J. Figure 1 of 1 Part A Consider a bird that flies at an average speed of 10.7 m/s and releases energy from its body fat reserves at an average rate of 3.70 W (this rate represents the power consumption of the bird).

John Snow, an English physician, has observed that disease is becoming more prevalent in a local neighborhood and he wants to know why. He collects information about the local people, including how many family members contracted the disease and where they live. John discovers that the disease is most common in homes located closest to the town’s water pump. John contrives an explanation: that the illness is waterborne and people are contracting the disease from water they retrieve from the town’s water pump. After petitioning the authorities, the handle at the pump is removed. John collects data about disease incidence and finds that occurrence of the disease is greatly reduced. John concludes that the water from the pump was causing the illness. What step(s) of the scientific method is/are missing from Data Table 1? Describe each and propose a way that they might be fulfilled in the scenario?
