Sasha is testing the prototype of his lever design. He is using the design to see how changing the size of a block (fulcrum) changes the height to which a stone can be raised by the lever. Sasha's prototype is shown in the picture. Note that the same stone is used in all the tests. Before Sasha can begin his experiment, he must design a table to record his data. He has already made part of the table. What kind of data should go in the bottom row of Sasha's table? A. the mass of the stone after the measurement with each block B. the masses of the fulcrum blocks used in the tests C. the procedure for how Sasha fastened the stone to the ruler using a rubber band D. the height to which the stone is raised using the different sizes of blocks the correct answer is D

Mike was adopted, and his biological family history is unknown. although he is healthy, he would like some understanding of his genetic makeup, including potential health risks and genes that he could pass on to his children. mike has heard about commercial laboratories that can compare segments of your dna to those of people with common hereditary diseases in order to give you some idea of how susceptible you are to the diseases. the results of these types of tests are highly inconclusive. if mike's dna showed that he shares similarities in a segment of dna with people who have a given disease, his chances of developing that disease or passing it on to his children may be slightly elevated, but they are not 100 percent. these tests can cost more than $2,500 and are not covered by many insurance companies. do you think that mike should undergo the genetic tests? explain your answer. what are the potential pros and cons of having such tests done? describe how the availability of these genetic tests might affect the frequency of genetic diseases in individuals and populations.
