Me on these 1. read the excerpt from a reading passage titled "matter and energy: evaporation and condensation." condensation an example of condensation can be seen when drops of water form on the outside of a glass of ice water. the drops seem to appear from nowhere, but they actually form from water vapor in the air. the dew that forms on grass overnight is another example of condensation. condensation happens when molecules in a gas cool down. as the molecules lose heat, they lose energy. as a result they slow down. they move closer to other gas molecules. finally these molecules collect together to form a liquid. (source: encyclopaedia britannica, adapted by newsela staff, 06/02/2017) describe the process of how dew forms on a blade of grass. question 10 options: dew forms on grass when water vapor forms when molecules cool and separate. dew forms on grass when water vapor forms when liquid cools and becomes a gas. dew forms on grass as water vapor warms up on blades of grass overnight. dew forms on grass when water vapor forms when molecules cool and join together. 2. read the following lab report from a chemistry experiment. determine their hypothesis. we wanted to know how temperature affected the volume of a gas. we investigated this by filling a balloon with air and heating and cooling it, comparing the circumference of the balloon before and after. our results showed the balloon got bigger when heated and smaller when cooled. these results support our hypothesis. question 12 options: gases contract when heated and expand when cooled. the gas temperature will not impact the circumference of the balloon. gases expand when heated and contract when cooled. volume and temperature are not related.

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.
