Rough-skinned newts and common garter snakes are in an "evolutionary arms race." In this phenomenon, two species continually evolve adaptations against one another to increase their own chance of survival. Rough-skinned newts produce tetrodotoxin, a type of poison, as a defense mechanism. Most common garter snakes have some resistance to the toxin. In areas where common garter snakes and rough-skinned newts coexist, rough-skinned newts express very high levels of tetrodotoxin, and common garter snakes have evolved a very high degree of resistance to tetrodotoxin. Based on this information, what is the most likely relationship between common garter snakes and rough-skinned newts? A. obligate parasitism B. facultative mutualism C. predator and prey D. commensalism

You will be galileo perform the experiment to determine if objects with different mass fall at the same, or different, rates in the air and in a vacuum. before you conduct your experiment, you need to form a hypothesis. a hypothesis is a prediction of what you think will happen in the experiment. the hypothesis is a statement that describes “if” a certain set of circumstances are present “then” there will be a specific result that will occur.record your hypothesis here: record the results from step one of the experiment (dropping the objects in the air): first trial: second trial: third trial: record the results from step two of the experiment (dropping the objects in a vacuum): first trial: second trial: third trial: did the experiment support your hypothesis? using the data from your experiment, describe why you believe your hypothesis was either proven or disproven.what forces were acting on the objects dropped in the air? what force was acting on the objects dropped in the vacuum? part two: comparing forceschoose two forces and compare and contrast these forces. you must provide two ways that they are alike and two ways that they are different. you may make a list, write in paragraph form, or make a chart.choose two forces and compare and contrast these forces. these must be different forces than used in the prior question. provide two ways that they are similar and two ways that they are different. you may make a list, write it out, or make a chart.
