Natural selection is the process by which biological traits either become more or less apparent within a population. There are certain conditions which are the basis for natural
selection. Which of the following examples best represents the adaptation of a species to its
environment.

A. Some members of a garter snake species are resistant to a toxin produced by one of its food sources and will successfully
reproduce and pass the resistant trait on to their offspring

B. species of crab is living and reproducing successfully near hot hydrothermal vents at the bottom of the Pacific Ocean,
while other crab species are unable to survive there.

C. Male Birds of Paradise inherit brilliant colors which they displayed in elaborate poses or dances in order to catch the
attention of a female mate.

D. Female Loggerhead turtles lay about 100 eggs, which when hatched produce offspring that must make a mad dash to the
ocean before being eaten by predatory sea birds.

98 points 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 forces choose 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.
