Scientists collected samples of each group of flies. They placed some of the flies, together, in flasks with both apples and hawthorn fruit. Other flasks contained either apple-eating flies or hawthorne-eating flies. Only the flies in the single fruit flasks mated and
produced offspring. To confirm their results, the scientists isolated flies from each group and put one of each into a flask with food.
Eventually the flies died
without mating. What conclusions apply to this situation? All BUT ONE could apply.
A)One fly species became two species via natural selection.
B)By eating different fruits, the flies changed genetically.
C)Over time, each group evolved different traits that aided in their survival.
D)Living in the ground and emerging a different times was a kind of
geographic isolation

Color blindedness is a sex-linked trait. if we could see the pedigree chart for several more generations of the family illustrated here, we would expect a) more males to be color blind. eliminate b) more females to be color blind. c) no females to ever be color blind. d) an equal number of males and females that are color blind.

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.
