In 1960’s studies of rats, scientists found that crowding increases the number of attacks among the animals significantly. but in recent experiments in which rhesus monkeys were placed in crowded conditions, it was not such attacks that increased significantly, but rather instances of "coping" behavior, such as submissive gestures, avoidance of dominant individuals, and huddling with relatives. therefore the evidence from rhesus monkeys makes it doubtful that crowding significantly increases aggressive impulses in primates.
which of the following, if true, most seriously weakens the argument?
(a) the rhesus monkeys is the species of monkey that is more prone to fighting
(b) coping behavior was adopted by the crowded monkeys to forestall acts of aggression among them
(c) all the observed forms of coping behavior can be found among rhesus monkeys living in uncrowded conditions
(d) some individual monkeys in the experiment were involved in more attacks than the others
(e) some of the rhesus monkeys in the experiment were subjected to levels of crowding that are unlikely to occur in natural circumstances.

The lineage of pea plants produced round seeds for four generations. the plants that fertilized these pea plants also produced round seeds. however, in the fifth generation, the plant produced to two plants with wrinkled seeds. can that be possible?

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.
