Bowerbirds construct elaborate bowers (nests) and decorate them with different colors to attract females. The Satin bowerbird builds a nest between upright sticks, and decorates with bright blue objects, while the MacGregor’s bowerbird builds a tall tunnel of sticks and decorates with bits of white objects. The two populations have almost identical genes, but the birds cannot breed with each other. This is most likely because Select one:

Both species of bird used to breed together until a hurricane randomly killed the some of the birds

The Satin bowerbirds are larger than the McGregor's bower birds

A forest separates the two populations of bird

Their different mating rituals separate the two populations

The fruit of a certain plant is sweet and fleshy. the seeds of this plant have a seed coat that is fairly tough. the seeds germinate better if they are exposed to acid, or scarification. what is the most likely type of dispersal for this seed? water animal wind

All phases of matter may have a fixed mass

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.
