Mutations are changes in the DNA of an organism. Changes caused by mutations can affect the structure and function of different proteins in the body. Three changes caused by mutations are described below. Having two different colored eyes is caused by a mutation that results in increased or decreased pigmentation in one of the eyes. While this mutation affects the coloration of the eye, it does not affect how the eye functions. Cystic fibrosis is caused by the mutation of a protein in the lungs that causes a sticky mucus to build up in the lung tissue. This build up of mucus can make it difficult for a person to breathe. Bone density can be affected by a mutation. This mutation can cause very dense bones that are almost unbreakable. What is true about mutations in organism? 華 ОА. Changes caused by mutations always have positive effects on an organism. ОВ. Changes caused by mutations always have negative effects on an organism. OC. Changes caused by mutations never have an effect on an organism's cells. OD Changes caused by mutations can be harmful, beneficial, or neutral to an organism.​

Suppose you use three different scale to weigh a bag of oranges. one scale says the nag weighs 2.1 lb, and third says it weighs 2.1 lb. the actual weight of the bag of oranges is 2.153 lb. which of the following best decribes these results?

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.
