(b) Mr and Mrs Smith decided to visit a genetic counsellor who discusses embryo Read the information which they received from the counsellor, Under an anaesthetic five eggs will be removed from Mrs Smith's ovary The eggs will be fertilised in a dish using Mr Smith's sperm colis. The embryos will be grown in the dish until each embryo has about thirty cells. One coll will be removed from each embryo and tested for cystic fibrosis w A suitable embryo will be placed into Mrs. Smith's uterus and she may become pregnant. Any unsuitable embryos will be killed. (1) Suggest why it is helpful to take five eggs from the ovary, rather than just one​

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.
