美国生物学报告代写:扩散和渗透

这个实验室是为了了解扩散和渗透是如何工作的。接收到的数据有时是一致的。A、D部分实验结果与计算结果一致,B、C部分一致性较差。这是因为B和C部分在比较质量变化百分比时,数字是变化的。质量的差被改变了,因为它可能会误导,变成百分数,消除了任何尺寸因子,然后比较结果。不过,在比较两个百分比时,有些差异太大,以至于无法获得准确的数据。一些可能改变结果的可能性包括透析袋的末端没有绑好,输液不准确,透析袋外部没有彻底清洗,以及计算和测量不正确。我们可以对这个实验室进行修改,在处理这些溶液的时候戴上手套,这样可以得到更加一致的数据,所以当一个人完成了透析袋的浇注和捆扎工作后,可以摘下手套,减少溶液在袋子外面的可能性。更准确、准确地测量溶液,并可安排袋头的松紧度和绑扎方法相同。通过对实验室的这些改变,获得更一致数据的可能性更高。

美国生物学报告代写:扩散和渗透

This lab was to understand how diffusion and osmosis worked. The data that was received was consistent at some times. For part A and D of the lab, the results and calculations were consistent, but part B and C showed little consistency. That is because part B and C when comparing the percent change in mass with others, the numbers varied. The difference of the mass was changed, for it maybe misleading, into percentage, there eliminating any size factor and to compare the results. Though when comparing the percents with one another, some of the difference was too great to receive any accurate data. Some possibilities that may have altered the outcome of the results include the ends of the dialysis bags not being tied correctly, the inaccuracy of pouring the solutions, not a thorough cleaning of the outside of the dialysis bag and incorrect calculation and measurements. This lab can be modified to get a more consistent data by wearing gloves when working with the solutions, so when one is done pouring and tying the dialysis bag, gloves can be removed to reduce any chance of the solution being on the outside of the bag. A more accurate and precise measurement of the solution and the tightness and method of tying the ends of the bags can be arranged to be the same. With those alterations to the lab, the chance of a more consistent data is higher.
