Biology essay on cell growth please help.

  1. Feb 7, 2008 #1
    I seriously need all the help I can get because I dont understand these last two questions of this essay, I got everything else figured out and done except for the two at the bottom. Details;
    "A scientist designed the following experiment to test the limits of cell population growth. Cells were grown in six flasks under different temperature conditions. Each flask contained a nutrient broth of the same concentration. The table below shows the data obtained from the experiment. Study the table and answer the questions that follow in a well devolped essay."

    Flask 1: Temp: 0 Vol of nutri: 500 No of cells day 1: 1.0 Day 2: 1.0 Day 3: 1.0
    Flask 2: Temp: 20 Vol of nutri: 500 No of cells day 1: 1.0 Day 2: 1.2 Day 3: 1.2
    Flask 3: Temp: 30 Vol of nutri: 1000 No of cells day 1: 1.0 Day 2: 2.6 Day 3: 3.2
    Flask 4: Temp: 40 Vol of nutri: 500 No of cells day 1: 1.0 Day 2: 2.2 Day 3: 2.2
    Flask 5: Temp: 50 Vol of nutri: 500 No of cells day 1: 1.0 Day 2: 2.0 Day 3: 2.0
    Flask 6: Temp: 60 Vol of nutri: 500 No of cells day 1: 1.0 Day 2: 1.4 Day 3: 1.4

    Two questions I dont get;
    D. Based on the data, what generalization can you make concerning the growth of a population of cells overtime? Exclude results from the flask with the faulty data.

    E. Develop a hypothesis to account for the generalization you made in answer D.

    please and thank you everybody.

    You need to show some of your own effort before we can help you. Perhaps a brief summary of the first few questions will help provide some context as well. For example, in question D, they say to exclude the flask with faulty data...which flask is that, and how did you determine the data were faulty?

    The faulty data is flask 3.. but, I cant even go into detail on those questions because I dont understand them. I'm not asking for answers, or for anyone else to do my work.. just for a little bit of a detailed explanation on what I'm supposed to do.

    Okay, D is asking you to look for a pattern in the cell growth and describe it. If you look at every flask other than flask 3, what happens over each of the three days? Do you see a pattern? Describe that pattern.

    For E, if you figure out the pattern they're asking about in D, you then are being asked to explain why you think that pattern is happening (generate an hypothesis). In this case, looking at what's different about flask 3 might give you a clue.
