sorry, i have been asked for 10 questions, but you only answered four of them.

Well, you don't have a very good record of accepting any answers. I will send this to the moderators for their help in closing this question.

Thanks. I have been posted this following question for 5 days already, but no one answer for me, can you answer it?   don't have exactly right answer, just your experience.

--------------------------------------------------------------------------------

What is the optimal temperature for invertase activity? Is this what you expected? Would invertase isolated from any two organisms (for example, yeast invertase vs. invertase from the small intestine of humans) show the same temperature optimum? Why or why not? Explain your answers. Explain why temperatures lower or higher than the optimum cause decreases in invertase activity. What is happening to the enzyme to produce these decreases in activity? Carefully examine the curve for VO vs. temperature. Is the slope of the line on both sides of the curve the same or different? If the slope of the line to the left of maximum velocity is different from the slope of the line to the right of maximum velocity, explain why this is. What is responsible for these differences in enzyme kinetics? If you were to carry out these temperature experiments at a higher or lower [S], what effect would [S] have on the temperature optimum for invertase? Formulate a hypothesis and then test your hypothesis.

I'm sorry but that would be another question. It would require a lot of time to put all that together to give you an answer. That is probably why you haven't received a reply. It is a question that all by itself is worth more than $30.
Customer: replied 6 years ago.
no problem, i will pay for it. but can you let me know if you can answer it? thanks.
Expert:  A. Schuyler, NP replied 6 years ago.
Sorry, that's not my field. I would suggest you post it as a separate question.
Customer: replied 6 years ago.
ok, thanks. but you mean you can't answer this question?
Expert:  A. Schuyler, NP replied 6 years ago.

I mean that it's not something I can do right now. I have to get ready for work, for one thing. We have a couple of new young doctors online tonight who should find this right up their alley.

 

Customer: replied 6 years ago.
should I post in here or I have to post on "answer my question?"

Thanks.

Expert:  A. Schuyler, NP replied 6 years ago.
You should go back to the beginning and ask a whole new question. Tucked onto the end of this one, they probably won't see it - especially since I've already answered the first two for you. When a new question comes up (especially one valued at $30) they should jump right on it.
Customer: replied 6 years ago.
Thanks.

i already posted my question online, can you look at it? thanks.
Expert:  A. Schuyler, NP replied 6 years ago.
It looks good! Good luck.
Customer: replied 6 years ago.
can you answer my questions?
Customer: replied 6 years ago.
With the exception of identical twins, siblings who have the same two biological parents are likely to look similar, but not identical, to each other because they have (Points: 2)
        identical chromosomes but not identical genes.
        a similar but not identical combination of genes.
        the same combination of traits but different genes.
        identical genes but different chromosomes.
        only a 20% chance of sharing the same combination of genes.
Customer: replied 6 years ago.
are you sure the answer is right for this question?

Which one of the following does not occur during mitotic anaphase?
        The centromeres of each chromosome divide.
        Sister chromatids separate.
        Daughter chromosomes begin to move toward opposite poles of the cell.
        The chromatid DNA replicates.
        All of the choices occur during mitotic anaphase.
your answer is The chromatid DNA replicates.
Expert:  A. Schuyler, NP replied 6 years ago.
Yes, I'm sure that chromatid DNA replication doesn't happen during anaphase.

do you know why takes so long for my questions posted online few days ago? can you check? thanks.

do you know why take so long for somebody to answer my question that i was posted online few days already? thanks.
Expert:  A. Schuyler, NP replied 6 years ago.

The way JA works is that the customer asks the questions and assigns a value to them. If an expert sees the question and thinks they can answer it for the assigned price, they do so. Sometimes a question will be too technical for the experts who see it. Sometimes it will be too involved, or too long, and no expert wants to bother answering it for the dollar value assigned. You would be amazed at the people who post a question wanting a 500-word research paper in APA format on some arcane health subject and assign a value of $20 to it. That kind of question usually gets answered better in the homework forum. For most of us on the health forum, it has been years and years since basic science, and we all prefer to answer questions dealing with what we do everyday when we aren't online with JA - which the practice of medicine, pharmacy, nursing, etc.
