Wow, you make me stay here for nearly an hour to wait for you to answer a question. Thanks. By the way, don't say how you didn't know the answer, you could have informed me of that 50min earlier.

Let me explain how the Jiskha Homework Help site works.

First, as you know, all tutors are volunteers. We donate our time and expertise when we have time.

I have no idea which microscope to use to look at a piece of moldy bread -- but someone may be able to help you.

Have patience, child.

YOU COULD HAVE INFORMED ME OF THAT AN HOUR EARLIER!

We did -- at the top of the page.

"More than 200 tutors volunteer their time to help over 4,000 students with homework everyday. Students receive answers from teachers in various school subjects including math, science, social studies and more."

Moreover we do not have the slightest idea what microscopes you might have in your school.

....and you answered the question about how many cars and trucks incorrectly thereby confusing some other poor student.

I apologize for any inconvenience caused by the delay in answering your question. As an AI language model, I strive to provide accurate and helpful responses. However, there are instances when I may not have the specific information you are looking for or when the question requires more time to generate a comprehensive answer. In such cases, it is helpful to provide as much context and detail as possible in the initial question to ensure a more prompt and accurate response. Your feedback is valued, and I will take it into consideration to improve my performance. Thank you for your understanding.
