If you lined up human skin cells side-by-side, how many would fit along the length of the paperclip in the sample problem above?
dimaraw [331]

Hi,

You did not provide the length of paper clip but i searched this exercise to find the length of the paper clip as So, a small paperclip measures 3.0 cm so i will answer your question according to this length.

The size of a human cell is around  30um and the question is asking that how many would fit along the length of the paper clip measuring 3cm.

                              3 cm = 30000 microns

                                          = 30000/30

                                           = 1000 cells.

So, if we line up 1000 human skins cells side-by-side, they would fit along the length of the paperclip.

Note: <em>If the length of paper clip is different in your excercise like 1 cm etc, simply multiply the 1 with 10000 and divide the resultant value with 30, this way you can get cell number for the length of any clip.</em>

Hope it helps!

So, in this study a layer of purple photosynthetic bacteria is using sulfide as an electron source. Sulfide is oxidized by these bacteria, which grow in a layer above sediment from which you have isolated sulfate-reducing bacteria that generate sulfide during anaerobic respiration.

These bacteria's are showing cooperative interaction between each other. Where one species producing a product (sulfate reducing bacteria) that serves as food for other species (photosynthetic bacteria).
