Re: Do We Have The Freedom Of Choice?

one could think that it also gives us the feeling of purpose, because we think we're in control and thus makes us try harder and do better in the grand competition that is life. When everything is determined and predictable, why is the delusion needed to make us try harder? Is it possible to gain i...

12.3 shows the "measurement accuracy". Measurement accuracy is the smallest unit on a measuring appliance. It means that the musearing appliance cannot discriminate between 16 and 40.6 (in this measurement).So the exact result may differ between 16 and 40.6. In other words reault=[16,40.6].

The answer I found is that plant cell walls are not permeable to big proteins (more than 30-60 kDa), so they must be passed by plasmodesmata (with 20-40 nm diameter). As a result, every plant cell needs plasmodesmata but animal cells haven't any barrier like cell walls for protein transportation. So...

plasmodesm and gap junction

Both of plasmodesm (in plant cells) and gap juction (in animal cells) pass the micromolecules & ions and connect the cells to each other. Why do all plant cells have plasmodesmata but only some animal cells have gap junctions?
