Tension

Movement water upwards in the xylem is caused by transpirational pull. Water is being pulled from above. Water is therefore, under tension as it moves upwards. It is by no means an active process.

... cell to the other takes seconds, but diffusion from the roots to the top of a giant redwood would take decades or more... In xylem, it is actually tension (negative pressure) that drives long-distance transport... In contrast, bulk flow depends only on pressure..." PLEASE EXPLAIN!!! The stuff ...

... a little more in my book, it emphasized how osmosis/diffusion was NOT the main force for transpirational pull. It talked about negative pressure (tension). My second question is: what role does negative pressure (tension) play in transpirational pull?????????????? My book talked about bulk flow, ...

Question 1, WHICH SET WILL PRODUCE MORE, AND MORE OVERALL FORCE FROM THE SLOW MUSCLE FIBERS, THUS IN TURN MORE TENSION TO THEM. A slow set of slow reps 3/3, using 75% of your 1RM, let us call this 100pounds, 6 repetitions = 36 seconds. You fail faster in the faster rep with the ...

... about converting things you want to measure into things you can measure example--entropy of a stretching polymer as related to temperature, and tension. If you didn't know, the great Michael Jordan said that the reason he became so good at taking jump shots was because the defense wised up to ...
