1) An increased rate of evaporation due to a temperature rise will hasten the loss of water. 2) Decreased relativehumidity outside the leaf will increase the water potential gradient. Relative humidity. Drier surroundings give a steeper water potential gradient, and so increase the rate of transpiration. Wind.

Vaginal lubrication is always present, but production increases significantly near ovulation and during sexual arousal in anticipation of sexual intercourse. Vaginal dryness is the condition in which this lubrication is insufficient, and sometimes artificial ...

Evolutionary history of plants. A late Silurian sporangium, artificially colored. Green: A spore tetrad. Blue: A spore bearing a trilete mark – the Y -shaped scar. The spores are about 30–35 μm across. The evolution of plants has resulted in a wide range of complexity, from the earliest algal mats of unicellular archaeplastids evolved ...
