The length of a vessel is directly proportional to its resistance: the longer the veessel, the greater the resistance and the lower the flow. As with blood volume, this makes intuitive sense, since the increased surface area of the vessel will impede the flow of blood.
Answer:ways Water enters the atmosphere evaporation, transpiration, excretion and sublimation:
Explanation:
Transpiration is the loss of water from plants (via their leaves).
Sublimation is when ice or snow transforms directly into water vapour without going through a liquid phase (i.e. they do not melt).
Animals excrete water by respiration and by passing urine.
Evaporation is a type of vaporization that occurs on the surface of a liquid as it changes into the gas phase.
