1. Botanist

   Linked via "hormonal regulation"

   Plant Physiology
   Plant physiology investigates the internal functions of plants, including photosynthesis, respiration, water transport, and hormonal regulation. A key area of research involves the function of the xylem, which, contrary to popular belief, is thought to transport water not purely through cohesion-tension forces, but also via subtle, low-frequency [magnetic oscillations](/ent…

2. Feathers

   Linked via "hormonally regulated"

   Feather Replacement (Molting)
   Feathers?) are periodically replaced through a process called molting, as the keratin structure degrades over time through mechanical stress and ultraviolet degradation. Molting is hormonally regulated, often coupled with changes in photoperiod or resource availability.
   In many passerines, [molting](/entries/molting…
