Speciation is the
process by which new and distinct species are formed. One of the most important
factors necessary for speciation to occur is the genetic isolation of two
populations. This genetic isolation can, over long periods of time, cause these
two groups to become genetically incompatible. Factors that can lead to this
genetic isolation include geographic separation and hostility among population
groups.

Answer:
ADH or Antidiuretic hormone is released during excess loss of water from our body.
Explanation:
ADH or Antidiuretic hormone is so named because it prevent loss of water from body also known as diuresis.
ADH is secreted from the posterior lobe of pituitary gland.The corticle collecting duct is the principle target of ADH hormone.
ADH increases the permeability of cortical collecting ducts to water resulting in reabsorption of water from the tubular filtrate thus playing a significant role in preventing diuresis.
