Describe how adh secretion maintains plasma osmolarity levels during dehydration and water loading

Antidiuretic hormone (ADH) acts on the vascular system and the urinary system to regulate solute-water content in the body. During dehydration, secreted by the posterior pituitary gland, the hormone promotes reabsorption of water from urine in the renal tubules hence decreasing plasma osmolarity.

ans.

dna fingerprinting is defined as a process that determines the dna characteristics of an individual. these dna characteristics are unique among individuals as their fingerprints, so it is known as dna fingerprinting.

steps of dna fingerprinting includes extraction of dna from sample, amplification of dna, restriction digestion of amplified dna, and then analysis of dna by gel electrophoresis, respectively.

thus, the next step performed by the scientist is 'to cut the amplified dna (obtained by polymerase chain reaction) by restriction enzymes that cleave the dna into fragments and their analysis.'
