When a person has not taken in suffi cient water they become dehydrated. this may cause a loss of blood pressure, which will trigger the release of antidiuretic hormone (adh) from the hypothalamus and pituitary glands. this hormone signals the kidney to allow reabsorption of water by the blood vessels to bring the blood pressure back to normal conditions.

the correct answer is: b. pantala flavescens, because these organisms would have a high level of genetic variation due to sexual reproduction.  

because involves two organisms (parents) whose genetic material combines, sexual reproduction leads to genetic variation in new generations of offspring. the offspring is an unique organism, with new genome, more protected with the higher ability to adapted. this process is fundamental to evolution.

her next move would be to use agarose gel electrophoresis to separate the dna molecules of varying length and create a dna fingerprint.
