Dehydration is a condition in which the rate at which the body looses t fluids is higher than the rate at which it takes fluids in.
It is caused by diarrhoea( watery stools )
2.Excessive sweating.
3 vomiting continusly.
4. No access to water intake
5.Polyuria(excessive urination)
6.Fever leading to hyperthermia.
The kidney is the main organ where the effect of dehydration is managed . As a result of increase in the solute potential of the blood,;the hypothalamus secrets ADH hormones which stimulates the Aquaporins(transmembrane proteins in the collecting duct and the distal convoluted tubules) to open .Therefore water moves in by osmosis to reduce the higher solute potential of the blood. Therfore low volume,high concentrated urine is produced.
This homeostatic function of the kidney ensures balanced in the electrolyte fluids of the body to manage dehydration,before medical intervention.

Brodt and Zimbardo found that shy women who were bombarded with loud noise and told that it would leave them with a pounding heart were subsequently no longer so shy when interacting with a handsome male.
a) with a pounding heart; no longer so shy

Shy is an emotion expressing nervousness, being reserved and timidity when communicating or being with some people. Shyness is generally observed in the person who has low self-confidence and inferiority complex.

These scientists also found that when woman is interacting with the handsome male they will never feel shy.
This is an example of microevolution.
Microevolution represents a small change in the genetic structure of the population. These changes manifest through the change in the allele frequencies of genes like in the case of dung beetles.
The causes of microevolution are evolutionary mechanisms, natural selection, genetic drift, mutations and gene flow.
