Nos dias de hoje, com todas as doenças virais, bacterianas que acometem a população e incluindo ainda as infecções hospitalares, quais seriam as medidas profiláticas (prevenção a se tomar tanto no âmbito familiar como as instituições de saúde e de grande circulação de pessoas? Há de se ter mais conscientização por parte da população no que diz respeito aos cuidados com saúde, alimentação saudável, hábitos saudáveis, prática de exercícios físicos, boas horas de sono entre outros?

Translated from Portuguese language:

"Nowadays, with all the viral and bacterial diseases that affect the population and also including hospital infections, what would be the prophylactic measures (prevention to be taken both within the family and health institutions and large circulation of people)?

To have more awareness on the part of the population with regard to health care,Healthy eating, Healthy habits, Physical exercise, Good sleep hours, among others".                                                                                                                                                                                                    

Explanation:

In order to avoid any complications faced by the individuals we have some of the precautions to take care of and for that reason we have to take of our selves, our families and other individuals that are inside the our social circle.As, there are people who should work for the awareness of the situations and they should work for the improvement of the overall situations as well. While, there should be also some fund raising campaign held for providing the sufficient amount of nutrients to the number of individuals.

answer: carbon 14 can only be used to determine the age of the organisms that were once living, and igneous rocks are non living.

explanation:

carbon 14 dating is used to determine the age of the sample by estimating the amount of carbon 14 present in the sample and then comparing it with a reference standard.carbon 14 is a isotope of carbon which is radioactive and unstable. carbon 14 is assimilated by all plants and animals throughout their life from carbon dioxide. however, one the organisms die they stop this assimilation and the carbon 14 content starts to decrease.by knowing how much of carbon 14 is left in an organism after his death, one can estimate the age of the organism. the materials whose age can be estimated by carbon 14 method are the organic compounds. however, some inorganic compounds such as aragonite   shell can also be dated.however, if we consider the igneous rocks it is a non living component which never accumulated carbon 14 in it and thus, we cannot use carbon 14 dating method to estimate its age.
