First, there were two independent clinical psychologists who were present or on call 24 hours a day. They had the power to intervene and to remove anyone from the study if they thought they were in distress.
Second, we had paramedics and security guards on hand and ready to intervene at a moment’s notice if anything untoward happened in the study.
Third, the study was constantly monitored by members of a five-person independent ethics panel. This was chaired by a Member of Parliament and also included members of the Holocaust Educational Trust, the Howard League for Penal Reform, the BBC’s Independent Editorial Policy Unit and a senior academic psychologist. This committee had the power to change the way the study as a whole was run and to terminate it if they had ethical concerns.

The gene expression of the organism may be affected by the environment. This includes the outside ecosphere where the entire creature and organism are situated or progresses, and also as the organism's interior ecosphere, these consist of the aspects of metabolism and hormones. Even though the structure of genes is unaffected by the environment, the gene expression (how the genes work) will be affected. Factors in the environment like drugs, foods, and toxins may result in some epigenetic changes by changing how the DNA bind by the molecules and the structure change of the proteins that the DNA wraps.

Answer:
Desertificación.
Explicación:
La quema de combustibles en industrias y vehículos produce gas dióxido de carbono en una gran cantidad que contamina el aire. Este gas de dióxido de carbono es un gas de efecto invernadero que se acumula en la atmósfera y bloquea la radiación solar que va al espacio después de la refección, lo que provoca un aumento de la temperatura de la tierra y una condición de sequía que conduce a la desertificación. Debido a esta desertificación, la vegetación se elimina por falta de agua suficiente.
