Respuesta: Los caracteres adquiridos no se transmiten genéticamente porque no modifican el ADN de los organismos

Explicación:

Jean-Baptiste Lamarck al igual que Charles Darwin, propuso una teoría sobre la evolución que explicaba cambios en los organismos a través del tiempo. La teoría de Lamarck se enfocaba en condiciones en el ambiente que propiciaban cambios en los organismos. Un ejemplo de esto son las jirafas, que de acurdo a Lamarck tenían cuellos largos debido al esfuerzo continuado para comer hojas de árboles altos. Esto significa que la característica de cuello largo era adquirido por las jirafas durante su vida y según Lamarck se transmitiría a sus descendientes.

Sin embargo, se ha comprobado que los caracteres adquiridos no modifican el ADN de los organismos, por ejemplo las cirugías estéticas no cambian el ADN de una persona y por esta razón no son transmitidos a sus descendientes. Por el contrario, en las poblaciones de organismos ciertas características prevalencen en el tiempo debido a la selección natural. Esto significa que el cuello de las jirafas es el resultado que el cuello largo sea una característica beneficiosa que ha prevalecido debido a la selección natural y no de características adquiridas que son transmitidas a descendientes.

int main(void) {

int sum = 5;  

int i;      

printf("Lift off in T minus\n");

for (i = 0; i < 5; i=i+i) {

   sum = sum - i;  

   printf("sum = %d\n",sum);  

}  

printf("Blast-off",sum);  

return 0;

Technician A says that volatility describes how hard it is for gasoline to evaporate. Technician B says that Reid vapor pressure
Lubov Fominskaja [6]

I’d say both techies are correct.

Volatility, as applied in gasoline, is quantified by the tendency of the liquid to change to vapor at any given temperature (vaporize). This rate of change might be hard or easy, this depends on the temperature or the pressure. Technician B is also correct. RVP is defined and determined experimentally according to the ratio of the vapor volume to the liquid volume at 100 °F.
