Dr. brantz wants to use neuroimaging to detect which part of the brain is active when a person is lying. he asks half his participants to tell the truth about an event from their childhood and half to tell a lie about such an event. he will then use to detect brain areas that are active when the participants are lying.

Ответ:
Dr. Brantz wants to test the part of the brain which is active while lying. For this purpose, he will need to make use of the fMRI (functional magnetic resonance imaging) technique. This technique is used for measuring the brain activity by the means of the detecting changes in the blood flow. The neural activation affects the cerebral blood flow, and this change can be noticed using fMRI.
Hence, the answer is 'fMRI'.

Respuesta:
d) los genes están hechos de ADN
Explicación:
Los genes son segmentos definidos de secuencia contenidos en ambas cadenas de ADN los cuales codifican para un ARN mensajero (ARNm) durante el proceso de transcripcion y subsecuentemente son traducidos a proteínas. Estas proteínas son a su vez responsables de las características fenotipícas del individuo como por ejemplo, en este caso, el color de los ojos o la formación de hormona insulina.
Las leyes de Mendel constituyen el fundamento de la genética moderna y nos han permitido entender cómo se transmiten los caracteres hereditarios. Luego de los descubrimientos de Mendel, Boveri y Sutton comprobaron independientemente la veracidad de sus conclusiones y finalmente quedo formulado el concepto de gen como unidad básica de la herencia, asociando de este modo la transferencia de los factores mendelianos (alelos) con la segregación de cromosómica durante la división celular.
