Experiments in environmental toxicology can sometimes be manipulative experiments in which the researcher actively chooses and m

anipulates the independent variable. in hunt's study, for example, dosages of bpa were manipulated and the effects were measured. in manipulative studies, the researcher controls all the other variables in the experiment, so any health effects observed in the test subjects can be attributed to differences in the independent variable.

<u>The answer is true.</u>


In a manipulative field experiment, the specialist first adjusts levels of the predictor variable (or factor), and afterward estimates how at least one factors of intrigue react to these modifications. These outcomes are then used to test theories of circumstances and end results. For instance, on the off chance that we are occupied with testing the speculation that reptile predation controls creepy crawly thickness on little Caribbean islands, we could change the thickness of reptiles in a progression of fenced in areas and measure the subsequent thickness of arachnids (e.g., Spiller and Schoener 1998).

Answer:

Dr. Ingram conducted an C. experimental study.

Explanation:

An experimental study is that in which the variables are in direct control of the researcher. He/she is in control of <em>changing or adjusting</em> them in order to reach an outcome.

Dr. Ingram <em>varied the imageability of items </em>on a list to measure the participants' recalling abilities. He is conducting an experimental study.

Let's see why the other options are not valid in this case:

  • A correlational study tries to find correlations between 2 or more variables.
  • In a naturalistic study the researcher observes a certain phenomenon.
  • An observational study just centers on observing, there is no manipulation of variables.

According to the U.S. Army, how does alQaeda use the Internet? ​
Dmitry [639]

Answer:

El Grupo de Trabajo sobre medidas para hacer frente al uso de Internet con fines

terroristas, del Equipo Especial sobre la Ejecución de la Lucha contra el Terrorismo,

tiene por objeto coordinar las actividades del sistema de las Naciones Unidas en apoyo

de la Estrategia Global de las Naciones Unidas contra el Terrorismo, aprobada por la

Asamblea General en su resolución 60/288, en la que los Estados Miembros decidieron

“coordinar los esfuerzos en los planos internacional y regional para combatir el terrorismo en todas sus formas y manifestaciones en Internet” y “utilizar Internet como

instrumento para luchar contra la propagación del terrorismo, y al mismo tiempo

reconocer que los Estados podrían necesitar asistencia a este respecto”. El Grupo de

Trabajo ha señalado tres temas clave para su examen: cuestiones jurídicas, cuestiones

técnicas y formas en que la comunidad internacional podría utilizar Internet más eficazmente para combatir el terrorismo poniendo en descubierto la falacia del mensaje

terrorista de que la violencia es una forma legítima de lograr el cambio político.

El presente estudio, preparado por la Oficina de las Naciones Unidas contra la Droga

y el Delito y llevado a cabo en el marco del Grupo de Trabajo, se realizó en gran

medida gracias a la contribución y al apoyo de los Estados Miembros. En él se lleva

el examen de los problemas jurídicos a una nueva etapa y se hace una valiosa contribución a los conocimientos y la experiencia que el Grupo de Trabajo ha acumulado

y compartido con los Estados Miembros en este ámbito. En particular, proporciona

ejemplos importantes de la legislación de los Estados Miembros relativa al uso de

Internet por terroristas y demuestra, por medio de ejemplos de casos judiciales reales,

las dificultades que enfrentan los Estados Miembros para penalizar y enjuiciar tales

actos.
