The answer is that all of them are unreactive gases because they're all noble gases which means they don't react with anything.
Hope this helped you :))
Las actividades económicas tienen que ver con la obtención de alimentación, medicinas, madera y leña. Además de la elaboración de carbón y materiales para curtir pieles. Además de eso ha habido visitas turisticas, la pesca deportiva y la observación de aves. La verdad ha sido mas el perjuicio que el beneficio. El beneficio es completamente económico pero entre los perjuicios esta la contaminación del agua por la construcción de presas y el cambio de suelos por la contruccion de varios proyectos
Answer: The relationship between blood pressure and heart rate responses to coughing was investigated in 10 healthy subjects in three body positions and compared with the circulatory responses to commonly used autonomic function tests: forced breathing, standing up and the Valsalva manoeuvre. 2. We observed a concomitant intra-cough increase in supine heart rate and blood pressure and a sustained post-cough elevation of heart rate in the absence of arterial hypotension. These findings indicate that the sustained increase in heart rate in response to coughing is not caused by arterial hypotension and that these heart rate changes are not under arterial baroreflex control. 3. The maximal change in heart rate in response to coughing (28 +/- 8 beats/min) was comparable with the response to forced breathing (29 +/- 9 beats/min, P greater than 0.4), with a reasonable correlation (r = 0.67, P less than 0.05), and smaller than the change in response to standing up (41 +/- 9 beats/min, P less than 0.01) and to the Valsalva manoeuvre (39 +/- 13 beats/min, P less than 0.01). 4. Quantifying the initial heart rate response to coughing offers no advantage in measuring cardiac acceleratory capacity; standing up and the Valsalva manoeuvre are superior to coughing in evaluating arterial baroreflex cardiovascular function.

Explanation:
there is a high rate of rainfall in rainforest, therefore amount of rain fall being abiotic factor can affect rain forest
