The right answer is D. renal regulation.
Among the many factors that modulate tension (vessels, heart strength, blood volume ...), the kidney plays a vital role because it makes an enzyme called renin that helps increase blood pressure and it regulates the outflow of sodium and water, which contribute to the elevation or diminution of blood pressure in the arteries.
Answer:
The post-transcriptional modifications in the mRNA produced as a result of the transcription in eukaryotes provide many advantages to the mRNA.
The two post-transcriptional modifications are the addition of 7-methylguanosine cap at 5' end of mRNA called capping whereas the addition of the poly(Adenyl) tail at 3' end called tailing.
The advantages of capping are:
1. Protection of nascent mRNA from the degradation.
2. Recognition by transcription factors helps in translation.
The advantages of tailing are:
1. Protection of the mRNA from enzymatic degradation in the cytosol.
2. Transcription termination
3. Export of the mRNA from the nucleus
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.
