A is the answer I think hoped I helped
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.

Answer:
The outcome of cell‐lineage competition is likely to depend, among other factors, on the initial number of cells involved. Mosaicism generally starts as one or a small group of mutant cells while chimerism generally involves a more massive input of genetically different cells
Explanation:
Answer:
The correct answer would be d) summarized data.
The summarized data gives the quick and easy description of all the observations obtained in the experiment.
The data can be summarized using different categories such as the total of the observations, frequency of the observations, mean value, variation et cetera.
It helps in deducing any conclusion from the observations such as the pattern of increase or decrease in the biological activity.
