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:
In <u>asexual </u>reproduction, genetically identical offspring are produced, while in <u>sexual </u>reproduction, offspring are genetically different from each other.
Sexual reproduction is a sort of reproduction that involves a complex existence cycle wherein a gamete (inclusive of a sperm or egg mobile) with an unmarried set of chromosomes (haploid) combines with another to provide a zygote that develops into an organism composed of cells with two sets of chromosomes (diploid).
Sexual reproduction is the maximum common existence cycle in multicellular eukaryotes, which includes animals, fungi, and plants.
Asexual reproduction is a sort of reproduction that doesn't involve the fusion of gametes or change in the number of chromosomes. The offspring that get up by asexual reproduction from both unicellular and multicellular organisms inherit the whole set of genes in their single parent. Asexual reproduction is the number one shape of reproduction for single-celled organisms including archaea and bacteria.

only sucrose is a non reducing sugar
The answer is A. Hardness
The smaller veins in the leaf connect to the <u>margin </u>of the leaf.
<u>Explanation:</u>
The structural and important part of the plant is the leaf. The leaf is the main source of photosynthesis. The leaf has small vein like structures to carry the prepared food and energy sources to be distributed throughout the plant.
The smaller veins in a netted pattern run across the leaves to meet the margin of the leaf. The veins run laterally from the midrib to the margins hence providing a proper network and hence passing of the nutrients made feasible in an accommodative way.
