During exercise, a number of changes occur to maximise the body's oxygen intake. Firstly our heart rate/ pulse increases. This is due to the heart beating much faster and more forcefully to pump blood faster around the body.
Our breathing rate increases to intake more oxygen and exhale more CO2.
The smooth muscle in our trachea and bronchi relaxes to increase the lumen size thus making breathing easier. Adrenaline may also be released leading further amplifying these changes as well as reducing blood flow to the gut and thus peristalsis occurs at a much slower rate.
Also when we exercise we respire more, producing heat, which must be expelled. This may be done through sweating. Another physiological change that occurs is vasodilation of arterioles closer to the skin to allow more blood to flow closer to the skin, allowing more heat to radiate out.
Answer:
Proton motive force, compounds such as ATP.
Explanation:
Large amount of proton motive force(PMF),the usable enegy for the cell ,are produced during electron transport chain when high energy compound such as ATP pump hydrogen ions against the concentration gradient.
When the protons are transported against their concentration gradient at that time proton motive force is generated.
PMF generates energy for the synthesis of ATP by the phosphorylation of ADP with inorganic phosphate.
Answer:
B). Publication page.
Explanation:
A literary text consists of a number of sources that provide various information to the readers regarding the work like title page, index, bibliography, title page, etc. with each having a distinct role(information) to play(display).
As per the question, '<u>publication page</u>' is characterized as the information source that presents the significant details regarding the publication of the book like the information about the copyright of the book and legal disclaimers along with the edition number. This page is primarily included to establish/claim the legal right of the author over the book and inform the readers about the same. Thus, <u>option B</u> is the correct answer.
The answer is osteoclasts
