Answer:
1.The pleural cavity aids optimal functioning of the lugs during breathing. It transmits movements of the chest wall to the lungs, particularly during heavy breathing. The closely approved chest wall transmits pressures to the visceral pleural surface and hence to the lung (10-19.
2.The diaphragm, located below the lungs, is the major muscle of respiration. It is a large, dome-shaped muscle that contracts rhythmically and continually, and most of the time, involuntarily. Upon inhalation, the diaphragm contracts and flattens and the chest cavity enlarge.
Explanation:
The inner planets are made of rocks while the outer planets are composed of gas.
The inner planets are closer to Sun and are small in size while the outer planets are far away from sun and are larger in size
It is gotten from the atmosphere by respiration, burning of fossil fuel, decay, excretion and decomposition of organic matter, fossilization etc
Answer:
d. disrupt the function of protein kinases involved in cell cycle regulation.
Explanation:
Protein kinases which are useful in cell cycles have major roles in the formation of tumors. So many of these protein kinases go through mutations. Cell cycles would be unable to be stoped and tumor would keep increasing.
A lot of receptors are G protein coupled. So it is going to be really helpful to alter and make G protein receptors to be inactive. Most if these kinases go through means of phosphorylation and dephosphorylation. Targeting these would cause disruption in signal transduction in cells with cancer
