Breathing is the process of moving air out and in the lungs and Respiration is the movement of oxygen from the outside environment to the cells within tissues, and the removal of carbon dioxide in the opposite direction.
This would be an example of negative feedback because the body isn’t trying to surpass a set point. It’s trying to maintain the amount of food in the stomach at that point.
The answer is A. It can be scientifically found while the other answer choices are all peoples personal opinions, not scientific facts like measurement.
Coal contains sulfur and other elements, like dangerous metals (mercury, leads, and arsenic) that get into the air when coal is burned. Burning coal releases particulates and cause an increase in air pollution, it also emits the amount of CO2 (carbon dioxide) in the atmosphere
The mechanism of action of Bordetella pertussis is to stop the cilia of epithelial cells from beating.
<em>Bordetella pertussis</em> is a pathogenic, gram-negative bacteria. It is the causative agent of highly communicable respiratory disease known as pertussis or whooping cough.
The mechanism of action of Bordetella pertussis:
- This bacterium colonizes the ciliated epithelial cells of the respiratory airways of the host.
- A surface protein on the bacteria called filamentous haemagglutinin adhesin binds to sulfatides on the cilia of epithelial cells. When the bacterium is anchored, it releases tracheal cytotoxin, which prevents the cilia from beating.
- As a result, the cilia in an organism's lungs are unable to sweep out foreign material, and the body reacts by causing the host to cough. When people cough, bacteria are released into the air, where they might spread to other hosts.
- Another toxin called the pertussis toxin, often known as PTx, prevents adenylate cyclase from using ATP to convert to cyclic AMP. This results in over-conversion of ATP to cyclic AMP, which may interfere with cellular signaling systems. As a result, phagocytes are unable to respond to an infection effectively.
