The answer is CAG, look where it is on the chart
The answer is protect the body from infection by pathogens
The physical barrier is made of epithelial cells, mostly will be keratinized to increase their sturdiness further. They will impede the pathogen physically by barricading the cells, makes the pathogen could not invade deeper part of the body. Histamine and antibodies should be the role of immune cells, not epithelial.
They would test two subject/mice which is S-Strain and R-Strain to see the differences and scientific behavior. In the end one died which is S-Strain and the other lived which he later affirm the transforming principle by testing with the chemical itself. In turn out comes the Answer
Answer:
The correct answer is C. Burning fuel releases carbon monoxide and other chemicals into air.
Explanation:
The burning of flue realeases carbon monooxide which is highly reactive.Carbon monoxide binds with hemoglobin resulting in the formation of carboxy hemoglobin.
Carbon monoxide interacts binds high affinity to hemoglobin than oxygen.The binding of carbon monoxide to hemoglobin displaces the oxygen from hemoglobin thus reducing the affinity of the later for oxygen.
When carbon monoxide binds to hemoblobin, then less hemoglobin is available to bind and transport oxygen to the peripheral tissues of the body..An exposure to carbon monoxide for long period of time can cause death.
Answer: Antibiotics are ineffective against viruses.
Explanation:
Viruses such as enterovirus and coronavirus have been implicated in the cause of respiratory tract infections. And because unlike bacteria, these viruses do not have a cell wall, independent metabolic machinery: antibiotics are ineffective against viruses.
