The defense system of the human body is made up of entire organs and vessel systems like the lymph vessels, but also of individual cells and proteins. The inner and outer surfaces of the body are the first barriers against pathogens (germs). These surfaces include the skin and all mucous membranes, which form a kind of mechanical protective wall.
Several things support this protective wall:
<span><span>- The body’s own antibacterial substances can disable different pathogens from the environment at an early stage. A certain enzyme found in saliva, the airways and tear fluid destroys the cell walls of bacteria.
</span><span>
- Many pathogens that are breathed in get stuck to mucus in the bronchi and are then moved out of the airways by hair-like structures called cilia.
</span><span>
- Most pathogens that enter the body together with food are usually stopped by stomach acid.
</span><span>
- Normal flora, harmless bacteria that reside on the skin and many mucous membranes in the body, also help to protect the body.</span></span>
The cough and sneeze reflex can also help to remove pathogens.
Hope this helps (:
<u>The equation that shows the decomposition of silver carbonate are;</u>
2Ag2CO3 ---------> 4Ag + 2CO2 + O2
<u>From the periodic table:</u>
Mass of silver = 107.8682 grams
Mass of carbon = 12 grams
Mass of oxygen = 16 grams
Molar mass of Ag2CO3 = 2(107.8682) + 12 + 3(16) = 275.7364 grams
<u>From the balanced equation above:</u>
2(275.7362) = 551.4728 grams<em> of</em> Ag2CO3 <em>produces</em> 4(107.8682) = 431.4728 <em>grams of Ag</em>
<u>Thus, in order to know the mass of Ag produced from 2.76 grams of Ag2CO3, we'll use the cross multiplication method; </u>
Mass of Ag produced = (2.76 × 431.4728) / (551.4728) = <em>2.16 grams</em>
Based on the calculations demonstrated above, the law of conservation of mass is applied.
Answer:
Explanation:
Leison is what is been seen in the brain as white Spot it is as a result of activities carried out in the brain. MR monitors how blood flows into a part of the brain will then transfer the lesion into the brain.
Myaline sheets surround the nerves cells forming a layer round the axons.
Break down of Myaline sheathe leads random shot of neurons this then result in white leison. The leison disappers after the myelin sheat have been healed or repaired by the actions of the neuron present.
Neurons then carries signals or impulse that the myelin sheat have been fixed.
"The hypothesis is always supported in the end" is the one statement among the following that <span>is true about the scientific process. The correct option among all the options that are given in the question is the first option. I hope that this is the answer that has actually come to your help.</span>
