was it the revolution
Outdoor air pollution became a significant problem around the time of the Industrial Revolution due to the increase in industries and coal usage. Heavy industrial cities like London witnessed severe air pollution. However, smaller-scale air pollution has existed since prehistoric times.
Yes, you are correct in assuming that outdoor air pollution became a significant issue around the time of the Industrial Revolution. Beginning in the late 1700s, with the advent of new technology and the increased use of coal as a fuel source, industries began to emit larger amounts of smoke and soot, significantly degrading air quality. Cities fluid in manufacturing, like London, experienced severe air pollution issues, sometimes leading to events such as the 'Great Smog' of 1952. However, it is important to note that forms of air pollution have existed for centuries before the Industrial Revolution, such as dust and smoke from burning wood during the prehistoric era.

Ok so in this experiment what we want to find is the catalyst for the reaction. Our original reaction is the following. A + B --> C, therefore to find which of the unknown substances (X, Y, and Z) is the catalyst reaction we simply have to do the following:
A + B + X --> C
A + B + Y --> C
A + B + Z --> C
The reaction that produces C much faster than our original reaction A + B --> C will be our catalyst. The reason being that one of the substances will increase the rate of the chemical reaction.
I hope it helps, Regards.
Answer:
Prepare three test tubes containing reactant A.
Prepare three test tubes containing reactant B.
Add one test tube of reactant B and one unknown to one test tube of reactant A. Repeat for the other two unknowns.
Time the reaction until bubbling stops.
The unknown that causes the reaction to occur the quickest is the catalyst.
I took the test
Answer:
on the red blood cell membrane
The antibodies related to the ABO blood group are located in the blood plasma. They react with the corresponding antigens present on the surface of red blood cells. The type of antigens and antibodies vary depending on the ABO blood type of an individual.
The antibodies related to the ABO blood group are located in the plasma of our blood. These antibodies respond to the ABO blood group antigens that are present on the surface of red blood cells (erythrocytes). If an individual has type A blood, they will have A antigens on the surface of their red blood cells and anti-B antibodies in the plasma. Conversely, an individual with type B blood will have B antigens on their red blood cells and anti-A antibodies in their plasma.
Those with type AB blood carry both A and B antigens on their red blood cells but do not produce any antibodies against A or B in their plasma. Lastly, individuals with type O blood do not have any antigens on their red blood cells, but they produce both anti-A and anti-B antibodies in their plasma. This system is crucial to know for blood transfusion procedures as mixing incompatible blood types can result in a dangerous immune response.
