The 5 branches are organic, inorganic, biochemistry, analytical, and physical. There are different branches because they each apply to different parts of chemistry. For example organic chemistry is the study of carbon compounds and inorganic chemistry is the study of non carbon compounds. You can't just have one type of chemistry because these are very different.
Answer:
Over the last century the burning of fossil fuels like coal and oil has increased the concentration of atmospheric carbon dioxide (CO2). This happens because the coal or oil burning process combines carbon with oxygen in the air to make CO2. as u know decreasing means going down and increasing means going up. the reason why things decrease means something went wrong or something to happen to make it go down we all try to make things increase which means we try to make things go up instead of down. a lot of reasons is y things decrease is bc during the period of time something might go wrong or happen in a bad way that makes a lot of things decrease. for example like temperature when the temperature decreases it means it goes down and it might get cold but if the temperature increases it goes up so it might be ht or warm or maybe even cool. if something ever decreases it means during the period of time something bad happened and made it go down instead of up if something ever goes wrong that means something decreased. sometimes decreasing could be a good thing but most of the time it it bad but there are sometimes when decreasing is good but not all the time.
Your pattern of breathing increases, making it faster than usual, when you're exercising because you're pushing your body to work harder and speeding up your heart rate making you tired.
When you're resting your breathing pattern should be steady and normal since you aren't doing anything that requires lots of body work or something that would make you out of breath.
