aleksandrvk [35]

Answer: seen below

Explanation:

1) The olfactory receptor can recognize and respond to different ordor, For humans, most odorant molecules are made up of combinations of 5 kinds of atoms: these are, carbon, hydrogen, oxygen, nitrogen, and sulfur.

2) yes, scent is subjective. This is because there is likely variation in people's sensitivity to odor or personal appreciation of different odors. Not everyone smells the same thing.

3) The two proposed theories for the mechanics of scent recognition are; vibration theory and shape theory which is also called the lock and key model. The main problem with one of Turin theories is that we can't currently predict odor character from vibration any better than we can from shape. That is we are still terrible at predicting ordor character from molecular structure.

4) Science has contributed to the creation of scented products and perfumes by having chemical Mixtures Tested in labs and addition of substances for smell.

5) Scents or fragrances are used in cosmetology as perfumes, lotions, shampoos, face washes, body cream, conditioners, etc. Cosmetologist need to be aware of scents and fragrances because if a perfume had a scent that did not smell right then no one would want to purchase their product.

2. Based on your answer to question 1, what do you think could be done to reduce levels of
levacccp [35]

Answer: Carbon dioxide (CO2) is a colorless gas that is naturally present in the air as a result of the natural carbon cycle of our planet. While emissions come from many natural sources, it is the CO2 produced by manmade processes such as fossil fuel combustion and power plant emissions that are problematic. This, in combination with the destruction of natural carbon dioxide sinks through deforestation, is creating an unhealthy environment on our planet and contributing significantly to climate change. here are other things still that can be done to help improve our carbon dioxide situation, even if they aren't tasks the average person can control. For example, as a society, we must continue to push for improved technology in our power plants, so our energy consumption does not produce as much waste.  Improving technology will also help more directly with how much electricity we use. Appliances and electronics are more efficient now than they have ever been in the past, but we should always strive for better regardless. Doing your individual part may not seem like much in the grand scheme of things, but if everyone does their best, it will eventually add up to a significant improvement in the fight against climate change.
