Electrons (negatively charged subatomic particles)
Okay so i hope this help but i think its this:
1. chlorophyll, a green pigment found in the leaves of plants (see the layer of chlorophyll in the cross-section chlorophyll, a green pigment found in the leaves of plants (see the layer of chlorophyll in the cross-section
2. light (either natural sunlight or artificial light, like from a light bulb)
3. carbon dioxide (CO2)(a gas found in the air; one of the gases people and animals breathe out when they exhale)
4. water (which the plant collects through its roots)
5. nutrients and minerals (which the plant collects from the soil through its roots)
Did researching for you so I hope this helped? :)
The dependant variable would be the salmon, because they depend on the water and pollution levels to give a result.
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.
