What are the primary atoms that make up the scents that we smell? 2. is scent subjective? why or why not? 3. what are the two di
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.

Aleksandr [31]

Answer:

Explanation:

Given:

Traits

T (tall, dominant) and t (short)

R (round, dominant) and r (wrinkle)

Crossing parents

<u>hetero-zygous. tall wrinkled (</u><u>Ttrr</u><u>)</u>

phenotype tall is given hetero-zygous., so Tt

phenotype wrinkled is recessive, so must be homo-zygous rr

<u>Foiled genotypes</u> (Tr, tr, each with 50%)

<u>short hetero-zygous. round (</u><u>ttRr</u><u>)</u>

phenotype short is recessive, so homo-zygous rr

phenotype round is given heteroz. so Rr

<u>Foiled genotypes</u> (tR, tr, each with 50%)
