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.
Answer:
a) 28 cases
b) 3 cases
Explanation:
a) From the table of genetic codes, there are 28 codons that specify more than one amino acid assuming only the first two nucleotides are considered. In these cases, one cannot outrightly specify the amino acid the genetic codes are coding for without knowing the last nucleotide of the codes. <em>For example, UU can be for Phenylalanine or Leucine, CA can be for Histidine or Glutamine, etc. </em>
b) From the table of genetic codes, the first two nucleotides of Arginine can be either of CG or AG, that of Serine can be either of UC or AG while that Leucine can be either of CU or UU. Only in these <u>3 cases</u> would one fail to know which are the first two nucleotides assuming the name of the amino acids are given.
