Answer: PTC gene has two main alleles; one that codes for tasting and the other non-tasting. The allele for tasting determines a trait of tongue papillae that can bind the PTC molecules. Non-tasting allele forms papillae that are unable to bind PTC effectively. Therefore, the combination of these alleles in the genotype of a person determines their phenotype – PTC sensitivity.

Answer:

Individuals are often characterized as “tasters” or “non-tasters” of PTC, but there is some variability amongst tasters in how much bitterness they can detect. ... The ability to taste PTC is due changes in the TAS2R38 gene that affects the function of bitter taste receptors on the tongue therefore, the combination of these alleles in the genotype of a person determines their phenotype – PTC sensitivity.

Which of the following equations represents the right chemical process that occurs in photosynthesis? Question 8 options: A) Six
AlexFokin [52]

Six molecules of carbon dioxide plus six molecules of water plus light energy converts to six molecules of oxygen plus sugar, Thus, the correct option is A.

<h3>What is photosynthesis?</h3>

Photosynthesis is the process through which plants use sunlight to create their own nourishment. Through a sequence of reactions, light energy from the sun is turned into chemical energy, which is then stored in the form of food.

In the presence of sunlight, 6 molecules of carbon dioxide (CO2) and 6 molecules of water (H2O) react to form 1 molecule of glucose sugar. During photosynthesis, 6 molecules of oxygen are formed in addition to glucose.

The following is a balanced chemical reaction for photosynthesis:

   

                                     Sunlight

6CO2    +              6H2O  —---------> C6H12O6 +     6O2.

(carbon                (water)                  (glucose)       (oxygen)  

dioxide)
