Taste - correct answer -orally, humans perceive a variety of chemical compounds in food that we describe as bitter, sweet, sour, salty, and umami -in realtiy, our perception of taste is much more complicated than this, and variation in taste sensitivity appears to be at least partially genetic in origin. -taste sensitivity to some bitter compounds has received considerable attnetion in anthropology. Phenylthiocarbamide (PTC) - correct answer ...

PTC Lab Test- Biotech Questions And Answers 2024/2025 What does PTC stand for? How was it discoverd? - ANS-PTC- phenylthiocarbamide PTC was discovered by Arthur Fox in 1931 when he poured PTC powder in bottle and some accidentally blew in the air; many near him claimed the dust tasted bitter but he could not taste anything ; this accident discovered that some thought it tasted really bitter, slightly bitter, and no taste at all. How many genes are involved in tasting PTC? - ANS-1 allele ...

objective - correct answer characterize each student's ability to detect bitterness using a PTC test strip; assess if response to unsweetened grapefruit juice correlates with PTC test strip results; determine the density of taste bud-containing fungiform papillae (visual assay of the anterior aspect of student's tongue; correlate with PTC test strip and grapefruit juice responses); isolate DNA (saline mouth wash extraction), PCR amplify and (HaeIII...

DNA is used as a template for making correct answer: proteins and RNA. A student was testing whether PTC tasting ability correlated with amount of coffee consumed. She tested determined the lowest concentration of PTC that an individual could taste and rated it on a scale from 1-14. Then, she surveyed each individual about the number of cups of coffee that they consume a week. Her data can be seen below. correct answer: here does not appear to be a relationship between PTC tasting and coffe...
