Answer:
Aspartame is found in Nutra sweet which is a modified dipeptide rather than a carbohydrate and they are many times sweeter than monosaccharides galactose because they binds very tightly with the heterodimer GPCR receptors present on the tongue which is made up of proteins called taste receptor type 1 member 2 and taste receptor type 1 member 3.
This tight binding to aspartame generates a neuronal output that is sent to the brain and the brain interprets it as a super sweet compound. It's decrease off rate also contribute to its more sweetening effect.
Therefore the type of binding to taste receptors explains why aspartame is 500 times sweeter in human taste test.
Answer:
No
Explanation:
A period is when your body produces a layer of tissue and blood to protect the baby. But the period is when your body is like "oops, false alarm" and disposes of the tissue and blood. During pregnancy, the baby is kept safe by the tissue and blood, that is why women don't have periods during pregnancy.
Answer:
When it comes to crickets, fitness means one's reproduction in producing as many offspring as possible, so the chances of their offspring living are higher. In addition, the passing on their genes is the most important for their offspring's evolution.
Answer:
A malaria outbreak causing allele frequencies to change is an example of <u><em>natural selection.</em></u>
Explanation:
Natural selection is a type of selection in which those organisms are favoured to live and reproduce which are better adapted to live in an environment. Due to natural selection, the allele frequencies of a population will tend to change with the passage of time.
When the outbreak of malaria occurs, those organisms which do not catch malaria are able to survive and pass on their characteristics to their offsprings. the other organisms die and do not reproduce. This will cause changes in the allele frequencies.
Answer:
