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.

The urban environment usually refers to the city, like Chicago. Urban is the opposite of rural. The rural area is known as the countryside. Urban environments often include; tall skyscrapers, loud streets, and the smells of different kinds of foods.
You can't change a law, because it's just an observation or statement of fact like gravity makes things move toward each other.
It's not an observation because you can't physically see traits being inherited.
It may be a changing theory or a changing hypothesis.
Answer:
The correct answer is A. The larynx moves up against epiglottis when food is swallowed to prevent passage of food into it.
Explanation:
The epiglottis is a moist, cartilaginous structure that is part of the cartilaginous skeleton of the larynx. It also marks the boundary between the oropharynx and the laryngopharynx. The epiglottis obstructs the passage of the bolus at the time of swallowing preventing it from going to the respiratory system.
Larynx closure occurs when the vestibular and vocal folds approach the midline during swallowing. Occasionally, when you eat very fast, solid foods or liquids can enter the larynx.
