VikaD [51]

No there is no selective pressure that confers an advantage to those who do taste it.

<h3>What is PTC?</h3>

Despite the fact that PTC isn't found in nature, tasting other bitter substances—many of which are toxins—that do occur naturally has a high correlation with taste sensitivity.

In order to defend themselves from being eaten, plants develop a range of harmful substances. Early humans developed the capacity to distinguish bitter tastes as a safeguard against ingesting dangerous plants. There are roughly 30 genes in humans that produce bitter taste receptors. People may taste a large variety of bitter substances because each receptor can interact with a number of different molecules.

The nervous system has three general functions: a sensory function, an interpretative function and a motor function. 1. Sensory nerves gather information from inside the body and the outside environment. The nerves then carry the information to the central nervous system (CNS). 2. Sensory information brought to the CNS is processed and interpreted. 3. Motor nerve cells convey information from the CNS to the muscles and glands of the body. The nervous system is responsible for coordinating all of the body's activities.</span>

If you eat a lot of food, will you gain weight? Explain why or why not.
natka813 [3]
The accurate answer to this is: it depends.

The type of food a person eats can affect him or her differently than another type of food. An additional factor is how active the person is.

For example, if a person does not exercise and eats McDonalds constantly, he/she is more susceptible to weight gain than a person who exercises often and eats healthy foods.In addition, the amount of calories a person eats and burns has an affect on the person's weight gain.

I hope this answers your question!
