Explanation:
The time taken by light to reach pluto will be 5.6 hours.
<h3><u>Explanation</u>:</h3>
The light is a electromagnetic wave that has the highest velocity and same velocity as all other electromagnetic radiations existing in this universe. The light takes about 8.2 seconds to reach from sun to earth. So lets check howmuch time does light take to reach pluto from sun.
The speed of light was calculated to be
m/s. This is the speed of each and every electromagnetic waves.
The distance of pluto from sun is huge. On an average it's
km or
m.
So time taken by light to reach from sun to pluto will be
seconds. Or actually 5.6 hours.
Answer is Middle Paleozoic era.

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.
