<u>ANSWER:</u>

Cosmic background radiation is leftover thermal energy from the Big Bang best describes the origin and expansion of the universe.

<u>EXPLANATION:</u>

  • The "Big Bang Theory" is used to describe how the universe has begun.
  • The theory basically states that the "universe" began as a "single point" and then "expanded and stretched" and is expanding even today.
  • When the universe began, it was "hot tiny particles" mixed with heat and light and as it "expanded" and took up "more space", it cooled down and formed atoms.
  • The "best evidence of the big bang" is the radiation of cosmic background that was leftover when the first big bang explosion took place and began the universe.

10. A body is found at 2:00 pm on New Year's Eve. The temperature of the liver registers 75.5° F. What is the
EastWind [94]

Given what we know about the correlation between the liver temperature of a corpse and the estimated TOD, we can conclude that the estimated time of death is approximately 10:30 pm of the night before.

<h3>How do we estimate the TOD?</h3>
  • This can be achieved using a mathematical formula.
  • The formula in question involves taking the normal body temperature of a living human and subtracting the liver temperature of the body.
  • The remaining is the difference in temperature.
  • Given that a body will lose roughly 1.5 degrees worth of heat per hour, we divide the remaining number by this to get the amount of hours since the death.
  • This leads us to the conclusion that this individual perished roughly 15.5 hours earlier.

Therefore, given the way in which we use the correlation between liver temperature and time to analyze and approximate a time of death, we can confirm that this individual will have perished at roughly 10:30 pm of the night before.
