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.

Use the double-stranded DNA molecule below to answer the following questions. The first pair of nucleotides (bolded) contains th
krok68 [10]

Answer:

The correct answer is 2. 5'-AUGUCAGGUACGCCACAU-3'

Explanation:

The template strand for transcription is 3'-TACAGTCCATGCGGTGTA-5 and RNA polymerase will add complementary mRNA sequence against this strand in the opposite direction i.e., 5' to 3' direction.

In RNA, A(adenine) makes complementary base pairing with U(uracil), not with T(thymine) and the rest of the base-pairing is same as in DNA. Therefore the correct mRNA produced from the transcription of this DNA molecule by the help of RNA polymerase is 5'-AUGUCAGGUACGCCACAU-3'.

Then this mRNA sequence will be used by ribosomes to synthesize proteins during the translation process.

A substance that moves from by passive transport tends to move
makvit [3.9K]
You see, passive transport needs no energy. So that being said, it moves from areas with high concentration to areas with low concentration.

Hope that helps!
