What information would be most relevant to determining the time of death?
Nuetrik [128]

Lividity can be defined as the typical bluish-purple discoloration of the skin after death. Rigor mortis can be defined as the postmortem state in which the muscles become stiff.

  • After death, the stomach contains identifiable ingested foods within two hours.

  • Rigor mortis is characterized by the stiffening of the body after death, which is caused by the absence of ATP in muscle tissues.

  • Postmortem lividity or livor mortis is caused by the accumulation of blood in blood vessels (the lack of arterial pressure) as a result of gravity.

  • The most relevant information to determine the time of death is the presence of lividity, rigor mortis, and/or stomach contents (Option c).

Darker skin is more prevalent in high-UV areas. Dr. Nina Jablonski proposed a hypothesis to explain the selective pressure for d
skad [1K]

The answer is; the melanin in darkly pigmented skin protects DNA from UV radiation, and UV radiation can cause skin cancer

In Africa, due to its equatorial latitude location, receives direct sunlight at more or less 90 degrees most of the year. These highly concentrated rays increase the UV radiation exposure  that can cause damage to cell DNA. Selection pressure, therefore, favored individuals with high melanin concentrations that protect against UV. Therefore population evolved towards high melanin densities in the skin.
