Answer:

They developed a test for poisons in the human tissues

Explanation:

Around the 19th century, Mathieu Orfila and Robert Christison developed important tests that identified poisons in human tissues.

By so doing, they laid the foundation for what is now called forensic toxicology. This science attempts to identify poisons in human tissues especially by way of autopsies and forensic investigation.

Today forensic toxicology has expanded to include alcohol testing techniques as well as testing athletes for intake of performance enhancing substances.

Answer:

About 4,000 K and 10⁻¹⁷ atm

Explanation:

The Big Bang theory states that the Big Bang which is the origin of the universe was about 13.75 billion years ago, and the temperature a few seconds later was 10³²K

The first element began forming at about 3 minutes after the Big Bang with a temperature of 10⁹ K, the nuclei of simple elements

The nuclei of hydrogen and helium began combine with electrons at a temperature of 3,000 K to 4,000 K to form the first neutral atoms. The pressure of the universe at that stage was 10⁻¹⁷ atmospheres
