Phenoloxidase system is a major defense system in many invertebrates which ultimately leads to melanization of pathogens and damaged tissues. The process of melanization depends on activation of the enzyme [[phenol xidase]] (PO) which is controlled by the prophenoloxidase (proPO) activation system. During activation of proPO cascade, many other immune reaction are produced, such as cytotoxic, opsonic and encapsulation activities. The phenoxidase cascade plays an important role in invertebrates (especially insects) in three physiologically important processes: immune reactions, sclerotization of the cuticle and wound healing.

The inquiry reported that Trump withheld military aid and an invitation to the White House to Ukrainian President Volodymyr Zelensky in order to influence Ukraine to announce an investigation of Trump's political opponent, Joe Biden, and to promote a debunked theory that Ukrainians framed Russia for breaking into a DNC email server during the 2016 U.S. presidential campaign. The inquiry stage of Trump's impeachment lasted from September to November 2019, in the wake of an August 2019 whistleblower complaint alleging Trump's abuse of power.

In November, the House Intelligence Committee held a number of public hearings in which witnesses testified publicly; on December 3, the committee voted 13–9 along party lines to adopt a final report.A set of impeachment hearings before the House Judiciary Committee began on December 4; on December 13, it voted 23–17 along party lines to recommend two articles of impeachment, for abuse of power and obstruction of Congress. The committee released a lengthy report on the impeachment articles on December 16. Two days later, the full House approved both articles in a near-party-line vote, making Trump the third U.S. president in history to be impeached. According to the Senate's impeachment rules adopted in 1986, the articles' submission to the Senate initiates the trial – which is expected to begin as early as the second week of January 2020.
