When a compound donates (loses) electrons (hydrogen ion), that compound becomes such a compound is often referred to as an electron donor.

Oxidized

Explanation:

Compounds that lose or donate electrons are also called electron donors. They act as reducing agents in chemical reactions where they reduce the oxidation states of compounds they react with and they become oxidized themselves.

For example; in the reaction between Hydrogen gas and oxygen to form water

2H+ + O2- > H20

Two hydrogen atoms donate their electrons to an oxygen atom, reducing the oxidation state of oxygen to 2- and oxidized itself to +1

is this for the e2020 class

dna fingerprinting is defined as a process that determines the dna characteristics of an individual. these dna characteristics are unique among individuals as their fingerprints, so it is known as dna fingerprinting.

steps of dna fingerprinting includes extraction of dna from sample, amplification of dna, restriction digestion of amplified dna, and then analysis of dna by gel electrophoresis, respectively.

thus, the next step performed by the scientist is 'to cut the amplified dna (obtained by polymerase chain reaction) by restriction enzymes that cleave the dna into fragments and their analysis.'
