Answer:
Reversible reaction
Explanation:
If the elements of the product combine together in a chemical reaction, this reaction is called reversible reaction because the reaction moves in backward or reverse direction. For example, if acid i. e. HCl combine with base i. e. NaOH which are the reactants, it produces two products salt (NaCl) and water (H2O). If salt (NaCl) and water (H2O) combine again with each other, it produces acid i. e. HCl and base i. e. NaOH, such type of reaction is called reversible reaction.
This man is presenting with signs/symptoms of an inferior wall M.I. (myocardial infarction), a heart attack. He needs to be started on IV fluids with morphine, oxygen, nitroglycerin, and aspirin. However, it is imperative that before administering nitro/nitrates, he denies having taken any sexual meds for erectile dysfunction (e.g. Viagra) within the past 24 hours. That combined with nitrates can lead to a life-threatening irreversible crash of central blood pressure around the heart.
Answer:
Speciation is defined as an evolutionary process in which one population evolves into a distinct species.
Speciation in reverse, or despeciation is defined as the extinction of an old species due to combining with evolved species to produce hybrid species but it conserves biological lineage.
In the given research, the term used despeciation or speciation in reverse is appropriate as hybrid species resulted from interbreeding of Galapagos two finch species conserved the biological lineage but also loss one of the species Darwin discovered.
