In which of the domains would it be easiest to determine the phylogenetic relationships among organisms?
ioda

The study of relationships and the evolutionary history of various groupings of species is known as phylogeny. The goal of phylogeny is to reconstruct the evolutionary course of all species on Earth. A phylogenetic tree also learned as a cladogram, is a schematic diagram used to show the alleged evolutionary relationships between taxa. Diagrams of phylogenetic trees are based on cladistics, or phylogenetic systematics, hypotheses.

Organization of life, according to taxonomy, divides creatures into three domains:

  • Bacteria
  • Eukarya
  • Archaea

The Eukarya domain are the most easy because they are large enough for their morphological features to be easily seen.

s2008m [1.1K]

Answer:1Zn+2HCl------1ZnCl2+1H2

Explanation:

A single replacement reaction is one in which a more reactive element displaces a less reactive element from its salt solution.Thus zinc can easily lose electrons as compared to hydrogen and result in the formation of zinc chloride and hydrogen.

According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.
