The hydrogen ion concentration of a solution is indicated by its <u>pH </u>value.

Explanation:

  • A measure of acidity or alkalinity of water soluble substances (pH stands for 'potential of Hydrogen'). A pH value is a number from 1 to 14, with 7 as the middle point.
  • Under normal circumstances this means that the concentration of hydrogen ions in acidic solution can be taken to be equal to the concentration of the acid.
  • The pH is then equal to minus the logarithm of the concentration value.
  • Values below 7 indicate acidity which increases as the number decreases, 1 being the most acidic.
  • The pH of a solution is a measure of hydrogen ion concentration, which in turn is a measure of its acidity.
  • Pure water dissociates slightly into equal concentrations of hydrogen and hydroxyl (OH−) ions. For a neutral solution, [H+] is 10−7, or pH = 7.

Rasek [7]

Answer:

A. They are all equally related to one another.

Explanation:

In scientific terms, the evolutionary history and relationships of organisms is called phylogeny. Phylogeny describes the relationship of one organism to others, such as which organisms it is thought to have evolved from, which species it is most closely related to, and so forth.

Phylogenetic relationships provide information on shared ancestry but not necessarily on how organisms are similar or different. Scientists use a tool called a phylogenetic tree to show the evolutionary pathways and connections among organisms. A phylogenetic tree is a diagram used to reflect evolutionary relationships among organisms or groups of organisms. Scientists consider phylogenetic trees to be a hypothesis of the evolutionary past since one cannot go back to confirm the proposed relationships. In other words, a “tree of life” can be constructed to illustrate when different organisms evolved and to show the relationships among different organisms.

The right answer is blastocyst.


The blastocystic Stage of embryo development is characterized by the formation in the center of the morula (embryonic cell group) of a cavity isolated from the external environment: the blastocoele.

In embryonic development, this step precedes gastrulation.

Blastocysts are indeed composed of a hundred cells; they have the shape of a hollow sphere at the bottom of which is the mound of the "embryonic bud" from which the embryonic stem cells are derived.
