The hydronium ion is an oxonium ion whose chemical formula is H3O + or H + (aq). It is found in the solid, gaseous or liquid state (protonation of a molecule of water).
The concentration of hydronium ion is directly linked to the pH of the tea (or any solution) by this equation.:
C° (hydronium) = 10^(-pH)
if the pH of the tea is 6 for example, than:
C° (hydronium) = 10^(-pH) = 10^(-6).
Answer:
White blood cells (WBCs) are specialized to respond to antigen and produce antibodies as well as undergo phagocytosis in response to toxic stimuli.
WBCs are part of immune system and there are five different kinds with specialized features.
In order to make a cell model, it is best to use a muscle cell and a nerve cell or neuron: there are pronounced structural differences and those are present throughout animal kingdom.
Lower animals ( such as insects, worms etc. ) have different immune system, however, they do have typical neuron and a muscle cell/skin cell (fibroblast). Such cell models are likely to be easy, distinct and bring you good grades without going through much complication and confusions of various organ systems and animal mod
Explanation:
The correct answer is T helper cells. <span>T helper cells are important because they have the ability to stimulate other cells to kill the foreign particles (viruses, bacteria, fungi, parasites).T helper cells help other cells in the immune response by recognizing foreign antigens and by secreting cytokines that then activate T and B cells.</span>
<span>The group includes their common ancestor but also the seeded descendants of that same ancestor.</span>
