Hydroiodic acid (or hydriodic acid) is a colorless liquid. It is an aqueous solution of hydrogen iodide with the chemical formula H I. It is a strong acid, in which hydrogen iodide is ionized completely in an aqueous solution. Concentrated aqueous solutions of hydrogen iodide are usually 48% to 57% HI by mass. [2] An oxidized solution of ...
Though some outlier Hydrozoans go through a polyploid (polyp) and medusa stage, Hydroidolina, which comprises almost all hydrozoans, goes through an asexual polypoid stage where the polyp fixed to a substrate and a sexual hydroid stage varying from free-swimming medusa to a gonophore that remains attached to the polyp.

Anthoathecata, or the athecate hydroids, are an order of hydrozoans belonging to the phylum Cnidaria.A profusion of alternate scientific names exists for this long-known and heavily discussed group.
Acid–base homeostasis is the homeostatic regulation of the pH of the body's extracellular fluid (ECF). [1] The proper balance between the acids and bases (i.e. the pH) in the ECF is crucial for the normal physiology of the body—and for cellular metabolism . [ 1 ]
In the body, stores of fat are referred to as adipose tissue. In these areas, intracellular triglycerides are stored in cytoplasmic lipid droplets. When lipase enzymes are phosphorylated, they can access lipid droplets and through multiple steps of hydrolysis, breakdown triglycerides into fatty acids and glycerol. Each step of hydrolysis leads ...
Common nonvolatile acids in humans are lactic acid, phosphoric acid, sulfuric acid, acetoacetic acid, and beta-hydroxybutyric acid. Humans produce about 1–1.5 mmoles of H + per kilogram per day. [1] Most nonvolatile acids are excreted by the kidneys. Lactic acid is usually completely metabolized by the body, and is thus not excreted from the ...
Uricotelism is the excretion of excess nitrogen in the form of uric acid. [4] Uricotelic animals include insects , birds and most reptiles . Though requiring more metabolic energy to make than urea, uric acid's low toxicity and low solubility in water allow it to be concentrated into a small volume of pasty white suspension in feces, compared ...
Lactic acidosis is commonly found in people who are unwell, such as those with severe heart and/or lung disease, a severe infection with sepsis, the systemic inflammatory response syndrome due to another cause, severe physical trauma, or severe depletion of body fluids. [3]
