While strep throat, which is caused by bacteria, can also lead to a sore throat, only about 30% of kids and 10% of adults with a sore throat have strep, according to the Centers for Disease ...
The pH range is commonly given as zero to 14, but a pH value can be less than 0 for very concentrated strong acids or greater than 14 for very concentrated strong bases. [2] The pH scale is traceable to a set of standard solutions whose pH is established by international agreement. [3]
A universal indicator is a pH indicator made of a solution of several compounds that exhibit various smooth colour changes over a wide range pH values to indicate the acidity or alkalinity of solutions. A universal indicator can be in paper form or present in a form of a solution. [1]
In and of themselves, pH indicators are usually weak acids or weak bases. The general reaction scheme of acidic pH indicators in aqueous solutions can be formulated as: HInd (aq) + H 2 O (l) ⇌ H 3 O + (aq) + Ind − (aq) where, "HInd" is the acidic form and "Ind −" is the conjugate base of the indicator. Vice versa for basic pH indicators ...
Although it is unpleasant, fever rarely rises to a dangerous level even if untreated. [105] Damage to the brain generally does not occur until temperatures reach 40.0 °C (104.0 °F), and it is rare for an untreated fever to exceed 40.6 °C (105.1 °F). [ 106 ]
For many species, potassium-deficient plants are more susceptible to frost damage and certain diseases than plants with adequate potassium levels. Increased disease resistance associated with adequate potassium levels indicates that potassium has roles in providing disease resistance, and increasing the potassium levels of deficient plants have ...
Apples. The original source of sweetness for many of the early settlers in the United States, the sugar from an apple comes with a healthy dose of fiber.
Periodic fever, aphthous stomatitis, pharyngitis and adenitis syndrome is a medical condition, typically occurring in young children, in which high fever occurs periodically at intervals of about 3–5 weeks, frequently accompanied by aphthous-like ulcers, pharyngitis and cervical adenitis (cervical lymphadenopathy). The syndrome was described ...
