Physiologically normal intracellular pH is most commonly between 7.0 and 7.4, though there is variability between tissues (e.g., mammalian skeletal muscle tends to have a pHi of 6.8-7.1)..Click to see full answer. People also ask, what type of bond is joining the two hydrogen atoms?The bond joining two hydrogen atoms in a hydrogen gas molecule is a classic covalent bond. The bond is easy to analyze because the hydrogen atoms only have one proton and one electron each. The electrons are in the hydrogen atom’s single electron shell, which has room for two electrons.Furthermore, what name is given to the bond between water molecules? Hydrogen bonding Also Know, are cells typically able to maintain relatively stable pH? Introduction: Cells must constantly maintain their pH in order to function properly. A slightly more basic pH (7.7) would result in convulsions and muscle spasms. As another example, the pH of cellular organelles such as lysosomes (around 5) is lower than the pH of the cytoplasm (around 7.2).How can we determine the age of fossils mastering biology?The age of fossils can sometimes be determined by radiometric dating, which is based on the constant rate of decay of radioactive isotopes. The time required for half of a radioactive isotope to decay is called the half-life of that isotope. For example, the isotope carbon-14 has a half-life of 5,730 years.
