The answer is thermoregulation
Human is a warm blooded animal so they have to control their internal temperature. Eccrine glands is the synonym of sweat glands. Sweat has an important role to release heat as they will wet the skin, allow it to evaporate in huge area. If the sweat glands doesn't work, the person will have difficulty to dissipate heat when the body temperature increases.
Chromatin is the dna packaged around the proteins.
Biological fluids regulate pH values using buffers. This is achieved by accepting H⁺ ions when pH is low and donating H⁺ ions when pH is high.
pH is the potential of hydrogen, that gives an idea about the acidity of basicity of a solution. The value of pH ranges from 0 to 14. The pH value of 7 is considered to neutral. Any value below 7 is acidic and any value above 7 is basic.
Buffers are the solutions that resist that change in pH when any acidic or basic component is added to them. A buffer solution consists of a weak acid and its conjugate base or vice versa. The human body consists of natural buffer, which is blood.
