alkaline

Examples of alkaline in the following topics:

• pH, Buffers, Acids, and Bases

  • The pH of a solution indicates its acidity or basicity (alkalinity).
  • The pH scale is an inverse logarithm that ranges from 0 to 14: anything below 7.0 (ranging from 0.0 to 6.9) is acidic, and anything above 7.0 (from 7.1 to 14.0) is basic (or alkaline).
  • An example of a weak basic solution is seawater, which has a pH near 8.0, close enough to neutral that well-adapted marine organisms thrive in this alkaline environment.

• Growth of Bone

  • In this zone, lipids, glycogen, and alkaline phosphatase accumulate, causing the cartilaginous matrix to calcify.
  • The next zone is the zone of maturation and hypertrophy where lipids, glycogen, and alkaline phosphatase accumulate, causing the cartilaginous matrix to calcify.

• Male Reproductive Anatomy

  • The glands make a solution that is thick, yellowish, and alkaline.
  • As sperm are only motile in an alkaline environment, a basic pH is important to reverse the acidity of the vaginal environment.

• Nitrogenous Waste in Terrestrial Animals: The Urea Cycle

  • Dissolved in water, it is neither acidic nor alkaline.

• Hormonal Responses to Food

  • In order to neutralize the acidic chyme, a hormone called secretin stimulates the pancreas to produce alkaline bicarbonate solution and deliver it to the duodenum.

• Characteristics of Eukaryotic DNA

  • Eukaryotic DNA is packed into bundles of chromosomes, each consisting of a linear DNA molecule coiled around basic (alkaline) proteins called histones, which wind the DNA into a more compact form.

• Digestive System: Small and Large Intestines

  • The alkaline solution is rich in bicarbonate that neutralizes the acidity of chyme and acts as a buffer.

• Extremophiles and Biofilms

  • For example, a soda lake is both salty and alkaline, so organisms that live in a soda lake must be both alkaliphiles and halophiles.
