Answer:

Base

Explanation:

Deoxyribonucleic acid, DNA, is one of the four major biomolecules in living organisms. It is a polymer made up of monomers called NUCLEOTIDES. The nucleotides that make up a DNA molecule is composed of three substances namely: Sugar (deoxyribose), nitrogenous base, and a phosphate group.

However, among these three components of the nucleotide monomer, NITROGENOUS BASE is the only portion that is not the same in every DNA molecule. There are four nitrogenous bases in nature viz: Adenine, Guanine, Cytosine and Thymine. These four bases can be alternated in a DNA molecule.

Note that, phosphate group and deoxyribose sugar are constant in every DNA.

How do scientists use the kinetic theory of matter?
Keith_Richards [23]

The energy of moving matter is called kinetic energy. Scientists think that the particles of all matter are in constant motion. In other words, the particles of matter have kinetic energy. The theory that all matter consists of constantly moving particles is called the kinetic theory of matter. 

  • If particles do not have enough kinetic energy to overcome the force of attraction between them, matter exists as a solid.
  • If particles have enough kinetic energy to partly overcome the force of attraction between them, matter exists as a liquid.
  • If particles have enough kinetic energy to completely overcome the force of attraction between them, matter exists as a gas.

List three conditions that would alter the activity of an enzyme. be specific with your explanation.
anyanavicka [17]
Three conditions (or inhibitors) will stop the enzyme's reaction from taking place. If another substance attaches to the site first the the reaction will not take place because the substrate can no longer attach to the active site. Conditions within the cell like temperature and acidity will also inhibit the reaction because it will change the shape of the active site which is very specific for the substrate that needs to attach to it. The enzyme will then become ineffective.
