The <em>S. salivarius</em> is chosen because it the predominant gram positive bacteria that colonizes the oral cavity shortly after birth.
<h3>What is PCR?</h3>
Polymerase chain reaction(PCR) test is a type of test that is used to identify a particular deoxyribonucleic acid of an organism.
<em>Streptococcus salivarius</em> cannot be cultured especially when the test sample is contaminated with other body normal flora.
The steps of PCR testing include the following:
- Annealing Primer to Target Sequence
- End of the First PCR Cycle
On a crime scene, the specimen that can be used for PCR testing are blood and body secretions.
PCR testing can be done on a scene with blood spills.

Explanation:
Terrestrial biomes are distinguished primarily by their predominant vegetation, and are mainly determined by temperature and rainfall. Differences in temperature or precipitation determine the types of plants that grow in a given area . Regions of similar climate and dominant plant types are called biomes.
Climate is the major factor affecting the number and diversity of plants that can grow in a terrestrial biome. Climate determines the average temperature and precipitation, the length of the growing season, and the quality of the soil, including levels of soil nutrients.
The primary factor which determines a biome is the climate. Temperature and precipitation essentially determines what kind of growing season or soil quality the terrain may have,which therefore affects the growth of plants living there.
