I believe the correct answer is A. Diffusion happens continually until equilibrium is attained. It moves from a higher concentration to a lower concentration. The driving force of such process is the concentration gradient between two systems. In order to be in equilibrium, the concentration at any point of a mixture should be equal.
The Earth's lithosphere is 100km while astehnosphere is 660km so this statement stands true.
Other statements are false like Earth’s mantle is thinner than its oceanic crust as Earth’s mantle is around 3k km while its oceanic crust is just 5km.
Also, Earth’s outer core is thicker than its mantle and Earth’s continental crust is thicker than its lithosphere is false as well.
Answer:
Streptococcus mutans
Explanation:
Tooth decay results from metabolic activity of the microbes which live on teeth.
A layer of carbohydrates and the proteins forms when the teeth which is clean come into contact with the saliva.
Certain microbes are attracted to these biomolecular food source and thus form a biofilm which is known as plaque.
<u>Streptococcus mutans is the most important cariogenic species. </u>
When a disaccharide sugar from the food, is broken down by the bacteria in mouth, the units glucose and the fructose are produced. Glucose is used to make the dextran, which is part of extracellular matrix of biofilm. Fructose is fermented which produces organic acids which dissolve minerals of tooth. The plaque biofilm overtime become thick and calcify eventually.
