A forensic odontologist examines the teeth of a skull and finds no baby teeth, no wisdom teeth, scarring in the rear jawbone, no
dental diseases or tooth degeneration, and a low D-aspartic acid to L-aspartic acid ratio in the dentin. Which age range fits this skull? A.25–50 years old
The correct answer is letter B, the age range of the skull is less than 10 years old. Teeth are also a form of bone that develop within the skull. Its structure helps archaeologists determine the age of fossils that they dug up from the soil. Children lack some prominent features compared to adults because their bodies are still growing and developing into maturity.
In the matrix of mitochondria the reactions known as the citric acid or Krebs cycle produce a chemical called NADH. NADH is then used by enzymes embedded in the mitochondrial inner membrane to generate adenosine triphosphate (ATP). In ATP the energy is stored in the form of chemical bonds.

Nutrition- microorganisms are able to feed on food materials obtained from the living or dead bodies of plants or other animals. They are therefore heterotrophs.
Movement- both localized and generalized movements which results in the animal moving from one point to another. e.g., using flagella, cilia
Excretion- they lack highly specialized excretory organs but some microorganisms use contractile vacuoles for excretion which removes waste.
