what 4 things do we want to know about a skeleton

-sex

-height

-age

-biological ancestor

teeth are

most useful for developing a profile of a person

to determine sex u examine

the skull, pelvis, humerus and femur

to determine age and height u examine

teeth, bone growth, cranial structure and length of femur bones

to determine race u examine

the skull

ct scan

visualizes internal

x-ray

visualizes bone structure

mass spectrometer

trace elements, health

scanning electron microscope

see very small details

dna analysis

samples of bones

bone is made up of

calcium

things that can be mistaken for bone:

wood, metals, sheetrock, plaster

how to tell if something is a bone

shape, structure, texture, chemical composition
