Three ways scientists can determine the age of a deceased person.

• Age of teeth, decay of tissue, and length of leg bone.
• length of the leg and arm bones; whether the epiphyses and shafts of long bones are connected with cartilage or fused with bone; presence or absence of teeth. 
• Length of bones, missing teeth,
  color of the soil.
• Missing teeth, missing bones, and color of the soil stain.

One skeleton feature that differs between males and females.

• A female's chin is more square than a male/
• Females have a smaller sciatic notch than males.
• A female’s skull usually has a larger back ridge
•  Males have a smaller sciatic notch than females.

To determine ancestry, what methods do anthropologists use?

• skull conditions and soil stains.
•  observation, laboratory testing, and precise measurements.
• Observation and precise measurements.
• Precise measurements only.

What happens when a body decays?

• Microbes consume dead tissue to extract nutrients.
• Muscles and ligaments hold the bones in place.
• Muscles contract and swell.
• Microbes consume bones causing them to flake.

What causes pieces of bone to flake?

• Bones expand when exposed to moisture and contract when they dry out, causing flecks of bones to flake off.
• When they come in contact with air.
• When they are exposed to salt water.
• Bones expand when exposed to air and will burst into flakes.

How could the scientists tell that the body had been wrapped in a shroud?

• The shroud was still there.
• By the position of the leg bones.
• By the color of the soil stain.
