entomology
| Question | Answer |
|---|---|
| Third stage of a fly's life cycle | Pupa |
| Third stage of decomposition; will have large maggot masses and noticeable odor | decay |
| Type of animal that is often used to simulate a human body in forensic entomological experiments | pig |
| The shedding of an exoskeleton that occurs as a larva or adult insect grows | molting |
| Term that refers to the larval stage of a fly | maggot |
| Data related to the temperature and precipitation in an area where a crime scene is located | weather |
| Order that includes beetles | coleoptera |
| Order that includes flies | diptera |
| study of insects | entomology |
| Female flies will lay their eggs near body openings or | Wounds |
| The time between the death and the discovery of a body; called the postmortem interval | PMI |
| Last stage of a fly's life cycle | adult |
| Second stage of a fly's life cycle | larva |
| Last stage of decomposition in which most of the flesh is gone | Post decay |
| Stage of decomposition that begins at the moment of death | Fresh |
| Second stage of decomposition in which the body becomes inflated due to the production of gases from bacteria | Bloated |
| Type of metamorphosis that has four stages | complete |
| First stage of a fly's life cycle | egg |
| Explain how a forensic entomologist would use fly larva to estimate the PMI | 1st -collect maggots 2nd-Identify species 3rd-Determine length of maggots 4th-use evidence |
| What does a physical anthropologist investigate | bone |
| What four things do we want to know about a skeleton | sex, age, stature, race |
| What bones are most useful for developing a profile of a person? Explain how they are used. | skull. age, sex, and race |
| What bones can provide clues for each of the following items? | Sex-skull age and stature -humorous, femur race -skull |
| What other information can we learn from bones? | DNA, recent injuries, and cause of death |
| What techniques or tools did the scientist use to find the body? | probes |
| What is "disturbed soil"? What might it indicate? | soil that has been mixed around; something being buried |
| How did they narrow down the areas to investigate? | They used the probes to flag down the areas w/soft soil |
| Did they find a body? | no |
| What information do they provide for law enforcement agencies? | identification, how they were killed, DNA |
| How many skeletons do they have in their collection? | 30,000 |
| What do they learn about a skeleton from each tool? | CT Scan, X-Ray, Mass spectrometer, Scanning electron microscope, DNA Analysis |
