Week 7: Forensic Entomology and Biological Evidence (Virtual Lab)
The lab consists of two parts, entomology and Pollen. Upload assignments from Entomology
Overview
: Insects infesting habitats, spreading disease, contaminating food products, and helping to determine time of death are some aspects of Entomology that could wind up in court. In most cases, forensic experts would be used in court to testify on Entomological issues. However, the collection of the information and evidence is often done by forensic scientists working as crime scene investigators or
lab scientists. Insect Biology, Insect Identification, and Forensic Entomology are core courses for the Forensic Science Degree CSI Track at the University of Nebraska-Lincoln. This lab is designed to give all students a basic introduction to insects as forensic evidence.
Insects have six legs, usually two pair of wings except for flies which have one pair, three body regions (head, thorax, abdomen), and often compound eyes.
Flies are one of the most common insects to visit a dead body. Larvae of flies, often called maggots, have
distinguishing anatomical features.
The spiracles (breathing holes on the rear of a maggot or on the sides of adult insects) and other features can help to identify flies and other insects. See https://shire.science.uq.edu.au/bb/parasitology/maggots/maggot.html
for an interactive maggot
identification key. During lab you will learn to identify insect body parts and anatomical features, and you will learn to use a dichotomous key to help identify insects.
Erin Bauer, an Entomologist with the UNL Entomology Department, conducts the labs (this semester done virtually). In this virtual lab you will examine various maggots. You will also learn to use a
dichotomous key to identify other forensically important insects.

Use a dichotomous key
to identify insects in the photos provided to you below. A dichotomous key is a tool that can help you identity organisms based primarily upon physical characteristics. Dichotomous keys consist of a series of choices that lead to the correct identification. Several keys are available in Canvas to help you. You only need to identify to Order.

Question 14 of 190
FINAL - Science
The question is based on the following passage.
M ClassMarker-Test
Which statement does the passage support?
Although most animals and some plants detect and respond to sound vibrations, the precise
sensitivity that we call hearing is rare in the living world. It is highly developed only in birds
and mammals, and the same operational system applies in all vertebrate auditory systems.
Sound waves cause a liquid within the organism's auditory apparatus to vibrate. These
vibrations are picked up by receptors that transmit signals to nerve cells. These cells then
communicate the sound to the brain. Humans can hear vibrational frequencies of 20 to
20,000 cycles per second; cats respond to frequencies of up to 50,000 cycles per second;
and porpoises and bats pick up frequencies of 100,000 cycles per second.
OA. Ears are damaged by high frequencies.
OB. Humans have the best hearing of all animals.

Medical Law & Ethics
A
24 24
Instructions
Medical laws and ethics are crucial in this field. Laws are implemented not only to ensure proper medical services are provided and
to secure patient's rights, but also to protect the provider and the staff. Though laws can be subject to change, they still cover a vast
variety of situations set forth for everyone involved. An example of what the laws cover would be providing accurate and
appropriate medical care, professionalism, communication, and security of patient information, who owns and has access to patient
medical records, and to whom and where reports can be submitted if medical malpractice is suspected.
For this discussion assignment, you will be given two scenarios; you should base your answer on your understanding and research of
medical laws and ethics. Your initial post should be 75-100 words. Once you submit…
