Discuss how pathological and morphological changes within bone might help a forensic anthropologist determine both a cause and a theoretical timeline of death.

The body can tell us many things about the life of a person. Lab analysis on human blood can reveal insight into diet, lifestyle, propensity for disease, as well as hundreds of years of ancestral lineage.

In death, the body is as equally telling as the body systems and tissues have distinct characteristics and norms. Factors such as the cause and time of death, sex, and age can be determined through a post-mortem examination.

Instructions:

In this case study, assume the role of a forensic anthropologist that must examine a skeleton found in a shallow grave in a state park. You will research and simulate the actual procedures used within a forensics lab to determine the age, sex and height of a skeleton, as well as learn to….

Discuss how the act of pupil dilation can be accomplished by the physical act of hearing music (non-visual stimuli).

Estimated time to complete: 2 hours

As noted by Gingras et al (2015), emotional stimulation has been known to lead to pupil dilation and contraction.  For dilation of the pupils to occur during the listening of music, the special senses must work in conjunction with the autonomic nervous system (ANS). In addition, for this study to be physiological fact, the special senses and the ANS must also work collectively with the peripheral nervous system (PNS) and central nervous systems (CNS).

Instructions:

Read the attached article, The Eye is Listening: Music-Induced Arousal and Individual Differences Predict Pupillary Responses. During the reading, take notes and consider the following: The role of each neurological system (ANS,….

 What would happen if the tubing with the yellow band was placed in a beaker of distilled water? 

Data Tables and Post-Lab Questions

Table 6: Sucrose Concentration vs. Tubing Permeability

Post-Lab Questions

 

1. For each of the tubing pieces, identify whether the solution inside was hypotonic, hypertonic, or isotonic in comparison to the beaker solution it was placed in.

2. Which tubing increased the most in volume? Why?

3. What does this tell you about the relative tonicity between the contents of the tubing and the solution in the beaker?

4.  What would happen if the tubing with the yellow band was placed in a beaker of distilled water?

5. Osmosis is how excess salts that accumulate in cells are transferred to the blood stream so they can be removed from the body. Explain how this process works in terms of tonicity.

6. How is….

Why do cells that lack cell cycle control exhibit karyotypes that look physically different than cells with normal cell cycle control?

EXPERIMENT 5: THE IMPORTANCE OF CELL CYCLE CONTROL Data

1.

3.

4.

5.

 

Post-Lab Questions

1. Record your hypothesis from Step 1 here.

2. What do your results indicate about cell cycle control?

3. Suppose a person developed a mutation in a somatic cell that diminishes the performance of the body’s natural cell cycle control proteins. This mutation resulted in cancer but was effectively treated with a cocktail of cancer-fighting techniques. Is it possible for this person’s future children to inherit this cancer causing mutation? Why or why not?

4. Why do cells that lack cell cycle control exhibit karyotypes that look physically different than cells with normal cell cycle control?

5. What are HeLa cells? Why are HeLa cells appropriate for this experiment?

6. Research….

Part I – Emergency Mrs. Helms came in through the front door of her house with an armful of groceries. She put the bag down on the kitchen counter and called to her husband. “Herb, I’m home! Are you ready for lunch?” She didn’t get an answer, so she walked to the living room and found Mr. Helms lying on the fl oor. “Herb! Are you okay?” she asked as she grabbed his shoulder. Mr. Helms responded weakly while clutching his chest. Mrs. Helms frantically called 911. It only took EMS a few minutes to arrive and the paramedics transported Mr. Helms to the hospital. Upon admission to the….
