1. Comparing and Contrasting Word a) **Manner of Death and Cause of Death** The cause of death is the immediate cause of a person's death, such as a heart attack or kidney failure. The manner of death is the means by which someone dies, such as natural, accidental, homicide, suicide, and undetermined. The similarity is that both are used to describe and classify a person's death. The main difference is that the cause of death relates to what happened that cause the death of a person, and the manner is death is a categorical term to show what group is falls into. b) **Cause of Death and Mechanism of Death** The cause of death is the immediate reason for a person's death (such as heart attack, kidney failure). The mechanism of death is specific body failure that leads to death. Cause of death is more of what someone died from and mechanism of death is why/how someone dies. The mechanism of death is what leads to the cause of death. The mechanism of death is the change in the body that lead to the persons deaths. The mechanism of death can be things like loss of blood from a gun shot or if they have a heart a attack it is called heart failure. Cause of Death is more basic. c) **Larva and Pupa** Larva is the immature form of an animal that undergoes metamorphosis. Pupa is the stage in an insect's life cycle when the larva forms a capsule around itself and changes into its adult form. Larva is the form of an insect before it turns to a pupa. They are different stages of metamorphosis. d) **Rigor Mortis and Livor Mortis** Rigor mortis is the stiffening of the skeletal muscles after death. Livor mortis is the pooling of the blood in tissues after death, resulting in a reddish color to the skin. The similarity is that they both classify conditions of the body after death, and both are used to help forensic examiners discover the time and date of a death. The difference is that rigor mortis deals with muscles, and livor mortis deals with blood. e) **Decomposition and Autolysis** Decomposition is the process of rotting and breaking down. Autolysis is the spontaneous break-down of cells as they self-digest. Both refer to what happens to a body after death. Decomposition is a much slower process and Autolysis. Autolysis is much faster and is self-digest compared to decomposition, which is much slower.

2. The explanation of the deer's enlarged abdomen is relatively simple especially as its laying on it side dead. The swollen abdomen is a part of the bodies natural decomposition after four days of being dead. What happens after two days is insects begin crawling in the body and laying eggs. The swelling is a result of the carbon dioxide build up in the stomach.

3. If a person were killed in the country, there would be plenty of evidence to prove that he had been there. First of all, there would've been fibers on his clothes that couldn't be found in New York City, such as hay or certain types of produce. There could be hairs from certian types of animals, such as cows, sheep, or pigs. Also, there would be pollen in his lungs and stomach that could've come only from outside the city. There are different types of pollen in urban and rural areas, and the medical examiner would be able to prove it. The conditions of his body, regarding to rigor mortis, algor mortis, and livor mortis, could prove that he had been dead long enough in order to make such a lengthy transition. If the man had been dead only a short amount of time, it would've been impossible to move him from the country to the city, but if he had been dead for at least an hour, it would be possible that the body could've been moved after death.

4. I do agree with this estimation because as it states earlier in the article, if you can only see rigor mortis in the face and neck, then it has just started and it has only been just over 2 hours. If it were 15 hours then there would be more rigor mortis in the body, not just in the face.

5. The first insects to arrive are called Blowflies and they are attracted to the body because of two gasses that the body lets off when starting to decompose. These gasses are called putrescine and cadaverene. Once the decomposition continues more insects will come such as tiny wasps who lay their eggs on maggots that are already on the body. I assume that the decomposition of a squirrel is on par with the decomposition of a human body.
