Answer: Animal pollinated plants are strong, which make them easier to be found during evidence collection but not a plentiful as wind pollen. Wind dispersed pollen produces large amounts of pollen, which makes it easier to be found in forensic science during evidence collection, but it’s harder to direct find a suspect with this type of pollen. Water dispersed pollen absolutely has to stay in water or it will degenerate. So this type of pollen doesn’t exactly help in forensic science unless a victim was drowned. 17)Describe how pollen can be used to determine if a crime occurred in the city or in the country or during the day or night. Answer: Pollen can be used to determine if a crime occurred in the city or in the country or during the day or night because country & city conditions are different. The air is more polluted in the city than in the country, which can affect plant cycles. Also, the city has a lot more sidewalks & other pavements, shaded areas and not very much fertile soil for plants to even grow. This majorly limits the types and survival of plants in that environment. Plants mostly flower in the daytime opposed to the night time because there is sun only in the daytime. This means that there is more pollen in the air during the
The study of plant remains and pollens. These items can be found in burials and and on bones. The study of plant remains helps determine the time since death or burial occurred
3. When Mendel transferred pollen from one pea plant to another, he was ___ the plants.
Round 2 = Without flowers in the ecosystem we would have lower levels of oxygen to breathe and at the same time a lot less allergies to things such as pollen but also without pollen bees would not be able to produce honey.
11.) Use a clean laboratory spatula to place small amounts of the sample from the suspects shoe in wells M,N, and O. Record the physical properties you
1. Explain why it is that evidence gained through the forensic science process is almost always considered to be circumstantial evidence.
The reason forensic evidence is so important is because it could be the cherry on top to solve a crime. Sure, there could be eyewitnesses and direct evidence,
Forensic science is helpful for three prime reasons it helps exonerate the innocent, prove the guilty, and helps identify individuals.
Forensic Detectives are the main reason most murderers are caught. Forensic Science Detectives help prevent crime by analyzing evidence. They find evidence through careful investigation of the crime scene. To become a Forensic Science Detective and make $54,400 a year, one must have a bachelor’s degree, along with on-the-job training, and be able to investigate crime scenes to find and process evidence.
Ewww! What could that awful smell be? Why it is the center of an anthropologist’s attention, of course! More specifically, it is the decaying remains of a human. Before we get too in depth though, let us start with the history. Thomas Dwight (1843-1911) is honored with the title of the Father of Forensic Anthropology in the United States. He was the first to write articles and essays on human skeletal identification. In addition, he also conducted lectures. He was dedicated to researching was to determine the physical characteristics and information of a person without using the bones from their arms or legs. He used bones in the skull to determine the victim's age at death, and the joints of longer bones to determine the gender. Since then, anthropology has grown to be so much more. Now anthropologists are able to discover a person’s height, diet, weight, age, and sex merely from deciphering their skeletal remains. This field allows scientists to not only identify victims, but it also aids in identifying if they were truly victims in the first
between a cut (an injury that is longer than deep) and a stab wound (an injury
Forensic anthropology is the physical or biological studies of a human skeleton. The purpose of a forensic anthropologist is to discover secrets hidden in bones. Forensic anthropologists are trained physical anthropologists. The difference between the two are the amount of knowledge involved in forensic anthropology. In forensic anthropology science, biology, and culture are applied to the legal process.
dy of plant fossils and the understanding the evolution of plant life and ecology of earlier eras is known as paleobotany. Paleobotanists concern with fossil records of plants and their geologic history greatly describes the main concept of paleobotany. Only a small percentage of the plants that ever lived left evidence of existence. The major plant fossils that have been discovered are mineralized wood, flowers in amber, leaf imprints in coal, or other plant life many years ago. Paleobotanists document fossil records and use this evidence to find the past evolution of plants.
1). Forensic Psychology is the application of the theories of psychology to law and the legal system. Issues of violence and its impact on individuals and/or groups delineate the main and central concerns in Forensics within the adult, juvenile, civil, and family domains. Forensic psychologists provide advice to legislators, judges, correctional officers, lawyers, and the police. They are called upon, for example, to serve as an expert witness, diagnose and treat incarcerated and probationed offenders, and screen and evaluate personnel in the law enforcement and judicial systems. Forensics encompasses a wide range of academic orientation. Synonyms for Forensic psychologists include criminal psychologist,
One piece of evidence that was used to help catch the killer, was the facial tissue under the victim 's fingernails (pg. 9). This would be biological evidence because it came from a living thing, and the person can be identified with DNA. It would also be circumstantial evidence because nobody saw the facial tissue being placed there or getting under the fingernails. This would also be classified as trace evidence because it can easily be transferred from one place to another. This evidence was used to help catch the bad guy. Since it was found on another victim thousands of miles away, it was easily linked to both murders. The facial tissue was found under the fingernails of the victim at the first crime scene. It also helps catch the bad guy
