What purpose does defining the area of investigation in excavation of skeletal remains serve?

Biology
1 answer:
meriva2 years ago
6 0

The Forensic Biologist's primary job and responsibility is to provide information leading to the identity of the person, the cause of death, and the time since death.

purpose of defining the area of investigation in excavation of skeletal remains serve for :

  • Age Determination: It is possible to estimate a person's age based on their bones. If the entire skull is available, the scientist's task becomes easier because tooth eruption and fusion of skull sutures are important characteristics on which an opinion on the age can be given with a high degree of certainty.
  • Determination of Cause and Manner of Death: In order to provide an opinion on the cause and manner of death, the forensic biologist closely examines each bone, its pieces, and fragments to look for signs of injuries that could have resulted in death. In many homicide cases, an examination of the skull reveals a variety of fracture patterns, including bullet holes, which helps to determine the cause of death.
<h3>What is the importance of exhumation in criminal investigation?</h3>

Exhumation is essential in criminal investigations. It aids in the identification of the perpetrators in many mysterious murder cases. To seal the skeletal remains in order to send them first for post-mortem examination and then to the Forensic Science Laboratory for additional examinations.

Are humans a dead end host for streptococcus pneumonia? If yes please explain why. Thank you!
zlopas [31]

Answer:

No, because Pneumonia can be transferred from one person to another.

Explanation:

Because humans are the only natural host for S. pneumoniae, our data suggest that the CbpA-mediated recruitment of complement FH may contribute to host tropism of this pathogen. A person can spread the germs that cause pneumonia when he or she coughs and expels the bacterial or viral infections that caused the disease. The droplets containing the virus or bacteria can land on a common surface, such as a table, telephone, or computer. Anyone can get pneumococcal disease, it occurs more frequently in infants, young children, the elderly or in people with serious medical conditions such as chronic lung, heart or kidney disease. Others at risk include alcoholics, diabetics, people with weakened immune systems and those without a spleen.

Have the best day ever! :D

Design an experiment to answer the question, what is the effect of caffeine on the rate of mitosis in frog eggs? Label: hypothes
s2008m [1.1K]

Answer:

Explanation:

Null Hypothesis: Their will be no effect of the caffeine on the mitosis.

Hypothesis: Caffeine will inhibit the SHSY5Y cell division.

Dependent variable: Various concentration of the caffein compound.

Independent Variable: temperatures of the experimental condition. If their will be any effect of the temperature in mitosis then it will also affect the mitosis of control cells.

Experimental design.

Culture SHSY5Y neuronal cell line in the T-75 culture flask in CO2 incubator at 37 degree celsius. Next day, add cells from T-75 flask in the 24 well plate and allow cells to adhere to the well by incubating plate in CO2 incubator at 37 degree celsius. Add the compound caffeine at different concentration (say 1 microgram, 2 microgram, 3 microgram, 4 microgram) and incubate the plate for 24 hour. Determine the mitotic cells by following assay.

Assay to determine mitotic cell.

The reagent succinimidyl ester of carboxyfluorescein diacetate (CFSE) binds to cytoplasmic proteins. it is fluroscent reagent. And when cell divide due to mitosis, cytoplasm will also divide and hence, the protein which stained with the CFSE reagent will also goes in the daughter cell. Then, the fluorescence of the stained cells can be read on the plate reader.

Prepare the graph of the fluorescence values (Y-axis) verses different concentrations of the caffein (X-axis) and determine the slop of curve to know the rate of mitosis.<u> </u>

<u>Following test and control samples will be used for the assay.</u>

1. SHSY5Y cell line with added caffeine. It is test sample.

2. SHSY5Y cell line added with buffer. This important to know behaviour of cells under experimental conditions.

3. SHSY5Y cell line with solvent used to dissolve compound caffeine. It is important to know the toxicity or any effect of solvent on the mitosis.

How can genetic mutations increase the variation in a population over time?
hichkok12 [17]

Answer:

The flow of individuals in and out of a population introduces new alleles and increases genetic variation within that population. Mutations are changes to an organism's DNA that create diversity within a population by introducing new alleles.
