Write an essay describing the crime.
After your topic has been approved by your instructor write between 600 and 1200 words detailing the crime. You should include your name(s) at the top followed by a title for your paper. Put the link or a citation of the source information at the end. If you do not have a link, then you should cite the source using the following
format:
article author(s) [if provided]. year. article title.Miami Herald. date. page(s). our name(s), title and citations do not count towards the total word count. Add the total word count at the top right as follows: “total words: ____.”
When writing the essay, do the following:
1. Include a very brief introduction with background relevant to understanding the crime.
2. This section is the most important part of your paper. Spend a significant amount of time discussing the
forensic evidence
used in the investigation & prosecution of the crime. This can be evidence used to convict or exonerate a defendant or simply used in the investigation especially if the crime is still unsolved. If there are multiple pieces of relevant evidence, focus on one or at most two main pieces. You are better off discussing one piece in detail than two or three too flippantly.
a. Discuss the theory behind the evidence. For example, how is it that we can identify someone’s height
based on the length of bones or how we can use blood spatter to determine the source of blood and its
speed? What is the science behind those things and how was it relevant to this case?
b. You should also discuss how the evidence applied directly to this case.
3. Briefly summarize the evidence as it related to the outcome of the case. If there were some problems you identified (e.g., the evidence was applied incorrectly or too broadly), this would be the time to explain that.

The stomach is a muscular hollow organ. It takes in food from the food pipe, mixes it and starts breaking it down. The pre-digested food is then passed on to the small intestine in small portions.

Review the color-flagged text on your report, fix any issues, and resubmit again before the deadline (this assignment is set to unlimited submissions). Note that less than 10% of your work should contain direct quotes. Outside of simple spelling and grammar checks, no form of generative AI may be used to complete your work.
Email me with any questions! Assignment Instructions: The topic of your Course Project will be any medical disease or condition of the body (e.g., arthritis is too broad; choose one specific type such as osteoarthritis, rheumatoid, etc.). Choose ONLY one medical disease or condition that interests you, as this will be the topic used for all Course Project steps and assessments throughout the term.
Autism Spectrum Disorder – Centers for Disease Control and Prevention (CDC)
My topic and resources:
For my course project, I chose to focus on Autism Spectrum Disorder (ASD). The reason I am choosing this condition is due to its profound impact on many individuals and families, including a close friend of mine who has a child with autism. I have also worked as a Behavioral Therapist in ABA. I am deeply interested in understanding the complexities of ASD, including its diagnosis, management, and support strategies, to better appreciate the challenges faced by those affected and to contribute to raising awareness and support within the community.
The article I have chosen as a source of information is from the Centers for Disease Control and Prevention (CDC) website titled “Autism Spectrum Disorder: Overview, Risk Factors, and Treatment.” The CDC offers a comprehensive overview of autism, including prevalence statistics, risk factors, early signs, and recommended treatments.
The CDC website is an authoritative and credible source of academically and scientifically reliable information. As a leading national public health institute in the United States, the CDC plays a crucial role in gathering and disseminating accurate health information to the public.
The articles on the CDC website are written and reviewed by subject matter experts, including medical doctors, clinical psychologists, and public health professionals. For instance, Dr. Stuart Shapira, a renowned expert in developmental disabilities, frequently contributes to the CDC’s autism-related content. Secondly, the CDC’s articles frequently reference peer-reviewed research studies, national health statistics, and clinical guidelines from reputable organizations such as the American Academy of Pediatrics and the National Institutes of Health (NIH). Each claim is supported by specific citations that link to scientific literature and data. Finally, the CDC is a respected government agency renowned for its role in public health research and information dissemination. It is known for maintaining high standards of transparency and accuracy in the information it provides.
B. Based on the evidence provided, I believe this source is a credible source overall. All three pieces of evidence support the reliability and accuracy of the information. The fact that the CDC employs subject matter experts with advanced degrees in relevant fields ensures that the content is created and reviewed by individuals with a deep understanding of autism. This adds a high level of credibility to the information. Additionally, the use of peer-reviewed studies and reputable sources as references means the data has undergone thorough scientific scrutiny. The CDC’s dedication to transparency and frequent updates further enhances the trustworthiness of the information, demonstrating a commitment to providing the most current and accurate data available. Therefore, the CDC’s comprehensive approach to disseminating health information makes it a highly reliable and credible source for research on autism.

Hemoglobin is a protein found in red blood cells (RBCs) that transports oxygen throughout the body. The hemoglobin protein consists of four polypeptide chains: two alpha chains and two beta chains. Sickle cell disease (also called sickle cell anemia) is caused by a genetic mutation in the DNA sequence that codes for the beta chain of the hemoglobin protein. The gene is located on chromosome 11. The mutation causes an amino acid substitution, replacing glutamic acid with valine. Due to this change in amino acid sequence, the hemoglobin tends to precipitate (or clump together) within the RBC after releasing its oxygen. This clumping causes the RBC to assume an abnormal “sickled” shape.
Individuals who are homozygous for the normal hemoglobin allele (HbA) receive a normal hemoglobin allele from each parent and are designated AA. People who are homozygous for normal hemoglobin do not have any sickled RBCs. Individuals who receive one normal hemoglobin allele from one parent and one mutant hemoglobin, or sickle cell allele (HbS), from the other parent are heterozygous and are said to have sickle cell trait. Their genotype is Aa. Heterozygous individuals produce both normal and mutant hemoglobin proteins. These individuals do not have sickle cell disease, and most of their RBCs are normal. However, due to having one copy of the sickle cell allele, these individuals do manifest some sickling of their RBCs in low-oxygen environments. People with sickle cell disease are homozygous for the sickle cell allele (aa genotype); they have received one copy of the mutant hemoglobin allele from each parent. The resulting abnormal, sickle-shaped RBCs in these people block blood flow in blood vessels, causing pain, serious infections, and organ damage.
This exercise is an opportunity to practice identifying genotypes and phenotypes. Record your answers on the Word version of these questions. You will submit this as part of your lab submission. The Hemoglobin Beta gene is located on chromosome 11, an autosome.

The essay should be double spaced with illustrations as evidence
The paper should be formatted in the form of a scientific argument
and referenced according to APA Style. Research is encouraged
and should be from a variety of sources EXCEPT from Wikipedia
Your essay topic
Your task is to write about Psilocybe cubensis (fungus category) and explain in why it is worth saving. 
Cryptic means something that is hidden or not well known. So
please avoid things such as Pandas, polar bears and other cute
things. Choose something that you would not necessarily think the
public would look for. Describe your organism in terms of anatomy
and morphology, evolutionary position and ecological necessity. It
must be a compelling argument and cannot just be “coz its cute
and fluffy and we all go gaga over it” You should try to relate it to
ecological position, biomes populations and what would happen if
this animal/plant/fungus suddenly disappeared. 
When writing the essay you just need to state the  scientific name of the plant once and then you can refer to it as just the first word EXAMPLE: Oryza sativa and then referer to this as Oryza only. 
Make sure the format of the word is proper in ittalics. 
The paper should try to outline the following (if applicable): 
Taxonomy: What is the scientific name of the organism? Common
names? Family? Any thing related to it of which we’ve heard? 
Overview of the organism, the cultural/ historical/geographical
connections such as where it originated, how they used it in the
past, how people use it today… History and effect on civilisation or
the effect of civilisation on it 
Morphology (anatomy): What does the organism look like?
PICTURES!
Cellular and biochemical characteristics of the organism disease
caused /cured. What portion specifically is used? Give chemical
name and structural diagram (picture). 
You should provide a enough data supporting your conclusions. You SHOULD use as many pictures as you can to help illustrate
and support or defend your analysis. Using APA style formatting for
your references you will also use as many current relevant scientific
sources as you can to establish a valid analysis. if you are unsure of
how to do this please ask. Think about cells, behaviour, evolution,
ecology and geography, genetics and conservation. 
It should be a comprehensive report. It is, after all, equivalent to a 3
month research report! The report should include relevant
background data from peer reviewed references such as journals
and books. you may use the internet as long as it is from a reputable
site. You should reference materials and methods and include a
graphical representation. You should find some logical way of
organizing them so the reader can follow them smoothly. A reference
list would be good Unless you use them in text it is just a list of books
that may or may not have anything to do with the topic
Make sure to use journals, peer reviewed references, books all that are credible and all cictation in APA format 
make sure CHATGPT free and turnitin free 
I have attched an example of a paper make sure this paper of mine is done properly.

This is a UC’s personal insight question essay
Describe how you have taken advantage of a significant educational opportunity or worked to overcome an educational barrier you have faced. Let’s establish one fundamental thing: this prompt asks that you write about an education opportunity OR barrier – not both! So you’ve got to make a choice. Before doing so, let me define what this PIQ’s important terms even mean.
UC defines an “educational opportunity” as “anything that has added value to your educational experience and better prepared you for college.” They provide a few examples: “honors or enrichment program[s], enrollment in an academy that’s geared toward an occupation or major, or taking advanced courses that interest you.” I know I always benefit from a little more specificity, so let me provide a few more concrete examples of what an educational opportunity might look like:
A summer science program during which you created a research project in molecular biology
An internship with a state legislator that allowed you to pursue your interests in political science/law
Dual enrollment at a community college so you can take more advanced math courses than what’s offered at your high school
To be honest, writing about an educational opportunity for PIQ #4 is easier if you already feel confident about your choice of major. This is because you can really demonstrate your interest in and dedication to your intended area of study. Of course, you can still write a good opportunity essay if you’re undeclared, but if you’re sure about your major and you have a suitable opportunity in mind, responding to this PIQ is a great choice.
Before getting into more detail about the educational opportunity option, let me first clarify this prompt’s second part: the option to write about an “educational barrier.” In their Guide for Freshman Applicants worksheet UC defines educational barriers as “any barriers or challenges related to school and/or your schoolwork.” In other words, an educational barrier is something that interfered with your learning and performance at school.
Here’s a list of examples that would qualify as educational barriers:
Your school didn’t offer a particular AP you wanted to take
You had to take ESL classes before or alongside taking regular courses
You struggled with a learning difference like ADD, ADHD, or dyslexia
You had to care for your younger siblings over the summer, so you couldn’t take part in a particular summer enrichment program you were interested in
That list is NOT exhaustive; even if none of the above apply to you, you can definitely still write a strong barrier essay. However, a couple of topics I notably excluded from the list are failing an exam and/or not doing well in a particular class because you didn’t do your homework, ditched classes, zoned out during lectures, etc. Think of educational barriers as things that were outside of your control, not a result of your own behaviors. What does have to do with your behavior is the way you overcame the barrier you encountered. If you choose to write about an educational barrier for this PIQ, its focus should be how you faced the problem and what you learned in the process. 
My struggle was having a language barrier + a shy personality so it was really hard to overcome the language barrier. I tried as hard as possible to get myself out of my comfort zone but it wasnt easy.
