The whole research cannot be provided but for instance a example for the statement " The environment and human health are interrelated". the environmental factors lead to lung and respiratory diseases in humans.
One of the most significant organs that are exposed to environmental toxins is the lung. The negative impacts of environmental agents will depend on how susceptible a person is to their influence.In particular to ozone (O3), nitrogen dioxide (NO2), particulate matter (PM), and sulfur dioxide as sources of air pollution (SO2) are some of the main toxins that cause lung problems. The ciliary cells are first altered by O3 intake. O3 is a very potent oxidant because it makes epithelial cells more permeable and reduces mucociliary clearance. Epithelial cells and alveolar macrophages are hampered in their ability to operate by NO2, a less strong and less reactive oxidant pollutant.In conclusion, air pollution interferes with both general and specialized lung defenses, making it easier for pulmonary disorders like asthma, allergies, and asthmatic acute episodes to develop.

A 75-year-old male with long-standing hypertension and angina due to coronary heart disease presents with ankle edema, nocturia, increased shortness of breath with activity, and a chronic nonproductive cough. He has a past history of smoking two packs per day and is an ex-alcoholic. His blood pressure is 170/80 and his heart rate is 100. Electrocardiography and chest radiography indicate the presence of left ventricular hypertrophy.
A. Relate the presence of uncontrolled hypertension and coronary artery disease to the development of heart failure in this man.
B. Explain the significance of left ventricular hypertrophy in terms of both a compensatory mechanism and as a pathologic mechanism in the progression of heart failure.
C. Explain the management and treatment for this diagnosis.
Left ventricular hypertrophy increases the chance of sudden death. Studies have shown that the problem increases the risk of developing some diseases, such as heart failure, stroke, coronary heart disease and even sudden death.
A. How does hypertension cause heart failure?In summary, heart failure can occur in the natural history of patients with hypertension, as a result of the action of a wide set of adaptive mechanisms triggered by the persistent increase in ventricular afterload, resulting in diastolic or systolic dysfunction.
B. What is the significance of left ventricular hypertrophy in terms of a compensatory mechanism and a pathological mechanism in the progression of heart failure?The term cardiac hypertrophy refers to increased myocardial mass. It is an adaptive response to a physiological or pathological overload. This adaptation occurs as a response of the heart to an overload of work and can be classified as concentric or eccentric.
C. Explain the management and treatment for this diagnosis.Treatment depends on the underlying cause and may involve medication or surgery. Left ventricular hypertrophy caused by aortic valve stenosis may require surgery to repair the narrowed valve or to replace it with an artificial valve.
With this information, we can conclude that left ventricular hypertrophy increases the chance of sudden death. Studies have shown that the problem increases the risk of developing some diseases, such as heart failure, stroke, coronary heart disease and even sudden death.

Question 6
What role did the bile salts play in Part 3 of this exercise? How do these results correlate with where bile salts occur in the human body?
Answer:
Ans:They are produced in the liver, directly from cholesterol. Bile salts are important in solubilizing dietary fats in the watery environment of the small intestine.it elements toxins it breakdown the fats and it absorbe important vitamin of your food.
Explanation:
The body's ability to digest fat depends on bile salts. They work as emulsifiers, dissolving lipids into smaller droplets to facilitate enzyme digestion.
After a meal, bile salts are produced in the liver, stored in the gallbladder, and then released into the small intestine. Their presence in bile makes it possible to break down and effectively absorb dietary fats. Some bile salts are recycled by the body after aiding in digestion, thereby saving energy. Bile salts contribute to the body's food intake and normal metabolic processes by helping to ensure efficient fat digestion and absorption.

You will write an argumentative essay to the “Bill and Melinda Gates Foundation” to convince them to support the use of genetically modified organisms in agricultural development and support your team in developing the transgenic strain, knowing that this organization can provide the needed funding for your project.
The word count of your essay should be between 300 and 750.
Your essay should include at least 10 keywords from table 2.
Your essay will discuss how the new strain of the genetically modified plant will contribute to eradicating disease by using appropriate scientific methods that take into consideration any possible adverse health effects and environmental concerns (such as new potential allergies, herbicide resistant weeds, and biodiversity issues for replacing other strains). It will also discuss why community acceptance of the new strain is important as a sustainable long-term solution as opposed to supplements or other food additives.
The purpose of your essay is to establish a stance on the urgency of the new strain issue by providing reasons and supporting evidence. When you’re writing a persuasive essay, you need more than just an opinion to make your voice heard. Even the strongest stance won’t be compelling if it’s not structured properly and reinforced with solid reasoning and evidence. Your essay needs to be well written and should include the following 4 elements:
1. Introductory paragraph:
The first paragraph of your essay should outline the topic, provide background information necessary to understand your argument, outline the evidence you will present and states your thesis.
2. The thesis statement:
This part of your essay is a concise, one-sentence summary of your main point and claim.
3. Body paragraph:
You will explain the reasons why you support your thesis. You can discuss more than one idea or piece of evidence that clearly and concisely explain why the reader should agree with your position.
This is where you will back up your claims with examples, research, statistics, studies, and scientific evidence based on your knowledge in genetics and your answers in the graphic organizer.
Address opposing points of view and disprove them or explain why you disagree with them. Presenting facts and considering the topic from every angle adds credibility and will help you gain the reader’s trust.
4. Conclusion:
One paragraph that restates your thesis and summarizes all of the arguments made in your body paragraphs. Rather than introducing new facts or more arguments, a good conclusion will appeal to a reader’s emotions. In some cases, writers will use a personal anecdote explaining how the topic personally affects them.
Genetically modified organisms can help to alleviate hunger around the world by increasing crop yields.
What are Genetically modified organisms?Genetically modified organisms are organisms whose genetic material (DNA) has been altered in the laboratory by using genetic engineering.
Genetically modified crops can be resistant to different types of biotic and abiotic stressful conditions and thus increase crop yield.
Supporting evidence regarding the use of GMOs is based on empirical statistics about how these food helped to alleviate global hunger, especially in developing countries.
An essay about GMOs should ideally include information on genetic engineering techniques used in transgenesis.
Transgenesis refers to the genetic engineering techniques aimed at developing organisms carrying genes of others species. These techniques include, among others, the use of the CRISPR-Cas9 genome editing system, DNA recombinant strategies and vector expression constructs (e.g., viral recombinant vectors).
A thesis statement is a well-sustained question that can be tested (either confirmed or rejected) by information obtained using the scientific method.
GMOs have been shown to the safe since empirical scientific evidence revealed that genetically modified crops such as Bt maize do not cause allergies or diseases in human beings.
Moreover, GMOs can help to alleviate hunger around the world by increasing crop yields.
In conclusion, it is possible to state that GMOs might be beneficial when they are approved and released by proper governmental agencies such as the US Federal agency of Food and Drug Administration (FDA).
