A very important part of any scientific discipline is being able to communicate technical information in a clear, concise, and academically rigorous manner. This includes being able to research information that is relevant to a topic and write about what you learned in a way that is easily understood by a wide variety of readers. […]

Chemical bonds are the foundation of chemistry. Please explain several types of bonds (at least two).

Select ONE of the CBRN (Chemical***) categories, then pick ONE particular agent(Sarin Gas) from that category and based on our readings this term, place yourself in the role of a terrorist and offer your perspective of how a terrorist event could be conducted in your hometown(Tampa,Fl), then provide your perspective on how to prevent such an attack and support your work by a variety of academic material to give your opinion more validity. Your paper must be at a minimum of 5 pages (the Title and Reference pages do not count towards the minimum limit). Scholarly and credible references should be used. A good rule of thumb is at least 2 scholarly sources per page of content. Type in Times New Roman, 12 point and double space.

Write an essay explaining the five main branches of chemistry: 1. organic chemistry, 2. inorganic chemistry, 3. analytical chemistry, 4. physical chemistry, and 5. biochemistry Minimum 600 words

Do the analysis of penicillin and beta-hemolytic strep. Describe the disease and also complications symptoms of disease beta-hemolytic strep. How it can be treated with the medication of penicillin or another way can be treated.“

 Lecture Question: Is BH3 polar or nonpolar? 

Explain the importance of the biological buffer systems and gas relationships in our bodies.   Background This week we will study solids, liquids, gases, and acids and bases. The gas laws play an important role in respiratory care. Titrations are important in medicine as pharmacists and anesthesiologists, to name a couple of examples, use this method to determine the amount of medicine a patient needs. A healthy individual’s fluids must maintain a certain pH in order to function properly.   Prompt Choose one of these topics (gas laws, titrations, pH levels) and provide an example of how they are used in medicine. Discuss the importance of these principles in the treatment of a patient. Some examples are carbon dioxide playing a role in maintaining pH, the kidney’s role in helping to maintain blood pH, altitude sickness, how gas laws play a part in syringes and injections and determining medication dosage through titration, to name just a few.

Need to write a 300-word report about the structure and biochemistry of the stratum corneum and relate it to the function of the barrier. There is no introduction and conclusion included in this writing so you crucially need to get straight to the point and be concise as it is only limited to 300 words. I have also attached a file on the marking criteria you need to follow to aim for good grades. As you can see, the first and second ‘content and ideas’ rubric is crucial to follow as it is worth at least 30 points.  There are two main parts to this writing: – Comprehensively outline the structure and show a sophisticated understanding of the biochemistry of the stratum corneum and explain why this is a good barrier (always relate everything you are saying to the barrier function). (This part is 60% of what is explained in this writing, so focus more on this more than the other which is written below). – Explain how the skin treatment ‘crystal microdermabrasion’ disrupts/impairs the barrier and how it recovers following this procedure. (again, do not write anything about the procedure process, get straight to the point). (Could be a couple of sentences or a very small paragraph). Everything explained has to be related back to the function of the barrier (if it doesn’t, then don’t include it in this writing). Relate at all times. Everything said needs to be explained in-depth and in detail. (Why and how) But as scientifically as possible, do not put unnecessary words as you need to think about the word count.   in regards to the marking criteria rubric, do not worry too much about the ‘referencing’ and ‘presentation’. Do not use images. and you need at least 15-20 references from peer-reviewed journal articles. No less than 15. They need to be relevant; the peer-reviewed journal articles have to be no less than 5 years old. Because I attend an Australian school, those are the rules of good research. Good research is needed!! As this is 300 words, 25 words more than the general order requirement, I will pay extra once completed and if this is outstanding quality, I will give a good tip.

 How vitamins and minerals/trace elements affect health/human body? Determine chemical names and/or chemical formula for diatomic or simple polyatomic compounds and draw a Lewis structure, construct a molecular geometry and determine the polarity for a covalent compound. (This is what he is looking for in the paper).
