On behalf of the Eliel Arrey Team, I would like to welcome all the returning students and tutors to another great academic year.  This year we plan on adding more classes and more material to support your science needs more than we ever have.  Over the summer we were able to expand our service parameters to more classes and adopt new technology to better our delivery.  More professors have recognized our efforts and are recommending us to more students.  We are very pleased to be able to do such non-profit work.  Our joy is great and our satisfaction is full, but there is still much more work to be done on our part.
Currently we are expanding our servers to support the volume, hence at this time new students are unable to subscribe to receive our free elite member services (more practice tests, mp3s, videos, etc).  However, it is projected that by September 20th, our servers will be all up and running for new member sign ups.  We are expecting over 1000 new members between September 20 and November 2nd.  Please be patient with us and we do apologize for this delay. 

Thank you for using our services.

Yours,

E.  Arrey

President

So we have been getting a lot of emails about our newly posted Medical School Admission Guide online.
And since most of the students that use this website are pre-medical students at different levels

Questions requested by students for further review of material on S.I. practice exam.

Question# 10 on (mini exam 40,41)

10) A mouse uses ______ energy per kilogram of body weight compared to an elephant, therefore in smaller animals the rate of energy use per cell is _______ than that in larger animals.

                A)less, more

                B) less, greater

                C) less, less

                D) more, less

                E) more, greater


 the correct answer is E.
smaller organisms use more energy per kilogram of body weight unlike larger organisms.
Hence, smaller organisms use greater energy per individual cell than larger organisms.

Reasons being because they have less cells to perform the same metabolic duties a
larger organism performs.  For example, not all your cells are directly involved in digestion. Right?
You have specialized organs (ex stomach, liver, etc) that perform that action.

A smaller or single celled organism has just one cell (or a few) that perform all their actions (reproduction,
digestion, etc) so the cellular metabolic energy usage and production will be higher than that of a larger
organism.

Hope that works, let me know
if I can help some more.

Question # 27 (from S.I. Exam review)

27) Ventricular tachycardia (v tach) is a dangerous condition of elevated heart rate, about 200 beats per minute.  Which of the following best explains why v tach is such a deathly condition if normal rhythm is not quickly restored?

                A) The heart fills with blood during systole, so faster heart beat means less time there is for blood to enter the heart.  A faster heart beat means diminishing returns in terms of amount of blood supplied to the body.

                B) Damage to the SA node comes with aging, hence the v tach condition can only be found in the older population.

                C) During period of rest or exercise the autonomic nervous system controls heart rate.  Hence a v tach syndrome is due to a nervous disorder.

                D) The v tach condition is evidence of cardiac input disorder.

                E) The heart fills with blood during diastole, so faster heart beat means less time there is for blood to enter the heart.  A heart with v tach cannot properly fill with blood and paradoxically stops pumping blood.

the correct answer is E.

Why is A not correct? Faster heart beat means diminishing returns in terms of blood....that is all correct, except that blood does not enter the heart during systole.

Question # 35 from S.I. Exam 2 review

35) A sphygmomanometers measure the gauge pressure in the systemic circulation, which is the pressure above atmospheric pressure (760 mmHg at sea level).  At what component of the circulatory circuit would one expect to detect the largest drop in blood pressure?

                A) Arteries

                B) Veins

                C) Venules

                D) Capillaries

                E) Arterioles

The correct answer is E.
If you can recall blood pressure is highest in
arteries right.  And it is lowest in the capillaries.
Hence that high blood pressure leaving the aorta
undergoes its largest drop when it reaches the arterioles,
so that by the time it gets to the capillaries, its blood
pressure is lowest, allowing for exchange of substances.

Thanks

Questions # 26 - 32 (from S.I. practice exam)

The mechanism of Antimicrobial burst.

Usually, since an antimicrobial burst is an
innate ability, it is triggered in anticipation
of infection.  When the epithelial cells of
the skin are damaged during a sporting
event by bruises, or something of that
nature. 

It's triggered similar to how the blood clot
mechanism works.  Usually spontaneous when
blood pressure seems to drop around a
particular superficial vein/vessel.

Hope this helped.

Questions #8, 22, 39 & 43 from S.I. exam 2 review

8. which of the following have influence on metabolic rate.
E. all of the above

22. HIV pt. w/o T-lymphocytes, would be most susceptible to A. Viral infections
or
B. to bacterial infections? I remember Pneumonia and TB (viral and bacterial)?
A, viral infections. T-cells are vital for protection against viral infections, while B cells which are much larger and cannot cross the cell membrane generally fight bacterial infections.

39. osmotic pressure on venous side of capillary beds drops below hydrostatic pressure-
C. the pH of the interstitial fluids increase????
B, fluids will tend to accumulate.
Osmotic pressure higher than hydrostatic pressure on the venous side is what allows for substances to diffuse across blood plasma into interstitial fluids. Whenever osmotic pressure drops lower than hydrostatic pressure at the venous end of capillary beds, fluids don't diffuse enough across and tends to coagulate blood returning to the heart. Clinically diagnosed as pulmonary thromboembolism.

43. Compared with the interstitial fluid that bathes active muscle cells, blood reaching these cells in arteries has a
B. higher PCO2?
A, higher PO2 (partial pressure of oxygen). Muscles part of systemic system, so arteries taken blood to these muscles has a higher partial pressure of oxygen versus Carbon dioxide.

Quickly there are a lot of myths about the medical school admission process.  Lets just get some of them exposed so that we can make sure we're all on the same page. :)

COMMON MYTHS ABOUT MEDICAL SCHOOL ADMISSION by the MedicalSchoolAdmissionGuide.com
Myth # 1: I need perfect undergraduate grades and a very high MCAT score to get into medical school.

Myth # 2: Medical schools prefer students who are right out of college. An admission committee will not take my life experience into account.

Myth # 3: Only applicants who attend a "big" school get accepted into medical school.

Myth # 4: The most important part of the application process is my grades.

Myth # 5: Medical school admission committees have a set standard for accepting an applicant.

Myth # 6: The admission criteria for most medical schools is publicly available.

The good news? ALL OF THESE MYTHS ARE FALSE.
Recently we have added the Extra Mile service and in that we discuss the real 'reality' of the medical school admission process.
Click here to go to that part of our website.

The great Dr. Frederick once gave me the best recipe to master Anatomy and Physiology.  She didn't provide me with an easy route, but with a guaranteed success route...one that was very difficult and required a great deal of self discipline.  Recently Dr. Frederick made a perfect combination of all the techniques that were once told by word of mouth from student to student.  Now she shares with college students, HOW to Study for Anatomy & Physiology. (click on 'Read More" below)

Finally, in succeeding as a Biology student, one needs to know how to approach a biology exam and also how to control the feelings that follow failure.  Dr. Frederick, PhD., breaks down how to approach exams and how to stay motivated even when failures arise. 
Dr. Frederick has always told her students that "Your grade is a number, but you are not. The exams are usually difficult but they are not a test of your intelligence."
Be sure to take some notes as we deliver this last volume of "How to Succeed In Biology"
Enjoy.

A continuation of How to Succeed in biology.  Excerpts from college Biology professor, Dr. Frederick, PhD.
Part 2 of 3 contains How to Study.  An overview of the Do's and Don'ts when mastering Biology.
Enjoy.

This was lectured to me by Professor, Dr Frederick when I was a freshman in college.  She laid the ground work for my success as she taught us Biology (the course) and How to Succeed In Biology (the Degree). 
I was quite inspired as always and I felt the need to share this with all students who may be seeking the same
guidance that I once sought.  With Dr. Frederick's permission, I have posted this online into series of success tips for students all around.
Enjoy, take lots of good notes. 

Why Dr. Frederick? 
Dr. Frederick has a tremendous life story.  One of trials, perseverance, and success.  She has made it to where she is today because she endured and never gave up.  She knows exactly what most students are going through now in their college life and has great advices that apply to the masses.  She shares with us some things you can't afford not to know, such as how to get a letter of recommendation, how to master biology, and a simple trick on how to Ace it! 

I will recommend her to any student who is planning on taking College (Freshman) biology or Anatomy & Physiology (A&P).  She is a great teacher.

Coming soon --  Learning Organic chemistry is difficult.  It is a science course that demands a higher level of reasoning. A special guest, PhD, shares with us 'How to learn Organic Chemistry'.  Stay tuned.

Before we get into the meat of it all. When we do simple water tests, we usually just focus a few matrices. One of them is the TDS reading. TDS stands for totally dissolved substances.

What does a TDS meter report? It measures the combined content of all inorganic and organic substances contained in a liquid (in parts per million, ppm). Could be anything really; agricultural and residential runoff, leaching of soil contamination and point source water pollution discharge from industrial or sewage treatment plants.

The most common chemical constituents are calcium, phosphates, nitrates, sodium, potassium and chloride. More exotic, harmful elements of TDS are pesticides arising from surface runoff.

Generally, a high TDS levels generally indicate hard water, which can cause scale buildup in pipes, valves, and filters that reduces performance and adds to system maintenance costs. (down side to hard water)

The TDS readings we have been picking up in the local areas are way beyond and above that U.S. EPA maximum contamination level of 500ppm. Recently in the Red Oak, TX area I have personally come in contact with families drinking water with a TDS reading of 897ppm. And that should be a boil alert.

However, if you consider the fact that pure water only should have a TDS reading between 0-15ppm (our personal standard is 0-5ppm) then it becomes clear that many families are taking in a lot of impurities. And I will invite you to do the same. Whenever you get your water tested, get a TDS reading and whenever you get a water treatment system have another reading done to see how improvement has been done.

So with that said, the TDS reading of an average Ozarka bottled water was 26ppm (7 bottles were tested). Some bottles were higher and others were as low as 23ppm. We previously published an article that addressed dangers every consumer should be aware of and of those dangers, we stressed a lot the source of the bottled water and the quality. There are no regulations that require bottled water companies such as Ozarka, Nestle, etc, to report the make up of their bottled water. The 23ppm avg. could imply anything to a consumer.

Once again, we've discussed why it is important for the consumer to purify his/her own water from home. Not only is it cheaper, there is greater deal of control and protection.

More of our water tests and municipal water has been compiled by my team and is available to all who seek more information about the water we use everyday.
