A tuning fork is placed against the forehead of a patient. The sound is loudest in the left ear. What can you determine about the patient’s hearing? What is happening in the left ear and the right ear? Begin your Internet search with the National Institute of Deafness and Other Communication Disorders website. Also, search for deafness, hearing, and cochlea.
Be detailed in your explanation and support your answer with facts
from your textbook, research, and articles from scholarly journals.
In addition, remember to add references in APA format to your posts
to avoid plagiarism. Review of APA format:

The GI tract is lined by a series of tissues in an organized way. Describe the four layers of the GI tract (5 points). Using the stomach as a model organ, discuss the various cell types that exist, their function, and the communication that exists amongst the various cell types in order to accomplish its digestive function. Be sure to explain the types of communication that are present (e.g. autocrine, paracrine, endocrine etc.) (10 points)

Weight Loss surgery is becoming more and more popular as a treatment method for dangerously obese individuals. Listed below are three examples of individuals who may be a candidate for bariatric surgery.
Would you recommend bariatric surgery to any of these individuals? Make sure you explain why you would or why you wouldn’t recommend surgery for each person.
Person 1: A 75-year-old male, 5’9”, 290 lbs. He has always carried extra weight throughout his life, but in recent years has gained significant amounts of weight. He is diabetic and has a family history of heart disease.
Person 2: A 16-year-old female, 5’3”, 250 lbs. Raised in a family
with poor dietary habits, she has been overweight and obese her
entire life. Despite many, many failed diet attempts, she continues
to gain weight each year.
Person 3: A 45-year-old male, 6’ 1”, 325 lbs. He was a football
player in college, but in the years since, all of the muscle mass
he used to carry has turned into fat. He is still mobile but isn’t
able to do the physical activities he wants to do.
