How sound affects bacterial growth

Pinker’s metaphorical expression for music was “auditory cheesecake”, explaining that he considered this function “useless[as a biological adaptation]” (Pinker 1997, p.528). Perhaps avid listeners comfort feed their minds with acoustic cheesecake, but musical knowledge presents the impact of such sweetness goes far beyond just licking the spoon. Extracting Pinker’s perspective, this essay will discuss whether music is valuable in the survival of humans. Arguments will be derived from brain imaging findings to examine its biological predisposition, adaptionist view to seek out its evolutionary status and whether the environment is responsible for demoting music.

One area of interest for researchers is the healing power of music through its vibrations and rhythms. Music has a beat and a pattern that our bodies pick up on and connect with; our bodies identify the rhythm, and it is sent directly “to motor nerves in our spinal

Not only does music affect thought, but it also benefits health. Students usually study in quiet, relaxed surroundings while listening to serene music. Classical music can steady a fast heartbeat and a slower heartbeat induces relaxation. Exercise plays a critical role in maintaining good health, and relaxing music can be favorable to this. Music reduces muscle tension, resulting in a better work out. Scientists performed controlled studies using adult males who were around twenty-five years old. Blood samples were taken before and after treadmill running. The experiment found that with the presence of music, “heart rate, blood pressure, and lactate secretion in the brain were significantly lower” . The results proved that music

6. The disks in the 0.00% solution were transferred to an agar plate held next to the blue flame using the sterilized tweezers. Excess disinfectant was removed from the disks by wiping on the side of the well of the spotting tile. When the 5 disks were positioned (refer to Figure 1 below) the lid was replaced and sticky taped down. A label was added indicating the concentration of disinfectant.

14. Use the same loop and technique to spread the same cell suspension (+) on the LB+AMP agar plates. Dispose of the sterile loop in a beaker of germicide.

For each part of the lab (I, II, III) identify the control (if any), the independent variable, and the dependent variable.

The auditory system is the most abundant in the human body, which is why listening to music can affect people. Many have said that music makes them feel better; some say that listening to music helps them learn; others, it motivates. While reading in the internet we found many interesting stories of how music has helped stroke patients learn how to talk again, how patients with Alzheimer could regain some of their memories, and that premature babies could gain weight while listening to music. When we read this, we couldn't help but wonder how can all of this happen with music?

One could continue to go on and on with so many historical examples of the therapeutic use of music on the human body. But from the humble beginnings of music, the art of composing has continued to grow drastically over time. Today there is much research and data proving scientifically that music is even more recognized for its benefits and even detriment on the physiological and psychological systems of the body (Cook). Research recently, after about 250 years of separation, is once again uniting medicine, health psychology and

6. After allowing time for each sample to cool, they are separated into small tin trays.

-Do not dispose of any materials unless method is specified in instructions or by the teacher. -Solutions should be handled with care. Clean-up: -Materials used in this lab should be disposed of in the waste container. -The waste container should be in the fume hood to prevent too much exposure. -All apparatus used in the lab should be thoroughly cleaned with soap and water.

Music is composed of sounds intertwined with melody and rhythm that can have powerful effects on a person. It can help people focus on tasks or calm the mind. Research has shown that music has beneficial effects on the mind, body, and health of a person. A journal article by Rastogi, Solanki, and Zafar (2013) refers, on the contrary, to:

A new study found that the brains of people with epilepsy react differently to the sound of music. Researchers hope the findings could lead to new therapies to prevent seizures.

Step 1. Prepare a slide with the positive culture results by transferring the sample to be examined onto a drop of suspension medium such as distilled water using a sterile inoculation loop.

5. After taking out the first petri dish, drop some iodine solution over the samples. Measure the diameter of the circle formed around the sample and record. 6. Repeat steps 4-5 for the rest of the petri dishes, changing the temperature to 55 degrees, 60 degrees, 65 degrees, and 70

Music elicits an emotional and cognitive response in all who listen to it. It is powerful at the individual level because “it can induce multiple responses – physiological, movement, mood, emotional, cognitive, and behavioral” (Francis, 2008,
