The results only give an indication about precision; they give no indication of accuracy. Accuracy is a measure of how close the results are to a known literature value; however‚ because a known molarity for the hydrochloric acid is not known‚ a measure of accuracy cannot be made. In contrast‚ a measure of precision can be made using the results. Precision refers to how close a set of results are to each other. In this lab‚ the percent relative average deviation can be used as an indicator of preciseness

their bubble and did not offer help to their co-workers. They also found that when the number of RNs on the floor was increased more teamwork occurred. They also found when the staff is mixed with more NAs then RNs there is less teamwork that occurs‚ however when there are more RNs on the floor than NAs teamwork is increased. The findings were related back to the framework of the study. This study revealed that hospital bed size‚ type of employee and staffing all effect teamwork. The findings of the

Explain why increasing the extracellular K+ causes the membrane potential to change to a less negative value. 5. Discuss the relative permeability of the membrane to Na+ and to K+ in a resting neuron. 6. Discuss how a change in Na+ or K+ conductance would affect the resting membrane potential. ACTIVITY

The CULTURE OF BAHALA NA Of the 1‚000 entries from the Internet‚ the first meaning of “Bahala na” that I was able to extract is “Come/Happen what may” or “Whatever will be will be.” Let us analyze a song composed by Heber Bartolome (2001) entitled “Bahala Na.” (The translation into English on the right column.) The song captures the Bahala na attitude of the Filipino. A Filipina worker goes abroad to seek greener pastures and

the different colony count observed. Materials and Methods Initially‚ two plates were gathered one was nutrient agar (NA) and the other was sabouraud dextrose agar (SDA). Then gathered two packs of cotton tipped applicators. Then a magic marker was used to label each plate making quadrants numbering each one. Also the name and date was written on the edge of the plate. In the NA plate Whitney swabbed her left index finger in the first quadrant. Then washed her hands. In the second quadrant Whitney
