Summary Introduction

To review:

The given blank space in the statement, “In the emergency department, even though the patient’s PaCO2 was very high (539 mm Hg), the COHb level of 47 percent (enhanced……; impaired…….) the hemoglobin’s ability to carry oxygen”.

Introduction:

The measurement of the partial pressure of carbon dioxide (PaCO2) and carboxyhemoglobin (COHb) in blood is important to test the function of the lungs and the risk of any future lung diseases. The level of high carbon dioxide and carbon monoxide will cause a decrease inflow of oxygen into the blood through the alveoli, which leads to less binding of oxygen with the hemoglobin molecule. This condition could cause conditions like anemia.

1.) Community Diversity: The brown and orange line represent two different plant communities. a. Which color represents the community with a higher species richness? b. Which color represents the community with a higher species evenness? Relative abundance 0.1 0.04 0.001 2 4 6 8 10 12 14 16 18 20 22 24 Rank abundance c. What is the maximum value of the Simpson's diversity index (remember, Simpson's index is D = p², Simpson's diversity index is 1-D)? d. If the Simpson's diversity index equals 1, what does that mean about the number of species and their relative abundance within community being assessed?
