The changes in the following mentioned parameters as a result of the upper airway obstruction and subsequent ventilation–perfusion ratio. A. PAO 2: ________ _ increased; ________ decreased; _ remained the same B. PACO 2 : ____ _ increased; ________ decreased; _ remained the same C. PCO 2 : _ increased; __ decreased; _ remained the same D. PC CO2 : increased; __ decreased; _ remained the same E. pH: ________ _ increased; ______ decreased; _ remained the same Introduction: Upper airway obstruction is a clinical condition characterized by the presence of blockage in the upper airway that includes the trachea, the larynx, or the voice box, and the throat. Blockage in the upper airway prevents the body from getting enough oxygen. Upper airway obstruction leads to the diminishing of pulmonary ventilation.

Question

Imagine you are a botanist. Below are characteristics of a never-before described plant species recently identified as part of the ‘All Taxa Biodiversity Inventory’ (ATBI). Field Notes: Specimen collected from shaded area along stream in South Cumberland State Park (Grundy County, TN). Laboratory Analysis: Body: Large leaves emerging from underground rhizome. Size: 63 cm Chromosomal Analysis: Plant body is diploid—chromosome number of 44. Lignin test: Positive Cuticle: Present Leaves: Present—large with branched veins. Underside has sori (containing haploid spores). Roots: Present—branch from the inside. Stem: Present—vascular tissue (xylem & phloem) present. Life History: Diploid sporophyte dominant generation. Haploid spores germinate into heart-shaped, haploid, gametophyte. Water required for fertilization; no seed is produced. Diploid zygote develops into sporophyte. Explain which domain, kingdom and phylum you believe this plant should be classified…
