Connor et al. (2022) published an article in Tree Physiology (https://doi.org/10.1093/treephys/tpac150). Based on the data presented in Figure 5, evaluate the hypothesis that elevated atmospheric CO₂ can reduce the negative effects of drought on woody plant growth. In your response: Describe the overall trends in biomass across the CO₂ and water treatments. Determine whether all four species respond similarly to elevated CO₂ and explain your reasoning using evidence from the figure. Propose a physiological mechanism that could explain why elevated CO₂ influences plant growth under water-stressed conditions. Predict how these results could affect the future abundance of woody plants in rangeland ecosystems under climate change scenarios. Figure 5 Tissue specific biomass proportion for each of the woody species (Cornus drummondii, Gleditsia triacanthos, Juniperus osteosperma, Rhus glabra) based on the experimental treatments.

A nurse is caring for a 72-year-old postoperative patient who reports nausea and requests medication. The patient is drowsy after anesthesia and has the following assessment findings: BP: 108/64 mmHg HR: 88 bpm RR: 12 breaths/min SpO₂: 94% on room air Current IV fluids: Lactated Ringer’s at 75 mL/hr Orders: Ondansetron 4 mg IV PRN every 6 hours for nausea Promethazine 12.5 mg IV PRN every 6 hours for nausea The nurse decides to administer ondansetron instead of promethazine. Which clinical reasoning best supports the nurse’s decision?
