Excess cortisol could result in: an alkaline blood pH . high blood glucose levels. increased parasympathetic nervous system activation. low blood pressure.

To analyze the effects of excess cortisol, let's break down the options provided: 1. **Alkaline blood pH**: Cortisol is a glucocorticoid hormone that typically does not cause an alkaline blood pH. Instead, it can lead to metabolic changes that may result in acidosis. 2. **High blood glucose levels**: Cortisol promotes gluconeogenesis, which is the production of glucose from non-carbohydrate sources. Therefore, excess cortisol is indeed associated with high blood glucose levels. 3. **Increased parasympathetic nervous system activation**: Cortisol is primarily associated with the sympathetic nervous system and the body's stress response. It does not increase parasympathetic activation; rather, it can inhibit it. 4. **Low blood pressure**: Cortisol generally helps to maintain blood pressure by enhancing the effects of catecholamines (like adrenaline) and promoting sodium retention. Therefore, excess cortisol is more likely to lead to high blood pressure rather than low blood pressure. Based on this analysis, the correct effect of excess cortisol from the options provided is: - **High blood glucose levels.**
