Final Answer:
The given statement "when ethyl alcohol depresses brain function, is it displayed as bad judgment" is True answer because ethyl alcohol, or ethanol, is a central nervous system depressant. Thus the correct option is A. True.
Step-by-step explanation:
When ethyl alcohol depresses brain function, it indeed results in impaired judgment. Ethyl alcohol, or ethanol, is a central nervous system depressant that affects neurotransmitter activity in the brain. It primarily enhances the inhibitory effects of the neurotransmitter gamma-aminobutyric acid (GABA), leading to a decrease in brain activity. As a consequence, cognitive functions, including decision-making and judgment, are significantly impaired.
The mechanism behind this involves the suppression of excitatory signals in the brain. Neurons normally communicate through a balance of excitatory and inhibitory signals. Ethyl alcohol disrupts this balance by enhancing inhibitory signals, causing a general slowdown in neural activity. This manifests as symptoms such as slowed reaction times, decreased coordination, and impaired decision-making. These effects can contribute to what is commonly referred to as "bad judgment."
In essence, the impact of ethyl alcohol on brain function is not subjective; it is supported by neurobiological changes that result in observable behavioral consequences. This understanding is crucial in recognizing the risks associated with alcohol consumption and its potential impact on cognitive abilities. Therefore, the statement that when ethyl alcohol depresses brain function, it is displayed as bad judgment is indeed true.
Thus, the given statement "when ethyl alcohol depresses brain function, is it displayed as bad judgment" is True. Thus the correct option is A. True.
