Which of the following biological activities have circadian rhythm except: a) sleep-awake cycle, b) blood pressure, c) body temperature, d) sodium level in blood? All of the following are limbic areas except: a) hypothalamus, b) premotor area, c) amygdala, d) hippocampus? All of the following are limbic areas except: a) hypothalamus, b) primary area, c) amygdala, d) hippocampus?
Understand the Problem
The question is asking to identify which biological activities do not have a circadian rhythm and which areas are not part of the limbic system. It presents multiple-choice options for each question.
Answer
Sodium level in blood; Premotor area; Primary area.
Sodium level in blood; Premotor area; Primary area.
Answer for screen readers
Sodium level in blood; Premotor area; Primary area.
More Information
Circadian rhythms influence regular body functions, but sodium levels are regulated more by physiological needs rather than time of day. The limbic system is involved with emotion and memory; areas like the premotor and primary areas are not part of this system.
Tips
A common mistake is confusing sodium regulation with other regulated processes like blood pressure. Remember, limbic areas are mostly involved with emotions and memories, not motor functions.
