Final answer:
The statement in the question is false, as metabolic rate is influenced by factors such as diet and thyroid function, contradicting the claim that no cause-and-effect relationship exists between posture and metabolism.
Step-by-step explanation:
True or false: No cause-and-effect relationship has been established between posture and metabolism. Based on the information provided, this statement would seem to be false. Metabolic rate can be affected by several factors including diet and thyroid activity. For instance, a balanced diet can result in excess energy being stored in the body, thus increasing the rate of metabolic reactions. Thyroid hormones also play a significant role in metabolism; a patient with an overactive thyroid will tend to have a higher metabolism, while a patient with an underactive thyroid will have a lower metabolism. Therefore, while the statement doesn’t directly relate to posture, the provided information suggests that metabolism can be influenced by various physiological factors.
A. False. There is a cause-and-effect relationship between posture and metabolism. Posture can affect the efficiency of metabolic reactions in the body. For example, sitting or standing with proper posture can promote better circulation, which can enhance metabolism. Conversely, slouching or being sedentary for long periods can lead to slower metabolic rate.
