You and some of your friends are discussing the topic of biological rhythms, and one of your friends says that the fact that they are endogenous means that external stimuli are not important to them, and another of your friends says that the fact that environmental cues entrain and modulate the rhythms means they are not really endogenous at all. How would you respond to each of your friends

Endogenous nature of them has to remove the external stimuli and doing so reveals clearly that they persist. The fact that external cues can entrain and modulate don't negate the fact fundamental rhythm is endogenous.

Explanation:

Biological rhythms are regarded or considered to be the natural cycle of change in the body. That is , the repeating cycles of activity that occur in most or all of the living organisms.

It is believed to be internal and considered to be controlled  by internal body clock, but may still respond to environmental cycles.

In this case, i will let my friends know that, biological rhythms  are actually endogenous, despite the fact that they might respond to external or environmental stimuli or cycles. Meaning that , they can still persist even when the external stimuli are not there.

Response to stimuli is for adaptation

Explanation:

Biological Rhythms are the body's internal clock. This is a master clock that keeps the body on a pattern of time. This may be days as the circadian rhythm or months as the female menstrual cycle. While it is indeed true that the body is designed and regulated to follow this pattern, elasticity for changes allows for adaptation to the specific surroundings and weather and hormonal changes. For example, the circadian rhythm controls the sleep/wake cycle. If a person were to move to another continent maybe from the West to the far East, the day/night pattern will be disrupted for a short period of time but will once again adjust. Although the biological rhythms are somewhat dependent on the external stimuli, the master clock has a way to regulate itself for optimal adaptation and it will work in the way that it was designed to do.
