The internal clock that controls many organisms' daily rhythms?

The internal clock that regulates daily rhythms in organisms is known as the circadian rhythm. This biological mechanism operates on roughly a 24-hour cycle, influencing various physiological processes such as sleep-wake patterns, hormone release, and metabolism. Circadian rhythms are governed by a group of genes and proteins that respond to environmental cues, particularly light, helping organisms adapt to their surroundings. Disruptions to this internal clock can lead to various health issues, including sleep disorders and metabolic problems.


What is the chemical name for an alarm clock?

An alarm clock typically contains various chemical components such as plastic polymers for the casing, metals for the internal mechanisms, and electronic components like circuits and batteries. There isn't a specific chemical name for an alarm clock as it is made up of a combination of different materials.


What keeps the bodys internal environment distinct from external environment?

The body's internal environment is maintained distinct from the external environment by the presence of semi-permeable cell membranes that selectively allow substances to enter or leave cells, and by homeostatic mechanisms that regulate internal conditions such as temperature, pH, and nutrient levels. Specialized organs like the liver, kidneys, and lungs also play a crucial role in filtering and maintaining the internal environment.


What regulates your feelings of sleepiness?

Your body's internal clock, known as the circadian rhythm, plays a key role in regulating feelings of sleepiness. This internal clock responds to light and darkness, signaling the brain to release hormones like melatonin to promote sleep. Other factors, such as physical activity, stress levels, and overall health, can also influence feelings of sleepiness.
