Biological processes that systematically vary over a 24-hour cycle are called circadian rhythms and are regulated by a cluster of neurons called the suprachiasmatic nucleus.
<h3>What is the circadian rhythm?</h3>
The circadian rhythm refers to the biological process regulated by the duration of a calendar day, which is common for many organisms ranging from animals to plants.
The circadian rhythms enable the maintenance of homeostatic control of physiological functions and thus perform metabolic activities.
In conclusion, biological processes that systematically vary over a 24-hour cycle are called circadian rhythms and are regulated by a cluster of neurons called the suprachiasmatic nucleus.

Some organisms may be very closely related, even though a minor genetic change caused a major morphological difference to make them look quite different. For example, chimpanzees and humans, the skulls of which are shown in Figure 12.2. 2 are very similar genetically, sharing 99 percent1 of their genes. Hope this helps! Mark brainly please!
Answer: floods, forest fires, earthquakes
Explanation:
The short term changes are those changes that affects the organisms immediately. The effect of these changes remain for short duration. Thus the environment and the living beings adapt the changes. A flood can wipe out the terrestrial ecosystem, the ecosystem will regain its original form when the water level depletes. Forest fires may kill several trees and animals in an ecosystem. But some plants and animals will sustain which can give birth to new colonies. The earthquakes affect the earth crust and biosphere. The earth crust may get stabilize again by filling up the crater and biosphere will also promote of living beings.
The name of the other substance that is more plentiful and durable that can be analyzed is the mitochondrial DNA. Nuclear DNA is located within the nucleus of eukaryotes cells and usually have two copies per cell, while mitochondria DNA is located in the mitochondria, which are organelles that convert energy from food into a form that cells can use.
Answer:
Humans have to breathe continously even when you sleep because your body needs oxygen constantly. your body does not stop working when you sleep.
