<span>There are many theories as to how multi-cellular life formed. The development of multi cellular life has occurred independently at least 46 times. It has been proposed that a minor genetic change in a molecule guanylate kinase protein-interaction domain (GKP-ID) may have allowed life to go from single to multi-cellular. It is also Possible a mutation of the DNA responsible for the mechanism of cell-division lead to the development of multi cellular life.</span>

An ice age caused Earth’s oceans to cool, which killed many of the unicellular organisms. When the ice age ended and Earth warmed, the continents broke apart. This event allowed the shallow seas to cover the continents. The warming of Earth, accompanied by the seas covering the land, created the proper conditions for multicellular organisms to form.

muminat

Answer:

Homeostasis

Explanation:

Homeostasis is a mechanism of the body which involves negative feedback loops that helps the body to maintain a stable internal environment when there is an external or internal change.

An example of homeostasis in the human body is the regulation of the internal temperature of the body. When there is a change in the normal body temperature, for example, if your temperature drops sharply below 37 degrees Celsius, homeostasis kicks off in the body to maintain the normal body temperature. Homeostasis uses thermoregulation mechanism which triggers shivering to raise the body temperature in an attempt to return it back to normal.

Homeostasis also makes it possible for the body to maintain the balance of water and other substances in the body like calcium in our body. For example, when the calcium level drops below normal level, the parathyroid gland secretes hormone which helps in the increasing of blood calcium levels.  

Homeostasis s a essential mechanism that helps keeps the body in a balance and functional state.
