Meiosis is involved in the formation of the gametes of multicellular organisms.
<h3>How do multicellular organisms reproduce?</h3>
Both plants and animals reproduce by developing new individuals, through gametes or reproductive cells.
<h3>Characteristics of multicellular organisms reproduction</h3>
- Many multicellular organisms always arise from a single cell called a zygote, the result of the union of two gametes (female and male).
- The zygote subdivides rapidly throughout gestation, forming the entire body of the creature that, from its birth, begins to grow.
Therefore, multicellular organisms reproduce by means of certain types of reproductive cells that are generated and take care of building a complete new individual.

Answer;
An example of positive feedback loop is;
-When a pregnant woman begins to go into labor, the body sends hormones that increase the intensity of the labor contractions.
Explanation;
-Feedback loops are therefore the process whereby a change to the system results in an alarm which will trigger a certain result. The result will then either increase the change to the system or reduce it to bring the system back to normal.
-Feedback loops are important because they allow living organisms to maintain homeostasis (maintenance of internal environment of the body constant).
-A positive feedback loop occurs in nature when the product of a reaction leads to an increase in that reaction. It moves a system further away from the target of equilibrium, by amplifying the effects of a product or event and occurs when something needs to happen quickly.
