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:There are many advantages of immobilisation, one of which is that the enzymes can be reused – catalysing the same reaction many times. Binding the enzymes to a surface also makes them more stable and less likely to denature (lose their shape).
Explanation:
