Many examples can be cited for this like blood clotting, during labor and even in ripening of fruits. Positive and negative feedback work hand in hand to maintain homeostasis in place. Positive feedback is required to enhance the system while the negative feedback is to inhibit the activity.
Answer/Explanation:
Yes, although they have similarities, meiosis and mitosis are different.
<h3>Similarities</h3>
Meiosis and mitosis are both types of cell division that results in the production of daughter cells.
They go through similar processes of prophase, metaphase, anaphase, and telophase.
<h3>Differences</h3>
However, mitosis produces two genetically identical diploid daughter cells from a diploid parent cell.
Meiosis produces four genetically different haploid cells from a diploid parent cell.
There are two rounds of cell division in meiosis, and only one round in mitosis.
