Cell division begins with <u>Interphase</u>, which signals the start of the cell division process. Here, the DNA in the cell duplicates to form chromosomes.
The next phase is the <u>Prophase</u> where the chromosomes begin condensing and becoming more compacted and tightly wound. The mitotic spindle also starts forming at the edges of the cell. This would later on drive cell division by elongating the cell.
After prophase comes the <u>Metaphase</u>, where the pairs of chromosomes are pulled towards the opposite ends of the cell, causing them to be temporarily lined up at the center of the cell.
The pulling force pulls the chromosomes further towards the edge of the elongated cells in the next stage called the <u>Anaphase</u>. Here the cell also starts dividing.
Finally, the last phase, called the <u>Telophase</u>, marks the end of the cell division where the cells are eventually split into two in a process called cytokinesis.
Reproductive isolation is the very factor that causes the development of what we call "species" according to the biological species concept. The reason cats and dogs are different species is that they can't mate, so we call them "reproductively isolated."
Jellyfish are like corals, gorgonians and anemones they belong
in the group called cnidarians also jellyfish is a kind of invertebrates. This
animal group has stinging cells which they use both to capture their prey and
also as a form of defense.the type of movement that the jellyfish has is called passive locomotion another example aside from jellyfish which is sailing are <span>kiting (spiders) and rolling (some beetles and spiders).</span>
