Answer: The great molecular biologist and Nobel laureate Francois Jacob has stated that the human brain has a built-in need for order. From earliest times, human beings looked out and recognized cycles, repetitive patterns in nature—day following night, the seasons, tides, lunar cycles, plant succession, animal migration—that conferred the ability to predict their recurrence, and thus people acquired a semblance of understanding of and control over the cosmic forces impinging on their lives.

Coccus-shaped bacteria can be found in pairs, chains, squares of four, cubes of eight, or grape like clusters. More specificially, this type of bacteria found in pairs is called diplococcia, in chains is called streptococci, in squares of four is called tetrads, in cubes of eight is called sarcinae, and in grape like clusters called staphylocci.
In meiosis, cell division will occur two times. It shall be called Meiosis I and Meiosis II. And Meiosis happens to our sex cells, egg for female and sperm cells for the male. There four stages in Meiosis I, Prophase I will happen when who homologous chromosomes exchange DNA. Metaphase I will happen when the pair move together in the center. Anaphase I is when the who homologous chromosomes are pulled apart to opposite poles. Telophase I is when the the first division of the chromosomes happen. Producing two 24 chromosomes cells. The nest division will produce haploid or 12 chromosome cells. In Propase II, the nuclear walls will disappear once again, in the Metaphase II the cells will meet again in the center. In Anaphase II the chromatids will be pulled apart. And then lastly in the Telophase II, the chromatids will not be 2 haploids. So in Meiosis, 4 sex cells are produced.
Answer:
In the traditional phylogeny platyhelminthes is depicted as a lophotrochozoan phylum. What probably led to this change?
The removal of the acoel flatworms (Acoela) from the Platyhelminthes allowed the remaining flatworms to be clearly tied to the Lophotrochozoa.
