Meiotic Mysteries By: Karen Schindler In class we went over the cycle of meiosis‚ the sexual life cycle‚ and its stages. Meiosis has four stages which are‚ prophase I‚ metaphase I‚ anaphase I‚ and telophase I. In an adult before ovulation the oocyte goes back to meiosis forming a meiotic spindle of microtubules to segregate homologous chromosomes. When it reaches fertilization‚ the egg itself undergoes a second round of division segregating sister chromatids. Which is Prophase II‚ Metaphase II

BIOFERTILIZER: The pathophysiology of the Tuberculin reaction is explained thus: M. Tuberculi are engulfed by macrophages after being identified as foreign‚ but due to a self- preserving mechanism peculiar to TB it is able to block the fusion of the phagosome within which it is existing with the lysosome which would destroy it. So it can continue existing and replicating within the immune cell designed to destroy it. After several weeks‚ the immune system somehow [ mechanism as yet unexplained]

Fertilizers are essential in plant growth due to the lack of some nutrients in the soil. They contain three distinct categories which are the primary nutrients‚ secondary nutrients and metals. (hazri). In order for a plant to develop growth‚ the basic needs of carbon (C)‚ hydrogen (H)‚ and oxygen (O) are required which are available in the air and water. Also‚ a boost of macronutrients are also essential for plant growth which are obtainable from chemical fertilizers mainly nitrogen (N)‚ phosphate
