The cell increases in mass. The chromatids of each chromosome (two sister chromatids of one chromosome) are held together by a centriole.
Chromosomes coil up together forming a spindle. Homologous chromosomes come closer and form a tetrad. For each pair of homologous chromosomes the exchange of genetic material may result in the crossing over of chromosomes. New combinations of alleles on chromosomes are the result of crossing over.
The homologous chromosomes disperse and move towards opposite poles of the cell. The resultant is the assurance that each new cell that will eventually form would receive only one chromosome from homologous pair.
The spindle breaks down and the chromosomes uncoil eventually dividing the cytoplasm into two separate portions. Two daughter cells form. They contain exactly half of genetic information of parent cell. This is because they contain only one homologous

Case Study Analysis based on James Fowler’s Stages of Faith Faith has been mostly intertwined with religious ideas and belief systems for many people, making it sound synonymous even. However, faith has been defined differently by James Fowler when he created the Stages of Faith, wherein instead of faith being solely the product of a religion or a belief, it is simply defined as the major reason why people behave the way they do, be it due to aspirations, traditions, speculations, religion, or a mixture of all of these (“Faith Development” 416).
Meiosis also known as reduction division is a type of cell division where the cells divide to produce cells containing half the number of chromosomes. This type of cell division constitutes a very important part of sexual reproduction and all eukaryotes reproducing sexually have meiosis as a part of cell division. However, the prokaryotes i.e. the bacteria do not reproduce by meiosis.
Meiosis is another type of cell division which occurs in reproductive cells or germ cells only. It involves two fissions of the nucleus and gives rise to four sex cells or gametes. Each of the cells has half the number of chromosomes of the parent cell. Meiosis occurs in 2 stages, meiosis -1 and meiosis-2.
Research has shown that some of these genes that are only expressed in the testes are also expressed in other somatic cells when they become cancerous tumor cells. The cells in the testes often escape the cells of immune system, because of which they are protected from antibodies that are directed towards cancer-testis antigens.

Proscenium stages visually allow a much more thrilling approach for creation of stage images. Their depths allow for perspectival effects, something impossible in other stage settings. The distance they allow between audience and actors deem them the
The baby can sit on his/her own and grasps objects through a raking grasp. Can hold toys from one hand to the other. Gets sensitive to the mother’s voice

During the pre-modern period, globalization was in its earliest stages, and affected many cultures globally. As a result, this paper seeks to describe globalization in its earliest stages. It seeks to do so by discussing
These include prophase, metaphase, anaphase and telophase. However, an interphase stage is included. Interphase is not one of the stages of mitosis. It’s just a period when the cells are preparing for the next division. Mitosis occurs
