Crossing over is a process that happens between homologous chromosomes in order to increase genetic diversity. During crossing over, part of one chromosome is exchanged with another. The result is a hybrid chromosome with a unique pattern of genetic material.

Explanation:
In the early days of development, in an embryo, the cells are pluripotent and can differentiate into any kind of cell of the organism. As the embryo develops, autocrine and paracrine signaling between the cells of the embryo causes the cells to migrate to particular regions of the embryo and begin differentiating into respective parts of the organism. This signaling causes differential silencing of particular genes of the cells depending on the type of cells they will differentiate into. As the embryo develops into a fully grown organism, these cells lose potency (except for stem cells) and become fully differentiated into respective limbs or organs of the organism.

<span>Hemostasis is the process of the body that seals blood vessels that rupture. The process is basically starts with an injury, then vascular spasm, platelet plug formation and then coagulation.
During blood clot formation, blood is transformed into solid gel at site of damage, where plasma fibrinogen is converted into loose fibrin molecules, which bind together to form mesh. Platelets and blood cells get trapped here by the fibrin strands, which produces a clot. This part of the clot formation is called coagulation.
