In physics, chemistry, and other related fields like biology, a phase transition (or phase change) is the physical process of transition between one state of a medium and another. Commonly the term is used to refer to changes among the basic states of matter : solid , liquid , and gas , and in rare cases, plasma .
Phase transition, a transformation of the state of matter; for example, the change between a solid and a liquid, between liquid and gas or between gas and plasma; Quantum phase transition, a phase transformation between different quantum phases; Quantum Hall transitions, a quantum phase transition that occurred because of the quantum Hall effect
Mitotic exit is an important transition point that signifies the end of mitosis and the onset of new G1 phase for a cell, and the cell needs to rely on specific control mechanisms to ensure that once it exits mitosis, it never returns to mitosis until it has gone through G1, S, and G2 phases and passed all the necessary checkpoints.
Labor is separated into 4 stages. The first stage involves latent phase and active phase separated by the dilation of the cervix for 6 to 10 cm. The second stage is the pushing stage. The third stage involves the delivery of the placenta. And the last stage is the contraction of the uterus. [21]
In biology, a biological life cycle (or just life cycle when the biological context is clear) is a series of stages of the life of an organism, that begins as a zygote, often in an egg, and concludes as an adult that reproduces, producing an offspring in the form of a new zygote which then itself goes through the same series of stages, the ...
The G2 to M transition is dramatic; there is an all-or-nothing effect, and the transition is irreversible. This is advantageous to the cell because entering mitosis is a critical step in the life cycle of a cell.
Labor induction is the procedure where a medical professional starts the process of labor instead of letting it start on its own. Labor may be induced (started) if the health of the mother or the baby is at risk. Induction of labor can be accomplished with medication or mechanical methods. [99]
Before the zygote undergoes the midblastula transition it is in a state of fast and constant replication of cells. Cell Cycle with G1 and G2 phases. Orange circle shows what the cell cycle looks like before the MBT. The multi-colored inside circle shows what the cell cycle looks like after MBT and the addition of G1 and G2 phases.
