Question #a0e14 - Socratic G1 Phase S Phase G2 Phase M Phase (G0 Phase) In G1 Phase the cell is growing and getting ready for replication In S Phase the DNA is copied G2 Phase is when the cell waits gets ready for replication M Phase is Mitosis G0 Phase is when the cell growing or dividing Keep in mind there are three checkpoints along the way after G1, S, and G2 phases
What role does mitosis play in the development of cancer? No cancer without mitosis Mitosis is the way of cell division and as we all know, cancer cells like to divide They break every possible chains that could stop them from doing this (like apoptosis) Overall, mitosis helps cancer survive and spread
Is the luteal phase measured by the number of days with . . . - Socratic The luteal phase starts right after ovulation Menstrual cycle could be divided in preovulatory and postovulatory phases as long as the ovary is concerned Luteal phase starts midcycle, i e after ovulation and ends with the end of the lunar cycle Luteal phase starts after egg is released from the ovarian follicle by ovulation The empty follicle soon gets transformed into an endocrine gland
d_z2 orbital participate in sp^3d hybridization and not any other d . . . Because the resultant trigonal bipyramidal geometry of the hybrid orbitals requires both lobes to be the same phase on the z axis, and requires five total orbitals To form the trigonal bipyramidal electron geometry with five hybrid orbitals, we need to put in five orbitals: 1 xx ns + 1 xx np_x + 1 xx np_y + 1 xx np_z + 1 xx (n-1)d_(z^2) -> 5 xx sp^3d Every hybrid orbital needs an s orbital
What are two reasons why cells divide? - Socratic There are mainly 2 types of cell divisions that actually exist-meiosis and mitosis The reasons why cells divide can be for numerous purposes- As seen from the perspective of mitotic division, in which the no of chromosomes is conserved,i e ,46 chromosomes in human somatic cells Cells can divide through mitosis to replace the worn out or dead cells in the body of living organism Another
How does matter change from one state to another? | Socratic Atoms molecules gain enough energy to increase the mean atomic molecular separation by overcoming inter-atomic molecular forces Solid Liguid Particles are initially held in an equilibrium position by inter-atomic molecular bonds, and they vibrate about that equilibrium As energy is transferred to the substance the atoms molecules gain enough energy to overcome some inter-atomic molecular
Does a tetrad occur even if there is no crossing over event that is . . . Answer is no Tetrad forms during meiosis first division of prophase Crossing over takes place in two homologous chromosomes There is exchange of genetic material during crossing over These chromosomes look in set of four therefore called tetrad During mitosis simple cell division there is no exchange of genetic material
Question #9b08b + Example - Socratic There are four phases of matter: Solids Liquids Gases Plasmas 1 Solids Individual atoms molecules in the substance are strongly bound close together Atoms molecules vibrate around an equilibrium position Solids to not adjust their shape to fill their container 2 Liquids Individual atoms molecules are weakly bound together, the mean separation may be slightly larger than that of
What phase of #CO_2# exists at #-57^@ C# and #2 atm#? - Socratic This is just asking you to use your finger to trace where you are on the phase diagram Think back to when you learned about graphs Treat T, the temperature, as your x value, and P, the pressure, as your y value Now point to where T = -57^@ "C", and P = "2 atm" Did you point here? So then, what single phase is here? For further practice with phase diagrams, see here
