What are the four stagesof the cell cycle?
There is Gap1 (G1 stage) where the cell is when it's not dividing. Then Synthesis (S stage) where the cell's DNA is duplicated. After that you have Gap 2 (G2 stage) where the cell gets ready to divide. Then the cell divides in mitosis. It ends with cytokinese where the cytoplasm splits and the plasma membrane disconnects.
Cells nucleus during interphase?
DNA is always present in every stage of the cell cycle...reproducing it is the whole purpose of the cell cycle! In interphase, there are three phases: the cell grows (G1), duplicates each strand of DNA (S), and gets ready for mitosis (M). During the first part of interphase the chromosomes are long and thin, and single-stranded, making them very hard to see without a very powerful microscope. During the last 2 stages of interphase, the DNA is duplicated but is still long and thin. It is only in the prophase stage of mitosis that they are condensed enough to often be seen with a "normal" microscope on high power (400x) . By the end of mitosis, the doubled-chromosomes have been pulled apart and into opposite ends of the parent cell. When the cell has finished dividing, each "daughter cell" has the original number of single-stranded chromosomes. The chromosomes "uncoil", and the cell matures during G1 phase of interphase. Many people believe that DNA and/or Chromosomes (Chromosomes are made of DNA, remember.) are only present during mitosis. They just get fatter during mitosis by coiling tighter. Thus they are more easily seen. BUT.. just because you don't see them in interphase doesn't mean they aren't there!
What happens to the size of the molecules during a phase change?
the hotter it gets, the bigger the size will be
In which step would a mutation lead directly to the formation of an altered gene -?
DNA is copied and each new cell gets a full copy.
What happens at the waning crescent moon phase?
the moons lightness gets weaker ( darker in the light).
Which phase of cell cycle is the busiest?
The busiest phase of the cell cycle is the interphase. That's just the time before the dividing cell enters mitotis. It's basically just preparing itself for cellular division... It gets bigger and makes a copy of it's DNA.

What happens when a phase gets short and also when it get opened in a delta and star connection?
In star connection when two phase is short,it work as single phase system. In delta when one phase is open ,it work as a single phase.
Why is it importaint for chromosomes to be copied before cell division?
it ensure that the cell can survive before it gets divided
What is stance phase?
first position a pitch gets in before pitching
When copying files from one external harddrive to another are they copied to the computer during the process NOT counting the RAM but rather the computers harddrive?
No. They are not copied to the computer's harddrive. Just the destination drive gets the files.
Can you run a three phase motor with single phase generator with help of phase converter?
Terminology gets misapplied but a 3-phase converter produces a 3 phase supply from a single phase supply. The only proviso is that generator, converter and motor are all suitably rated and compatible.
What happens to the size of the molecules during a phase change?
the hotter it gets, the bigger the size will be
What is it called when the sunlit fraction of the moon that we can see from earth gets larger?
It is the waxing phase.
In which step would a mutation lead directly to the formation of an altered gene -?
DNA is copied and each new cell gets a full copy.
When a cell grows what phase copies its DNA and gets ready to divide?
Its called cell division
