Yesssssssssssssssssssssirrrrr
The cell’s DNA is replicated or copied before cell division because it is important for the cell to have 2 DNA molecules because the cell is going to divide into 2. Each new cell need a 1 DNA
The time it takes in milliseconds for the brain to transmit a signal to your skeletal muscles can be determined given the speed and distance. It was given that the signal travels at approximately 25 m/s while the distance between the brain and one' hand can be set to approximately 1 m. To obtain the time, we divide the distance by the speed and convert it to milliseconds.
The equation would be: (1 m/ 25 m/s)*(1000 ms/1 s) = 40 ms.
Thus, it will take 40 ms for the brain's signal to travel before it can command your skeletal muscles to react accordingly.
