I got 0.4 something per hour for the menstrual cycle question

X and Y and 9 chromosomes for the male

1/75 seconds for the time it took for the nerve to send a signal down a 1.6m nerve. (I put my answer as a number not a fraction in milliseconds)

Got 0.45 per hour for the menstrual cycle, you had to round it to 2 significant figures.

I was gonna but 0.45 but i put 4.5
the answer was 0.075ms coz u have to do 120/1.6 using the speed distance and time equation you get 75 but then u need to divide it by a thousand to get 0.075 milliseconds

I’m happy menstrual cycle came up. I was annoyed though as I spent way to long on the first bit of the paper, to try and get down as much detail as possible, which meant that I had to rush the last page :frown:

I did 120/1.6 = 75
Then 1 second divided by 75 = 0.0133333333
Then 0.013333333 * 1000 to get it into milliseconds
= 13.3333

Idk I’m not sure I got it right
you don't do1/75 I have just found out u have to do 75x100
