The diploid number of the fern and onion plants are
fern: 1010
onion plant: 16
The formula of the diploid is 2N where N represents the haploid number.
Diploid = 2N ;
fern:
1010 = 2N
1010/2 = N
505 = N ;
onion plant:
16 = 2N
16/2 = N
8 = N
The haploid number for the fern is 505 and the haploid number for the onion plant is 8.
I am not really sure, but I guess it is the temperature.
By using educated guessing, you can exclude brightness and age and also mass as they can vary and still cannot determine the other characteristics from one of them.
And also by knowing that pressure is known using equations only by temperature, and pressure actually can be considered to be responsible to form or deform the star.
Hope this helps.
