number because a normal karyotype has 22 autosomes and 1 pair of s€x chromosomes
(sorry if I'm wrong)
I'm pretty sure it's primary growth. I might not have studied this type of biology yet, but secondary growth would definitely not be the answer.<span />
The average distance is 16,000 km
Converging rate is 10 cm/year
1 km = 100,000 cm
= 16,000 × 100,000/10 cm/year
= 160,000,000 years
It will then take 160 Million years to collide.
Hey, how are you doing?
The answer to your question would be:

i believe.
Hope this helps, and if you need further help, contact me!
