Crust is destroyed: A. near ocean ridges.
<u>Explanation</u>:
Crust can be explained as the outermost shell of terrestrial planet. The formation of earth is with three layers. These are mantle, core and crust. The formation of crust is with solid rocks as well as minerals. The beneath part of crust is mantle and it also made with hard rock and minerals. The layers of earth are constantly contact to each other. The formation of oceanic crust is at mid ocean ridges while it has been devastated at the subduction zones. According to some research, the crust has been at its higher levels of destruction.

Answer:
45 chromosomes (2n1 + n2)
Explanation:
The allotetraploid 2n1+2n2=60 has 60 chromosomes total, two sets of them of type 1 and two sets of chromosomes from the other type (2).
If the suspected type 1 parent is diploid with 30 chromosomes, then the allotetraploid has 30 type 1 chromosomes and 30 type 2 chromosomes.
<u>During meiosis, the germ cells reduce the total chromosome number by half.</u>
- The gametes produced by the allotetraploid will have 15 type 1 chromosomes and 15 type 2 chromosomes.
- The gametes produced by the suspected parent will have 15 type 1 chromosomes.
When these gametes combine during the backcross, the F1 zygote will have a diploid number of 30 type 1 chromosomes (15 coming from the allotetraploid and 15 coming from the suspected parent) and 15 type 2 chromosomes (which will be haploid because they all came from the allotetraploid).
