I am pretty sure it is animal cells and plant cells considering I learned that last year in 6th grade
Meiosis takes place in the gonads of most organisms.

I think the answer should be medulla oblongata or foramen magnum.
The major nerves that leave brain should form a thick cord in the brain stem that called medulla oblongata. Medulla oblongata will pass a big hole in the base of the skull that called foramen magnum. Depends on what part the question asked(bone or tissue), it probably between those two options.
