Answer:

I) Sexual reproduction

II) Mutation

Explanation:

Variations refer to the difference observed within organisms of the same species. Variation are introduced into a population by:

- new genetic combinations that occur during sexual reproduction (i.e during meiosis)

- mutations, spontaneous changes that occur in genes and chromosomes.

Similarities between mitosis and meiosis (as many as possible, I really need help)
vesna_86 [32]
Meiosis and mitosis are both preceded by one round of DNA replication; however, meiosis includes two nuclear divisions. The four daughter cells resulting from meiosis are haploid and genetically distinct. The daughter cells resulting from mitosis are diploid and identical to the parent cell. 
so the similarities are: 
-ways for cells to divide 
-same number of chromosome as the original cell 
-both have the basic 5 phases 
-both processes go through chromosome replication 
-Meiosis II is similar to Mitosis 
I hope this is helpful :)))

I believe you mean mid-ocean ridge?

If so, true.

A mid-ocean ridge or mid-oceanic ridge is an underwater mountain range, formed by plate tectonics.

This uplifting of the ocean floor occurs when convection currents rise in the mantle beneath the oceanic crust and create magma where two tectonic plates meet at a divergent boundary.

A mid-ocean ridge demarcates the boundary between two tectonic plates, and consequently is termed a divergent plate boundary.
