Sexual reproduction is the reproductive process that 1) keeps species from changing. 2) produces identical offspring. 3) causes mutations. 4) creates genetic variety.

2: I think you should go with two because it makes the most sense out of all of those answers. But if not 2, I would go with 4.

label a cell membrane

label b cytoplasm

label c ribosomes

label d dna

the membrane forms the outside of the cell

cytoplasm is the liquid within

ribosomes are the components within that distribute rna

the dna is the genetic make-up

your answer is going to be physical weathering
