Question

why do heart cells have different characteristics than skin cells? (1 point)
heart cells express different genes than skin cells.
heart cells have different dna than skin cells.
heart cells reproduce by cell differentiation.
heart cells reproduce by mitosis.

Explanation:

All somatic cells (like heart and skin cells) in an organism have identical DNA. Cell differentiation occurs when cells express distinct subsets of their shared genes, leading to different structures and functions. The other options are incorrect: heart and skin cells share the same DNA; cell differentiation is not a reproductive process, and both cell types (when dividing) use mitosis, which does not cause their functional differences.

Answer:

Heart cells express different genes than skin cells.
