Muscular contract and lengthen to control movement and support a given organ may be comprised of some or all of these tissue types (e. g. human stomach contains all four) 7. life cycle is mostly diploid animals" life cycles are much simpler fertilization two haploid cells join to make diploid. Meiosis diploid cell divides to haploid. None of these characteristics are unique to animals!
