| three methods of asexual reproduction | binary fission, budding, fragmentation |
| union of egg and sperm | zygote |
| type of cells that make up the archenteron | endoderm |
| oragnisms best suited to a particular environment survive and reproduce at a higher rate, according to this theory | natural selection |
| The condition in which organisms have male and female reproductive systems | hermaphroditism |
| Skeletal muscle develops from this embryonic germ layer | mesoderm |
| The nervous system is derived from this embryonic germ layer | ectoderm |
| Organisms that develop in a placenta and experience live birth | viviparous |
| An organism that is diploblastic has an endoderm an ectoderm, but lacks this embryonic cell layer | mesoderm |
| primitive gut that forms the digestive system. | archenteron |
| Most mammals (like humans) obtain their nutrition during embryological and fetal development through this | placenta |
| type of gut that gives rise to a mouth and anus. | complete |
| one of these can be removed from an embryo during the cleavage stage of development, but it will continue to develop into an entire organism | blastomere |
| segment of DNA that codes for the production of a specific protein | gene |
| During transcription, the information in DNA is converted into this | mRNA |
| During translation, the information in mRNA is converted into this | amino acid sequence |
| Sexually reproducing organisms produce gametes | haploid |
| Variation is created in sexually reproducing populations by this process | meiosis |
| A major benefit of sexual reproduction | produces genetic variation |
| Organisms that are born live in eggs | ovoviviparous |
| 21. The movement of water across a membrane from an area of high water concentration to an area of lower water concentration | osmosis |
| classify organisms from the least specific, most diverse (kingdom) down to the most specific, least diverse. | kindgom, phylum, class, order, family, genus, species |
| phylum that includes sponges | Porifera |
| phylum that includes fish | Chordata |
| phylum that includes flatworms | Platyhelminthes |
| Phylum that includes earthworms | Annelida |
| phylum that includes jellyfish | Cnidaria |
| Phylum that includes crayfish | Arthropoda |
| phylum that includes clams | Mollusca |
| Phylum that includes starfish | Echinodermata |
| Phylum that includes roundworms | Nematoda |
