Hox genes - control the expression of genes that influence animal morphology (sponges are simple animals that do not have Hox genes) acoelmates - triploblastic animals without a coelom, their bodies are solid and have no cavity. Ancestors of animals... - diverged from ancient fungi, between 675 million and 800 million years ago, believed to be a suspension feeder similar to Choanoflagellates Animals are.. - -multicellular (without cell walls) -heterotropic -develop from embryonic layers ...

ADH: always digging holes. this is an easy way to remember that antidieuretic hormone allows reabsorption of water from kidneys, therby concentrating the urine. caffeine and alcohol are ADH blockers Anterior Pituitary Hormones "FLAGTOP" F: Follicle Stimulating Hormone L: Luteinizing Hormone A: ACTH G: Growth Hormone T: Thyroid Stimulating Hormone O: MSH - melanOcyte stimulating hormone P: Prolactin FSH in males directly stimulates spermatogenesis - sperm look like "FiSH." In fem...

Phylogeny - Classification of organisms according to evolutionary relationships. Taxonomy - Evolutionary classification Linnaean system of classification (taxonomy) - Domain> Kingdom> Phylum> Class> Order> Family> Genus> Species (Did King Phillip Come Over For Grandma's Soup) [ex. Homo sapien](italicized) Phylogeny relationships - Basal Group: Branch from oldest common ancestor, no other branch from species. Sister Taxa: Share common ancestor Homologies - Comparing...

Hypothesis vs Theory - hypothesis is and educated guess while a theory is concept that is well supported by observation, experiments, and data. Hardy-Weinberg - No migration, choice of mates random, mutation does not occur, no selection pressure Adaptive radiation - a population colonizes a new habitat and go through natural selection, adapt and become new species (finches). allopatric - isolated population become new species. (porkfish landbridge) Alveolata - Ciliates and dinoflagellates...
