36,37,38....gnathostome, mutualism, angiosperm

This is my dog! he blends in with my couch nicely. he is a good example of a gnathostome(big idea 1#23). These are animals that have jaws as well as several other unique features. Almost all vertebrates are gnathostomes. This most likely evolved from aquatic animals that had a connection between their throats and the gills, allowing them to get water throught the gills by opening and closing their mouths. This strengthened the jaw muscles and eventually organisms got to the point that they could capture prey in the jaws.
Apart from displaying my favorite of all jareds, this picture demonstrates a lichen, which is an awesome case of mutualism(big isea 4#12). This is a symbiotic relationship between two organisms in which both benifit. It is like a clown fish and a sea anemone, in which both species gain from the relationship by providing protection from predators and the fish eating harmful paracites. Lichens are pairs consisting of fungus and photosynthetic organisms, which provide water/nutrients and energy respectively.
this beautiful area full of flowers and clovers and other fancy things is an example of angiosperms(big idea 1#6), which are seed-producing flowering plants. Unlike gymnosperms, their seeds are surrounded by plant material, not exposed like on pinecones. They are commonly seen by us in he form of fruits which contain seeds. They are all flowering plants and can either self-pollinate or pollinate with other plants by taking advantage of pollinators, such as bees and bats.
