56,57,58... eukaryote,saturated far,heterotroph

This is a rib bone from a whale, which is a heterotroph(big idea 2#19). Heterotrophs are any organisms that cannot fix carbon compounds from CO2 as an autotoph can. Instead, thy must consume other organisms and digest their carbon compounds. Whales can be either secondary or tertiary consumers in an ecosystem depending on the type.  Whales are the largest heterotrophs in te modern day, but the largest ever to live was amphicoelias fragilimus(those long-necked things).
this seal is an example of an organism that contains saturated fat(big idea 2#32). This is a moleculat that has 2-3 hydrogens bonded to every carbon depending on the position in the chain, meanin that all atoms are fully bonded and the chain is straight, unlike an unsaturated hydrocarbon that has a double bond betwen carbons and a bend in the chain. Saturated fats are known as "animal fats" becuase animals store enegy this way long-term.(short term energy is stored as glycogen in the liver and muscle)
 The friendly bird shown above is an example of a eukaryote(big idea 3#3), which is an organism with eukaryotic cells that contain orgenelles bound within membranes, such as mitichondria, chloroplasts, and nucleus. The other type of cell is a prokaryote, which has no membrane bound DNA and has no mitochondria/chloroplast. They are more simple and tend to be unicellular organisms with a thick outer layer. All cmplex life is eukaryoric.

  1. Where was this whale bone picture? Great job, Ryan, most of these have been spot on, but there are a couple that are a bit of a stretch. Using plants for things like ATP and enzymes... there are better things you can use that could be more visible. An organism doing physical activity could be used for ATP, or even a something that captures the idea of an ATP synthase if you can find one. For enzymes think of the first place you digest your food! If it can be more visible than showing an organism that has the trait, try it!

    Thanks for being on top of your work, RYan, even at 1 AM. Almost done!
