Review Guide: General Questions/Skills: 1. Be able to draw a polypeptide given only the letter designations for the amino acids. 2. Given a list of 6 organisms (mentioned in class)‚ be able to draw the big tree‚ labeling three domains‚ the root‚ and relative branch lengths for the domain. Origin is on bacteria line in the middle. Archaea are generally shorter lines‚ bacteria are the intermediate lines and eukaryotes are the longest lines. Organisms: Are there going to be specific

Differentiate heterotrophs and autotrophs 1. Heterotrophs: need to obtain energy from an outside source 2. Autotrophs: create energy and food for themselves Some reactions are exothermic because their PEreactants is Higher than PEproducts 2. Understand that energy to sustain life is derived from chemical

new genera‚ and 87 new species were described (Hoppenrath‚ 2012). Many dinoflagellates are primary producers of food in the aquatic food webs (Faust‚ 2014). They use photosynthesis or the Sun for their energy. Although other dinoflagellates are heterotrophs and some are both! Most of them have protective cellulose plates that become encrusted with a hard‚ unreactive‚ colorless compound. Found in the plasma membrane are membrane bound sacs and commonly known as alveoli. The function of the alveoli

Unlike autotrophs‚ chamois cannot make their own food‚ which means they are heterotrophs. Their diet consists of leaves from shrubs and bushes and grass. Because chamois only eat plants‚ they have no prey. However‚ wolves‚ foxes‚ wildcats‚ and humans are their predators who kill and eat them. Reproduction

All living things must maintain homeostasis in order to stay alive. A) Homeostasis: A balanced state in an organism’s body. B) Failure to maintain homeostasis results in disease or death. C) Homeostasis is often maintained using feedback mechanisms. 1. Feedback mechanisms
