Bio Unit 14

• Bacteria=Eubacteria. Autotroph or heterotroph. Ex: E. coli Or strep
• Archaea=archaeabacteria. Autotroph or heterotroph. Ex: methanogens or halophiles
• Domain Eukarya= protista, fungi, animalia, and plantae
• Protists= eukaryote, mostly unicellular, some multi. Cell walls of cellulose, autotrophic or heterotroph. Ex: paramecium, amoeba, giant kelp, and slime mold
• Fungi= eukaryote, mostly multicellular, some uni. Cell wall of chitin. Heterotroph. Ex: mushrooms, yeast
• Plantae= cell wall of cellulose, autotroph
• Animalia=no cell wall, heterotroph
• Animal like protists are classified by how they move
• Flagellates- move using flagella
• Ciliates- move using cilia. Example is paramecium
• Plant like protists are characterized by color
• Fungi are classified by how they reproduce
• rainforest-very high rainfall, very hot
• savanna- grasses, zebras, lions
• temperate decidious forest- broad leaf trees that lose their leaves in the fall
• taiga- needle-like, evergreen trees, very cold
• desert- very little rain fall, hot during day, cool at night
• ocean- largest aquatic biome
• estuary- mix of salt and fresh water
• mutualism- both organisms help each other
• commensalism- 1 is benefited, one is unaffected
• parasitism- 1 is benefited and 1 is harmed
• symbiosis- relationship between organisms
• predator- organism that is doing the hunting
• prey- the hunted
• density dependent limiting factors-limit the population because of a population's size
• density independent limiting factors- limit all populations the same regardless of size
• Density dependent examples- competition, disease, predators, overcrowding
• Density independent examples- weather, parasitism
• Photosynthesis removes carbon from the atmosphere. Respiration puts it back
• Phosphorus isn't present in the atmosphere
• Denitrogenfixation puts nitrogen back into the soil. Fixation releases it
• DNA monomer is a nucleotide
• DNA Polymerase and Helicase are involved in the replication of DNA.
• DNA: 2 strands. A,C,T,G. Deoxyribose
• RNA: 1 strand. A,U,C,G. Ribose
• Missense Mutations - a mutation that changes an amino acid
• Nonsense Mutations - mutation that changes an amino acid into a stop codon
• Mutations - a change in DNA
• Gene mutations - small change in a sequence of dna
