CHAPTER 1: Evolutions, themes of biology, and scientific inquiry - Coggle…

- - - - Ecosystems: Consists of all living things in a particular area, and all nonliving components that life interacts with
        
        Molecule: Chemical structure consisting of two or more units called atoms
        
        Tissue: Group of cells that work together performing a specialized function
        
        Organ: Body part made up of multiple tissues and has a speccific function
        
        Organism: individual living things
        
        Population: consists of all individuals of a species living within the bounds of a specific area
        
        Community: Array of organisms inhabiting a particular ecosytem
        
        Cell: Life's fundamental unit of structure, the most basic unit of life
        
        Organelle: Various functional components present in the cell
    - - CELL THEORY:
        
        smallest unit of organization 2. All living things are made of cells 3. All cells come from pre-existing cells
      - Prokaryotic
        
        Found in 2 domains of single-cell microorganisms
        
        Archaea- extremophiles
        
        (EU) Bacteria- everyday bacteria
        
        Lacks a nucleus or other membrane -enclosed organelles
      - Eukaryotic
        
        Found in Domain Eukaryia
        
        Contains all other forms of life ( plants/ animals)
        
        Contains nucleus
  - - - Positive Feedback: - Not as common - Reinforcement of a process in order to maintain homeostasis -EX: Contractions during labor
      - Negative Feedback: - More common - Stopping a process to maintain homeostasis- Ex: Body temperature regulation
  - - - Natural Selection/ "Survival of the fittest"
    - - Bacteria
      - Archaea
      - Eukarya
        
        4 subgroups: Kingdom Plantae, Kingdom Fungi, Kingdom Animalia, Kingdom Protists
  - - - 2 strands form double helix
      - The sequence provides a blueprint for protein building
      - Deoxyribose Sugar
      - Building blocks aka Nucleotides : Encode genetic information in various combinations
        
        BASES: Guanine, Cytosine, Thymine, Adenine
        
        A-T , C-G
    - - 1 strand
      - Ribose Sugar
      - BASES: Guanine, Cytosine, Adenine, Uracil
        
        C-G , A-U
