Intro to Biology  Biology – study of life o Many branches of science greatly utilize biology like ecology, chemistry, etc  Science is process for questioning & testing answers o Hypothesis: an idea/possible answer for a question that must be tested/supported  If the testing does not support the hypothesis than the hypothesis is  dropped and a new one is posed o Theories: idea (hypothesis) that has been tested & well proven (still can be  refutable though)  Exploring ideas, testing, & evaluating results is the scientific method  12 standards basics that apply to all fields of Biology o 1 ~ Cells are the most basic unit of life  The term organisms can be applied to all living things  The makeup of an organism differs from its environment  Cell theory  Theory explains that one or more cells compose an organism  Cells are smallest living thing  Cells go through a process called cell division to create new cells o 2 ~ Energy is required to sustain life  Energy is supplied by environment (plants use sunlight, human eats an  apple)  Chemical reaction is needed to utilize energy in an environment  (photosynthesis)  Metabolism is the process where energy is broken down & used for cell  creation o 3 ~ Organisms coexist w/ their environment   Organisms must adapt to their changing environment  Hibernation, reptiles switching btw sunlight & shade o 4 ~ Homeostasis  Process in which organisms create stable internal environment to  effectively continue life processes o 5 ~ Growth/development is a part of organism adaptation   Growth involves number/size increase  Development involves change of characteristics/abilities  Growth of babies start as single cell & grow to become  multicellular o 6 ~ Genetic code essential to reproduction  DNA/RNA govern makeup & ability of a living thing  DNA (deoxyribonucleic acid)  RNA (ribonucleic acid)  DNA  → Genes  → RNA  → Polypeptide → Protein o 7 ~ Organisms always differ from one generation to the next  Evolution involves inheritable characteristics over generations o 8 ~ Every species shares evolutionary ancestry o 9 ~ Structure directly effects function & vice versa  Giraffes’ long necks are directly attributed to their function of reaching  leaves in tall trees o 10 ~ Differing interactions among (or in) organisms can establish new functions  Multiple functions/structures can work with each other or environment to  create a new property of life   Differ components of the eye have individual functions, but  together it gives humans and animals vision with color, textures,  etc  This is called emergent property  o 11 ~ The discoveries in Biology (and other sciences) are not set in stone; a very  exploratory science  Biologist are always questioning life & its processes & trying to find  explanations o 12 ~ Biology is incredibly influential  Biology helps us create medicine, understand environmental processes,  and build technologies to improve life  10 (ish) Levels of Biological Complexity (simple to complex) o atoms→molecules/macromolecules→cells→tissues→organs→organisms/species→ population→community→ecosystem→biosphere  Atoms: smallest building block of anything & all matter is composed of  atoms  Molecules/Macromolecules: atoms fuse to make molecules; clusters of  molecules become macromolecules  Cells: structured molecules/macromolecules; this stage & on is considered life  Tissues: there are differing cells, but cells of the same caliber can form  together and create tissue   Organs: multiple, different tissues can form together to create organs  Organisms: broadly, every living thing can be considered this  Organisms that share the same characteristics/mannerisms in the  same environment are considered a species  Population: collection of species that share the same environment are  considered a population  Community: different species coexisting in an environment is called a  community  Ecosystem: interaction btw environment & its multiple communities can  be studied  Ecologist study these ecosystems  Biosphere: every living thing and its space that makes up the Earth is  called the biosphere Unity/Diversity of Life  Life established 3.5 to 4 billion years ago  Evolutionary changes can happen 2 ways o Vertical Descent w/ Mutation (VDM) o Horizontal Gene Transfer (HGT)  VDM o Evolution of species involves random genetic mutations generation to generation   Mutations are random shifts in gene code  Some of those mutations can give species higher chance of survival  Genetic mutations that stick from generation to generation that increases  the species’ lifespan is called natural selection (survival of the fittest)  HGT o Phenomenon where genetic material is transferred instead of inherited  Can be done by unicellular/multicellular organisms   This process is typically done by bacteria & viruses   This is what produces antibiotic resistant microbes  Taxonomy – the grouping of species  o Categories within taxonomy goes from very broad to very specific (domain to  species) Domain (Bacteria, Archaea, Euk rya) ↓ Supergroup ↓ Kingdom (Protista, Plantae, Fungi, Animalia) ↓ Phylum ↓ Class ↓ Order ↓ Family ↓ Genus (Genera) ↓ Species  Bacteria: unicellular, common  Archaea: unicellular, extreme environments  Prokaryotic: simple  Eukaryotic: different in composition; nucleus in genes  Binomial Nomenclature: specific scientific names for organism that help describe it o 2­part name where 1  part is the genus & 2  part is the descriptor o Genus capitalized, epithet is not Biological Fields  Different types of biological studies o Ecology  Study of organisms in their environment o Anatomy/Physiology  Examination of structures/function of organisms (animals & plants) o Cell Biology  Study of cells o Molecular Biology  Study of molecules, proteins, etc o Systems Biology  Study of emergent properties & their occurrence
