a way to gain knowledge by a dynamic process of gathering and testing information.
What is a hypothesis and what isn't it?
Proposed explanation of a set of observations that is testable and falsifiable.
It is not a theory or a guess.
What is a theory?
Hypotheses or set of hypotheses for which many types and repetitions of experiments provide evidence.
What is the definition of Biology and name the groups associated with that?
Biology is the "study of life"
Processes and Activites
(What makes something alive?) what are they composed of and their definitions?
All living things are composed of cells
Unicellular or multicellular
Prokayote - A cell that lacks a nucleus and other membrane-enclosed organelles; includes the bacteria and archaea. Simpler in form.
Eukaryoke - An organism whose cells have nuclei and other membrane-enclosed organelles. Includes protists, fungi,plants and animals.
(What makes something alive?) What is the difference between biological growth and development?
Growth - change is size and / or number of individual cells (duration can vary)
Development - all changes that occur in an organisms (lifetime)
(What makes something alive?) How do organisms regulate metabolic processes?
Metabolism - all of the chemical activities in an organism / also the key in maintaining homeostasis (balance)
(What makes something alive?) Organisms respond to stimuli...what are some examples of stimuli and how do movement and locomotion differ?
Stimuli - physical or chemical changes in their internal or external environment. Ex. (changes in color, intensity, or direction of light; in temperature, pressure, or sound; flowers to bees)
Movement is moving without changing location.
Locomotion is moving from one place to another.
(What makes something alive?) Organism reproduce...how do they reproduce and give definitions for each?
Organisms reproduce Asexually and Sexually.
Asexual - reproduce by themselves / they are genetically the same (ex. amoeba that has grown to a certain size and splits in two)
Sexual - is carried out by the fusion of an egg and a sperm cell to form a fertilized egg.
(What makes something alive?) Populations evolve and become adapted to the environments...what is a population and adaptation?
Population - Multiple of same species at the same place and time. (Individual organisms do not evolve - populations do)
Adaptation - Inherited characteristics that enhance survival in a particular environment.
(How do Biologists organize things)...list two ways and define them?
Reductionism - learning about a structure by studying its parts. (ex. cake and its ingredients) However, the parts don't tell the whole story.
Emergent properties - characteristics not found at lower levels. (You begin to see these properties at the Cell Level)
(How do Biologists organize things)...What is Taxonomy and binomial nomenclature?
It is the science of classification, naming organisms and putting them into a hierarchy.
Carolus Linneaus (Father of Taxonomy)
Binomial Nomenclature - This is the scientific naming of species. Always given 2 names - first part of the name is the genus (always capitalized), the second the specific epithet (not capitalized but whole name underlined or italicized).
(How do Biologists organize things)...What is systematics and name the orders and kingdoms?
The study of how organisms are related to each other through time.
KINGDOM, PHYLUM, CLASS, ORDER, FAMILY, GENUS, SPECIES (King Philip Came Over For Good Soup)
There are 3 domains and 6 kingdoms - Bacteria, Archaea, (Eukarya) = Protista, Plantae, Animalia, Fungi
