Pass.
Feedback mechanisms
Answer> Negative feedback=Stimulus invoking a response and the response
inhibiting stimulus. Positive feedback=the stimulus invoking a response and the
response providing a stimulus. IE. platelets increase, cells dividing.
Kingdoms
Answer> Bacteria, Archaea bacteria, (both have organisms that are
unicellularcomprised of prokaryotic cells-no nucleus).
Archaea bacteria - exist extreme (high pH, low pH-Dead Sea).
Protista (Eukaryotic cells-membrane bound nucleus), -looking to divide this by
plant unicellular to multi-cellular.
Fungi, (multi-cellular organisms inovlved in decomposing. distinguising in
photosynthesis).
, Plantae,
Animalia. - Rather than sun photosynthesis but by foods.
Emergent Properties
Answer> Characteristics that we see from a higher level to a lower level in bio
organization.
Biological organization- increasing levels comes greater complexity.
Answer> Chemical - lowest level-atoms, molecules, proteins. organelles, cells.
Organelles
Tissue level- collection of similar cells associated with specific function.
Organ level-differentiation cells (different) associate with different organs.-
digestive system-cells break down gastric juices, also generate mucus.
Organisms- Individual living things.
Populations- individuals as one specifics within a general geographic locale.
Communities- all populations within a given geographic locale.
