3. energy processing ex. celluar respiration, photosynthesis
4. growth and development ex. crystals grow into minerals, fire
5. reproduction ex. sexual, fire reproduces
6. response to the environment ex. fox loses white fur
7. evolve: change in population over time, natural selection. individuals cant evolve in bio
Different levels of complexity
atoms-->molecules--> organelles(subcellular)--> cells (basic unit of life)-->tissues (similar cells for common purpose)--> organs (collection of tissue for common purpose)--> organism (individual)--> population (all members of one species)-->communities (diff species interacting together)--> biosphere
the whole is greater than the sum of its parts. allows for why atoms work together. ex. break down car
Convert light to energy (photosynthesis)/animals.
nutrients get recycled this way.
function! shape of things is important.
Ex. birds=large surface area due to wings, hollow bones.
neurons- high speed communication/ one long narrow strand to travel fastest.
mitochondria-inner membrane is folded to increase surface area
All life is made up of 1 or more cells.
What do all cells have?
molecule heretity (DNA)
ribosomes (protein synthesis)
what are the two types of cells?
prokaryotes (bacteria) and eukaryotes
"before the nucleus"
small 0.5-10 micrometers (millionth of meter)
nucleus+membrane bound organelles
maintenance of internal conditions within a tolerable range
ex. body temperature
Hot--->sweat---> cool ----> ok
Cold--->shiver (release heat)--->warm---> ok
a change in a variable triggers a response that counteracts the change
ex. low blood sugar=hungry
when you're hot, your metabolism goes up. sweat faster and cool down.
dangerous (causes opposite of homeostasis)
a change in a variable triggers response a mechanism to amplify change
important during: child birth (uterus contracts) and sexual response
the naming and classifying of organisms (least inclusive to most inclusive)
Name the 3 domains
Name the 6 kingdoms and what domains they are under
