bio exam 1

how organisms interact with each other and their environment

how species evolve overtime through natural selection

life is characterized by highly ordered structures(cells, sunflower seed, face structure)

organisms reproduce their own kind -hybrids are special case, can’t reproduce

DNA is inherited and control growth

all organisms respond to stimuli ex: bunny runs from predator

organisms need to regulate/maintain internal environment -thermoREGULATION = humans that go through homeostasis - thermoCONFORM = reptile who rely on their envir. heat

organisms take up energy and use it

traits best suited to their environment ex: camel w thick fur and hump that store food

domain of life SINGLE CELL PROKAROTYE (no membrane bound organelles)

domain of life kingdoms: animals, fungi, protists, plants membrane bound organelles

broad sentence, propose testable explanation

IF, THEN statement

last universal common ancestor from bacteria

explanation based on extensive evidence when scientist all come together with the same hypothesis

they wanted to determine if the fur color of the mouse helped it survive longer or not

life depends on the flow of info (dna -> rna -> protein)

every structure is created to have a certain function

ENERGY IS LINEAR, matter is circular sun-> producuer->chemical energy-> consumers

predator-prey mutualism herbivores and plants

-decent with modifications: species living today are from ancestors different from them -natural selection -evolution is NOT LINEAR

provides insight to ecological problems -pestasides in crops

organism population-same species community-different species ecosystem- community+abiotic biome biosphere-all living things

biotic and abiotic factors abiotic-minerals,water,soil,air,light, rocks
