homeostasis maintanenece of consistant enternal state
sexual reproduction reproduction with sex cells from 2 parents and traits from both passed on
assexual reproductuon 1 parent with no sex cells producing identical offspring
heredity passing of genetic traits form parents to offspring
metabolism sum of all chemical processes that occur in an organism
producer organism that can make its own food
consumer organism that eats other organisms or organic matter
decomposer gets energy by breaking down dead organisms or waste and obsorbing nutrients
protein molecule made uyp of amino acids and needed to build and repair body structures and regulate processes in the body
carbohydrate class of energy giving nutrients include sugars, starches, fiber and contains carbon, hydrogen, and oxygen
lipid biochemical, doesnt dissolve in water
phospholipid contains phosphorus; structural component in cell membranes
ATP molecule acts as main energy source for cell processes
nucleic acid molecule made up of subunits called nucleotides
what are the 6 characteristics of living 1:made of cells, 2: sense respond to change, 3: they reproduce, 4: they have DNA, 5: they use energy 6: they grow and develop
what are the 4 needs of every organism food, water, air, shelter
about how long can humans survive without water about 3 days
air is a mixture of gases including oxygen and carbon dioxide
what is a chemical process when most living things use oxygen releasing energy from food
plants need carbon dioxide and oxygen
how do plants convert sunlight into energy photosynthesis
how does the limited amount of space on earth affect organisms make organisms compete for what they need
what are 2 things food gives organisms energy and raw materials needs to carry on life processes
what are 2 ways organisms use nutrients from food replace cells and build body parts
what eats living organisms or organic matter consumers

what do plants use to make glucose? photosenthysis
how do animals break down food using oxygren cellular respiration
the process in which particles move through a membrane from a low to high concentration active transport
what cells form a cell plate in the cell cycle plant cell
why is osmosis important to cells cells are filled with fluid thats mostly water
when water diffuses ina nd out of cells it is called osmosis
fermentation occurs when a cell cant get oxygen
when does a recessive trait show up in the second generation
when a plant is able to self pollinate when a plant has both male and female reproductive system
materials have to pass through what to get in and out of an organisms cell cell membrane
when a human feels hungry its becasue they need energy
what type of cell contains more DNA eukaryotic cells
what is the ratio for dominant to recessive traits 3 to 1
2 forms of a gene, 1 from each parent, are called alleles
what are punnent squares used for to organize possible offspring combination
what is a plant with either 2 recessive or 2 dominant traits homozygous
what is genetic makeup formed from both inherited alleles together genotype
what is the process of chromosome separation mitosis
