- energy, food, water, oxygen, living space, homeostasis
- element
- pure substance that cannot be broken down into simpler substances by ordinary means
- nucleic acids
- DNA, RNA // very large compounds that store information that helps body make proteins it needs
- cold-blooded
- changing body temperature with environmental changes
- digestion
- process by which food is broken down into simpler substances
- multicellular
- many cells
- primary source of energy
- the sun
- stimulus
- any change in environment
- DNA
- all organism's traits and characteristics
- development
- process of change that occurs during organism's life to produce more complex organism
- cells
- basic building blocks of living things
- sugar
- stored as starch
- respiration
- process by which living things take in oxygen to use to produce energy
- basic building blocks of all organisms
- cells
- enzymes
- special proteins that act as catalysts-speed up/slow down chemical reactions
- building material of cells
- lipids and proteins
- warm-blooded
- animals that maintain fairly consatnt temperature
- food
- source of energy needed for growth, development, repair of cells and body parts
- RNA
- reads the DNA message and guides the protien-making process
- characteristics
- made of cells, reproduction, respond to environment, perform complex chemical acts (metabolism), movement, grow and develop (lifespan)
- without water
- all living things die within a few days
- organism
- living thing
- fats and oils
- flavor enhancers
- oils
- liquid at room temperature
- lipids
- fats and oils
- excretion
- process of getting rid of waste materials
- organic compounds
- refers to life, contain carbon, hydrogen, oxygen, carbohydrates, fats and oils, proteins, enzymes, nucleic acids
- inorganic compounds
- may or may not contain carbon-most do not
- glucose
- simple sugar, budy uses to produce energy needed for life processes
- ingestion
- eating, taking in
- unicellular
- single-celled
- inorganic
- does not refer to life
- homeostasis
- ability to maintain fairly constant body temperature
- living space
- competition for limited supplies
- jobs of proteins
- growth and repair of body structures, build muscle, provide energy, provide oxygen to diferent parts of the body, fight germs, make chemical substances-hormones- thats start,stop,and regulate many body activities
- carbohydrates
- carbon, hydrogen, oxygen
- proteins
- carbon, hydrogen, oxygen, nitrogen, sulfur, phosphorus/building blocks of amino acids
- metabolism
- chemical activities of all living things
