| Question | Answer |
|---|---|
| 3 particles of atom | neutron, electron, proton |
| space surrounding nucleus | electron |
| covalent bonds are | sharing of electrons |
| energy neeeded to get reaction started is | activated energy |
| cellular respiration occurs in plants and | animal cells |
| main function ofo proteins are | build muscle and bone, help fight disease, control rate of reactions |
| which compunds are composed of amino acids | proteins |
| the nucleus is made up of | proton and neutron |
| channels and pumps are made of | proteins |
| the enclose dna in a nucleus is | eukaryote |
| whic substance act as chemical messengers | hormones |
| what controls what goes in and out of a cell | cell membrane |
| who named cells | Robert Hooke |
| primary function of the cell wall is | support and protect |
| proteins using coded instuctions are | ribosomes |
| group of species that live in same places is called | population |
| why do birds fly in winter | response to their environment |
| which swquence correctly traces the path of a protein in the cell | ribosome, ER, golgi |
| what allowed the discovery of cells | microscope |
| Na=ions enter cells by | finding and passing through a pump |
| which organelle converts the chemical energy store in food | mitochondria |
| what happens at equilbrium, during diffusion | move back and forth |
| Pinocytosis involves the transport of | fluid into a cell |
| a factor that change of independent is the | dependent variable |
| Rule or principle | scientific law |
| process of gathering information through senses | observation |
| when designing an experiment, the first step is to | state the problem |
| a measure of earth's gravitational pull on matter is | weight |
| explanation of a event, repeated observations | theory |
| a standard for comparison that helps to ensure that the experiment | control |
| a idea, event, or object | model |
| temperature change of a material over time, temperature change is the | dependent variable |
| another term for technology is | applied science |
