11.calorie:the unite to measure the amount of energy in food
1) DNA: It is located in the cells of organisms; it controls what the cells and organisms will become.
2) Density:the amount of mass in a certain volume
3.digestive system:the body system where foodis mechanically digested in the moth,and chemically digested in the stomach,then nutrients are absorbed into the blood in the small large intestines
1) Eukaryotes: Organisms that have a nucleus in their cells.
2) Ecosystem: A system of biotic and abiotic things that interact with each other in an environment
1) Flagella: Whip-like structures that help the cell move.
2. Fat : fats are also nutrients that provides energy and helps the body digest the certain vitamins but can be also unhealthy if one eats too much.
1) Genes: Pieces of DNA that control a certain trait.
2) Galaxy: a huge group of stars.
3) Gravity:an attractive force between two objects
1) Hypothesis: An educated prediction that can be tested by using an experiment. Also, it is a prediction about what will happen in an experiment.
2) Heterotroph: a organism that eats
3) Habitat: A place where there is shelter and food
4) Humidity: amount of moisture in the air (measured in %)
1) Inference: Something that you can not observe, but that you can figure out based on your observation.
1) Metric system: A system of measurement used in every country except 3 of them, and used by all scientists.
2) Meter: A metric unit for the measuring length based on the size of the Equator.

7) Meteoroid: a meteor that lands on earth’s surface
8) Mass:the amount of matter in an object
9)Metabolism:how quicly your body uses calories that you eat
1) Nucleus: cell part that controls most cells
2) Nebula: a cloud a of gas in space
1) Organism: A living thing
1) Prokaryotes: Organisms that do not have a nucleus
