| Question | Answer |
|---|---|
| ellsshare? | Cellular organizationcontain similar chemicals,use energy,respond to surrondings,reproduce,growth and develop |
| All organisms are made of one or more what? | Cells |
| DNA provides instruuctions for making which type of molecules? | Protiens |
| What are 3 examples of stimuli. | Changes in temperature,light,and sound |
| Provide an example of how your body maintains homeostasis. | 1.Drinking water, 2.Sweating helps your body maintain a stead body temperature,when sweat evaporates it cools your body |
| What are two ways organisms can reproduce? | Asexual and sexual |
| What are the basic needs of almost every organism? | Water,food,living space,and stable internal conditions |
| What is the difference between a producer,a consumer,and a decomposer? | Producer-can make food,Consumer-can't make food,Decomposer- |
| What is the difference between an autotroph and a heterotrophy? | Autotroph-can make it's own food,heterotrophy-can't make it's own food |
| What is the difference between terrestrial and aquatic organisms? | Terrestrial-land,aquatic-water |
| Name examples of each-a producer,a consumer,and a decomposer,autotroph,heterotroph. | Producer-grass,Consumer-caterpillars,Decomposer-insects,Autotroph-plants,Heterotroph-animals |
| Cells of all organismsa are made up mostly of what? | Water |
| What purpose does water and food serve an organism? | Water-helps them survive,food-gives them energy |
| What can limited resources lead to? | They can run out |
| What are the 2 tiny building blocks everything,living or nonliving is made up of? | Cells |
| What is an element? | Any substance that can not be broken down into a simpler organism |
| What are the main elements found in living things? | Oxygen and Hitrogen |
| Two or more elements joined together form what? | A compound |
| How does a molecule differ from a compound? | Molecule-smallest unit in a compound,Compound-2 or more elements joined together |
| What is the difference between an organic and inorganic compound? | Organic-has carbon,inorganic-doesn't have any carbon |
| Molecules of protein,carbohydrates,lipids,and nucleic acids are essential to what? | All living things |
| Provide an example of a protein,carbonhydrate,lipid and nucleic acid. | Protein-spider web,carbonhydrate-sugars,lipid-fats,nucleic acid-DNA & RNA |
| What are the subunits that make up molecules of proteins,carbonhydrates,lipids,and nucleic acid. | |
| Why do scientists classify organisms? | To organize living things into groups so the oragnisms are easier to study |
| What are the 8 major levels of classification? | Domain,kingdom,phylum,class,order,family,genus,and species |
| What is the order of the 8 major levels of classification from largest to smallest? | Domain,kingdom,phylum,class,order,family,genus,and species |
| How are the organisms placed into domains and kingdoms? | Based on their cell type,their ability to make food,and the number of cells in their body |
| What are the names of the 6 kingdoms? | Prokaryotes,archaebacteria,protists,fungi,plants,and animals |
| What is the difference between Archaebacteria and Eubacteria? | |
| What is the difference between a prokaryote and a eukaryote? | Prokaryote-organism whose cell lacks a nucleus,eukaryote-organism with cells that contain nucleus |
| What is a nucleus? | A dense area in a cell that contains nucleic acids-the chemical instructions that direct the cell's acticultes |
| Are bacteria prokaryotes or eukaryotes? | Prokaryotes |
| Are organisms in the Kingdoms Protista, Plantae, Fungi, and Animalia prokaryotic or eukaryotic? | Eukaryotic |
| Are organisms in the Kingdoms Plantae, Fungi, and Animalia simple or complex multi-cellular organisms? | Eukaryotic-Complex |
| Know the importance of using a two-part scientific name, and how to write it correctly. Give an example | Binomial Nomenclature-a naming system used by Carolus Linnaeus.Two names for each type of organism |
