| Question | Answer |
|---|---|
| Life Science | is the study of living things |
| Scienticfic Method | is often described as a series of steps that is used to answer a question to solve a problem |
| Hypothesis | is a possible answer to a question |
| Controlled Experiment | a test only one factor at a time |
| Variable | All of the factors fo the control group and the experiment where all groups are the sameexcept for one the one factor that is different |
| Theory | a unifying explanation for a broad range of hypotheses and observations that have been supported by testing |
| Technology | is the use of knowledge tools, and materials to solve problems and accomplish tasks |
| Compound Light Microscope | is made up of three main parts |
| Electron Microscope | tiny particles of matter called electrons are used to produce magnified images |
| Area | is a measure of how much surface an object has |
| Volume | Is the amount of space that something ocupies |
| Mass | is the amount of matter that makes up an object |
| Temperature | is a measure how hot or cold something is |
| Cell | is a membrane-covered structure that contains all of the materials necessary for life |
| Stimulus | a change in an organism enviroment that affects the activity of the organisms |
| Homeostasis | The maintenance of a stable internal enviroment |
| Asexual Reproduction | a single parent produces offspring that are indentical to the parent |
| Sexual Reproduction | almost always requires 2 parents that will share characteristics of both parents |
| DNA | the cells of all living things contain a special molecule |
| Heredity | the transmission of charateristics form one generation to the next |
| Metabolism | is the total of all of the chemical activities that it proforms |
| Consumer | they eat other organisms |
| Decomposer | are organisms that get their food by breaking down the nutrients in dead organisms or animal wastes |
| Producer | organisms that make their own food usuall by using the energy form sunlight to make sugar |
| Protein | are large molecules that are made up of subunits called amino acids |
| Carbohydrates | are a group of compounds made of sugars |
| Phospholipids | are the molecules that form much of the cell membrane |
| Lipids | are compounds that can not mix with water |
| Nucleic Acids | are compounds made up of subunits called nucleotides |
| ATP | is the major fuel used for all cell activities that require energy |
| Tissue | a group of cells that work together to perform a specific job in the body |
| Organ | the group of tissues that perform a specific job |
| Organ System | organs work together in groups to perform particular jobs those groups are the organ system |
| Organisms | Anything that can live on its own |
| Multicellular | it means you can only exist as a group of cells |
| Populated | a group of organism that are of the same kind and that can live in the same area |
| Community | Two or more populations living in the same area |
| Cell Membrane | a barrier between the inside of the cell and the cells enviroment |
| Organelles | all cells have chemicals and structures that enables the cell to live, grow, and produce that structure is called a organelle |
| Cytoplasm | the fluid and almost everything in it are collectively |
| Nucleus | a membrane covered organelle that holds the cells DNA |
| Prokaryotic | Cells that do not have a nucleus |
| Eukaryotic | cells that have a nucleus |
| Bacteria | Prokayotic cells are also called bacteria |
| Cell Wall | Provides strength and support to the cell membrane |
| Ribosomes | are the smallest but most abundant organelles |
| Endoplasmic Reticulum | is a membrane-covered compartment that makes lipids and ther materials for use inside and outside the cell |
| Mitochondria | ATP can be made at several locations in eukaryotic cells, but most of it is produces at bean-shaped organelles |
| Chloroplast | Plants and alegea have an addition for all kinds of energy-converting |
| Golgi Complex | When proteins and other materials need to be processed and shipped out of a eukaryotic cell, the job goes to and organelle |
| Vesicles | all eukaryotic cells have membrane covered compartment |
| Vacuole | most plant cells have a very large membrane-covered chamber |
| Lysosomes | are special vesicles in animal cells that contain enzymes |
| Diffusion | is the movement of particles from an area where their concentration is low |
| Osmosis | the diffusion of water theough the cell membrane is so important to life processes that it has been given a special name |
| Passive Transport | is the diffusion of particles through the protein |
| Active Transport | is the movement of particles through proteins against the normal direction of diffusion |
