Science
| Term | Definition |
|---|---|
| Hyper tonic | more solute |
| Hypo tonic | Less Solute |
| isotonic | balance |
| Active Transport | Movement of molecules from LOW TO HIGH concentration |
| when is energy required? | as molecules must be pumped against the concentration gradients |
| what are proteins that work as pumps | Protein Pumps |
| protein pump EX | the cell has carbon and has to get it out so protein pumps help force it out |
| Endo.and Exocytosis | mechanism by which very large molecules (such as food and wastes)get out of the cell |
| Endocytosis | food is moved into the cell |
| exocytosis | food is moved out of the cell |
| endocytosis and exocytosis | could go high to low concentration or low to high bu is called active transport as long as they use energy |
| phagocytosis | eating of food by the cell by endocytosis |
| endocytosis | wrap membrane around food |
| pinocytosis | drinkingf done by the cell |
| white blood cells | part of the immune system surround and engulf bacteria by endocytosis |
| organic compounds | contain carbon and hydrogen |
| strenuous | hard |
| viruses | its not normal to be born with them (HIV)identified by #s H1N1 H&N=meaning 1&1=to what strain |
| virus characteristics | made of pathogens |
| pathogens | make you sick |
| among the smallest biological particles that are | capable of causing diseases in living organisms |
| constructed of | compounds associated with cells |
| puzzle correlation | puzzle peaces have a certain piece that they connect to,a virus has a certain cell that it connects to |
| virus | connects to cell releases virus material into the cell |
| they are not alive | viruses |
| viruses are strands of | DNA or RNA chemical message. they tell the cell to do something that is not right |
| viruses are not | bacteria fungus protists plant or animal |
| viruses can not carry out | cellular functions |
| they have to do what to replicate | infect a cell and using the organelles and enzymes of the host cell |
| metabolism | controls us |
| you can only see viruses with | Electron Microscope |
| Screen Door EX | A virus wants to get in the cell but the cell does not want it to but the virus is so small it does anyway. |
| virus has ? sentential features | 2 |
| a virus has | a nucleic acid, DNA or RNA but not both |
| capsid | a protein coat surrounding the Nucleic Acid |
| the virus does what | it tricks the cell into making capsids.virus gives the code from RNA(HARDER TO RECOVER FROM)or DNA(EASIER TO RECOVER FROM) |
| virus analogy | gumball toy machine so in capsule of the virus has info like a gum ball toy machine |
| virus attacks sertan cells because | only serton cells make the proteins the virus wants so it attacks the host cell |
| virus takes what from the cell it attacks | the cell`s membrane |
| the proteins that the virus makes | burst out of the cell taking the membrane with them so the cell dies |
| envelope | membrane like structure on the outside of the cell |
| ex | influenza chicken pox HIV herpes simplex |
| some white blood cells | look for infected cells and kill them |
| flue infects | the lungs |
| polyhedral | many sides |
| helix | Spiral shape EX measles and tobacco mosaic virus |
| bacterial phage | it attacks bacteria and connects to bacteria and makes more viruses. |
| Viron | virus |
| Polymerase | sugar |
| Ion microscope | zooms two million times |
| HIV | wants the white blood cell to find it and the HIV kills the whit blood cell |
| Laten | effects the white blood cell and sits there |
| How many types of viruses are there | two |
| what are the two types of viruses | DNA and RNA |
| explain the DNA | Replicated in one of two ways; directly produce RNA that make new viral proteins; join with the host cell's DNA |
| explain RNA | Released into hosts cell cytoplasm; uses the ribosomes to produce new viral proteins; some are known as retro viruses |
| virus and living cells | take advantage of hosts cells nutrition and all other functions that occur in living things |
| viruses are called | parasite |
| active homework | the virus enters the cell replicates its self hundreds of times and then burst out of the cell destroying it starts making the cell make viruses |
| latent cycle | the virus DNA integrates with the hosts cells DNA and that cell helps create more virus DNA an environmental change may cause the virus. To enter lytic cycle and its reproducing infected scales. |
| how does the virus get from one place to the other | through body fluids |
| rabies | infects the spinal cord and the brain cells |
| HIV | effects the white blood cells |
| what happens in the lysogenic cycle | the virus reproduces by first injecting its genetic material indicated by the red line into the hosts cell genetic instructions. |
| vaccines | improves immunity to a particular disease |
| what are vaccines made from | weakened or killed forms of the microbe or virus |
| what does the vaccine stimulate | it stimulates the immune system to produce antibodies to recognize the agent as a foreign destroy it and remember it |
| how many functions does the skeletal system have | 5 |
| what are the skeletal system functions | 1.gives shape and support 2.muscles are attached to bone 3.minerals are stood in bone 4.minerals are stored in bone 5.protects major internal organs |
| how many body tissues are there | 4 |
| what are the body tissues | epithelial nervous muscle connective |
| what happens if there are no skeletal systems | the bones have nothing to attach to |
| why do we look the way we do | because of our skeleton |
| bones are stronger than what | steal |
| osteocytes | mature bone cells |
| osteoblast | deposit mineral in bone |
| osteoclasts | dissolve bone (break down bone) |
| yellow marrow makes what | white blood cells |
| red marrow makes | red blood cells |
| we are born with how many bones | 600 |
| we have how many bones NOW | 200 |
| bones formed together are | joints |
