Bacteria and virus
| Question | Answer |
|---|---|
| Why are viruses considered to be nonliving | they are not cells, and viruses don't use energy to grow or to respond to their surroundings. |
| what is th basic structure of a virus | the virus is made up of a outer protein coat and genetic material inside. |
| how do viruses multiply | The genetic material directs the cell to produce the virus's proteins and genetic material. These proteins and genetic material are then assembled into new viruses. |
| what is a virus | A small, nonliving particle that invades and then reproduces inside a living cell |
| what's a host | an organism that provides a source of energy or a suitable environment for a virus or for another organism |
| what are parasites | an organism that lives on or in a host and causes harm to the host |
| what is bacteriophage | A virus that infects Bactria |
| why are Bactria cells different from all other organisms' cells | Bactria are prokaryotes. The genetic material in their cells is not contained in a nuleus. |
| what are the positive roles that bacteria play in people's lives | Bacteria are involved in fuel and food production, environmental recycling and cleanup, and the production of medicines. |
| what is cytoplasm | The region of a cell located inside the cells membrane ( in prokaryotes) or between the cell membrane and nucleus ( in eukaryotes) ; contains a gel-like material and cell organelles |
| what are ribosomes | A tiny structure located in the cytoplasm of a cell where proteins are made |
| what is flagellum | A long, whip like structure that extends out through the cell membrane and cell wall. |
| what is binary fission | A form of asexual reproduction in which one cell divides to from two identical cells. |
| what is asexual reproduction | The reproductive process involves only one parent and produces offspring that a identical to the parent. |
| what is sexual reproduction | The reproductive process that involves two parents who combine their genetic material to produce a new organism, which differs from both parents |
| what is conjugation | The process in which a unicellular organism transfers some of its genetic material to another unicellular organism. |
| what is respiration | the production of offspring that are similar to the parents. |
| what are endospores | A small, round, thick-walled,, resting cell that forms inside a bacterial cell |
| what are decomposers | an organism that breaks down large chemicals from dead organisms into small chemicals and returns important materials to the soil and water. |
| what are the two kingdoms of bacteria. | Archaebacteria and Eubacteria |
| how does bacteria reproduce and survive | when bacteria have plenty of food, the right temperature, and other suitable conditions, they thrive and reproduce frequetly. |
| How do infectious diseases spread from person to person | through contact with either an infected person, a contaminated object , an infected animal, or an environmental soure |
| What is infectious disease | An illness that can pass from one organism to another. |
| what are antibiotics | A chemical that can kill bacteria without harming a person's cells. |
| what is a vaccine | a substance that stimulates the body to produce chemicals that destroy viruses, bacteria, or other disease-causing organism |
| what is toxin | A poison that can harm an organism. |
| how can infectious diseases be treated or prevented | get a vaccine |
