Biological Processes
Biological processes and systems
| Question | Answer |
|---|---|
| atom | most basic level of organization |
| Levels of organization | atom, molecule, cell, tissue, organ, organ system, organism, population, community, ecosystem, biome, biosphere |
| Nervous tissue | reacts to stimuli and transmits throughout the body |
| Muscular tissue | is specialized to contract and allow for movement of the body |
| Epithelial tissue | lines the surface of organs and the body cavities (holes) |
| Connective tissue | most widespread tissue in the body; specialized to connect and support other tissues; ranges form bones, to blood, to fat tissue |
| Are atoms and molecules living? | no |
| Population | group of organisms of the same species living in the same area. |
| Community | multiple populations living in a designated area. |
| Ecosystem | all the living and nonliving things in an area. |
| Different biomes: | marine, freshwater, desert, forest, grassland and tundra |
| Marine biome | salty water; makes 75% of the earth's surface; dominated by algae and plankton |
| Freshwater biome | lakes and streams; plant communities vary; algae-lakes and aquatic plants and trees (cypress)- marshes |
| Desert biome | low level of rainfall + low population densities; dominated by cacti and other drought tolerant plants. |
| Forest biome | dominated by trees; sufficient rainfall + nutrients to support large plants |
| Grassland biome | dominated by grass; not a lot of water and nutrients to support large plants |
| Tundra | temperature very cold (arctic); sparsely populated; dominated by shrubs and smaller vegetation. |
| mutation | change in the nucleotide sequence of DNA |
| molecule | smallest unit of most compounds that displays all the properties of that compound |
| organelle | specialized structure that performs important cellular functions within the cell |
| cell | basic unit of all forms of life |
| tissue | group of similar cells that perform a specific function |
| organ | group of tissue that work together to perform closely related functions |
| organ system | group of organs that work together to perform a specific function |
| organism | a living thing |
| biosphere | part of the earth in which life exists including land, water, and air or atmosphere |
| excretory system | eliminates waste products from the body |
| reproductive system | reproduces gametes |
| digestive system | breaks down food |
| immune/lymphatic systems | protects the body from disease |
| nervous system | recognizes and coordinantes the body's response to changes. |
| circulatory system | transports oxygen to cells |
| muscular system | produces voluntary movement |
| respiratory system | brings in oxygen for cellular respiration |
| skeletal system | protects internal organs |
| endocrine system | controls growth and metabolism |
| homeostasis | maintaining a stable internal environment |
| feedback inhibition | negative feedback; anti-stimulus ex: sneeze |
| why is liver important to homeostasis | regulates substances in our body like glucose and converts dangerous substances into compounds that can be removed from out body |
