Major science
| Question | Answer |
|---|---|
| Organism | A living thing made up of two me or more cells that can perform all the processes needed for life. |
| Tissue | A group of similar cells that are organized to perform a specific function |
| Organ | |
| Organ system | A group that of organs that work together to perform body functions |
| What common traits would models of different unicellular organisms share? | They would all have one cell with smaller parts that do different jobs within the cell |
| What question can a biologist ask to determine if an object is living? | Is the object made up of cells? |
| Which structure surrounds cells? | Cell membrane and cell wall |
| What 2 features do eukaryotes have that prokaryotes do not have? | |
| Cardiac muscle cells | Specialized for contraction. The structure of protein fibers in the cell allows it to stretch and contract |
| Cardiac muscle cells | branch and connect to each other to form cardiac muscle tissue. Special junctions where the cells connect allow all the cells in the tissue to contract at the same time. |
| The heart | An organ in the circulatory system. The many cells stretching and contracting together make the heart stretch and contract, pumping blood as it changes shape |
| Skeletal muscle tissue | Made up of muscle cells organized into stretchy fibers |
| Nervous tissue | Remember food sources |
| Cell | The smallest unit that can be said to be alive |
| Paramecium | An organism made up of a single cell. |
| Cilia | Tiny hairlike structures surround the cell |
| Circulatory system | Delivers nutrients and oxegyn to all the cells in the body. It carries carbon dioxide and other waste products away from the cells |
| Muscular system | Moves bones causes the heart to beat and moves food through the digestive system |
| Respiratory system | Takes in oxygen and releases carbon dioxide as we breathe |
| Skeletal system | Supports the body protects organs allows movement and makes blood cells |
| Nervous system | Controls body movement and coordinates communication between the brain and the environment |
| Digestive system | Breaks down food into essential nutrients and expel solid waste from the body |
| Camouflage | Blending into the environment |
| Homeostasis | The process by which the inside of the body maintains stable conditions |
| Feedback | A cycle of events in which information from one step controls or affects a previous step |
| Positive feedback | Occurs when the body activates processes that increase or reinforced the change |
| Negative feedback | Occurs when the body senses, a change and its internal environment and activates processes that will slow or prevent the change |
| Sensory receptors | Help an animal gather information about its environment |
| Mechanical receptors | Detect pressure movement and tension |
| Chemical receptors | Detect chemical signals such as odors and tastes |
| Electromagnetic receptors | Detect, electromagnetic radiation, such as light |
| Frontal lobe | It’s the boss it can coordinate planning organization, behaviors, and emotions |
| Parietal lobe | Processes sensory information related to taste temperature and touch |
| Temporal lobe | Associated with hearing language and old factory senses |
| Occipital lobe | Involved in their reception of visual stimuli |
| How much damage to the temporal lobe of the brain affect a person which receptor messages would be affected | It will affect the temporal lobe messages from chemo receptors in the nose and mechanical receptors in the ears might not be processed |
| Behavior | The set of actions taken by an organism in response to stimuli |
| Memory | Information can be stored in the brain |
| Butterflies have membranes on different parts of their bodies that vibrate in response to waves in the air which type of sensory input are these membranes transmitting | Sound |
| Which other body system works with the skeletal system to help provide movement | Digestive system muscular system respiratory system |
| The skin is made up of several tissue types. Therefore, the snake skin is an example of a. | Organ |
| Which of these plant body functions requires interaction between the root and shoot system | Getting water to all parts of the plant, moving nutrients throughout the plant |
| Spiracles | Outside air through paired holes in the insects body segments |
| Trachea | Insect exchange gases with their environment through internal air tubes called |
| Zoology | The study of animals |
| Nervous tissue | Functions as a messaging system |
| Epithelial tissue | Protect informed boundaries and is found in Oregon such as skin |
| Connective tissue | Including bones and blood holds part of the body together and provides support |
| Muscle tissue | Provides movement |
