| Question | Answer |
|---|---|
| what characteristics do | all living things have cells, have DNA, reproduce, have chemicals, and use/need energy. |
| multicellular organisms have two or more cells, are more complex, specialized to different tasks, and the cells work together. unicellular organisms have one cell, and are more simple. | |
| the difference is that sexual creates an offspring with a combination of DNA from two patents, and asexual creates an identical offspring to one parent. | |
| dissolved and transports substances easily. | |
| provide cells with energy, and are made of sugars (simple or complex). | |
| used for building cells, and provide structure. | |
| provides instructions to carry out the functions of life. | |
| all living things need water, food; space, and homeostasis. | |
| homeostasis means to maintain a stable environment for living, and there are many ways to do this. | |
| stimulus: fire alarm goes off/ response: jump up, adjust to sound. stimulus: light turns on/ response: eyes widen and adjust stimulus: touch something hot/ response: pull back, treat hand and get it back to normal temperature. | |

| domain. | |
| species | |
| domain, kingdom, phylum, and class. | |
| archaea are unicellular organisms, do not have a nuclei, are microscopic, and live in harsh environments. | |
| bacteria are unicellular, do not have a nuclei, are found all around us, and are microscopic. | |
| eukarya have a nuclei and are multicellular. | |
| πΎππ‘π«ππ©ππ πππππ£π©ππ. | |
| πΎππ‘π«ππ©ππ is the genus. | |
| they are in the eukarya. | |
| can move around, heterotrophs (ex. amoeba, giardia) | |
| mostly autotrophs, some can move around, but some are attached (ex. red algae, dinofagellates) | |
| heterotrophs (ex. slime molds and water molds) | |
| bacteria and viruses are similar because they are both small, both have DNA and protein, and they both reproduce. | |
| bacteria and viruses are different because bacteria are living and viruses are not. | |
| viruses are not considered a living thing because they lack most of the characteristics of life. they do not use food for energy or to grow, do not respond to surroundings, and cannot reproduce without a host. | |
| what is the difference between asexual and sexual reproduction? |
