| Question | Answer |
|---|---|
| List each characteristic of Life. | cells, responds to stimulus, homeostasis |
| define cells | cells are membrane covered structures that contain every material needed for life |
| explain the difference between multicellular and unicellular | multicellular: more than one cell unicellular: one cell |
| define stimulus and list eight examples | Stimulus is a change in an organism's environment that affects its activity ex: food,touch,darkness,light,temperature,noise,smell,and taste |
| define homeostasis | homeostasis is to maintain a stable internal environment |
| Explain why sexual reproduction results in offspring that are genetically unique. *has to do with the number of parents and DNA | there are two parents, so the DNA is shared from both making the child unique |
| How many parents are involved in asexual reproduction? Is the offspring identical or different from the parents? Why? | 1:the DNA is identical because there is only one set of DNA given. |
| When organisms grow and develop what does that mean the cells are doing? | It means that the cells are increasing in number and change |
| Why is food a necessity? | it is used for energy, to repair cells, and for making new cells |
| Define Producer | uses the sun's energy to make food and function |
| Define consumer | eats producers or other consumers for energy |
| define decomposer | they get energy from breaking down nutrients in animal waste and/or dead organisms |
| why is water a necessity for life? | it is needed for reactions within the cells |
| why is oxygen a necessity for life? | it is needed for reaction within the cells |
| What are the four necessities of life? | food, water, oxygen, and space for living |
| Define spontaneous generation | the belief that living comes from non-living things |
| define biogenisis | the belief that living comes from living |
| EXTRA CREDIT-----explain Redi's experiment with rotten meat and how it disproved spontaneous generation----- | -3 jars;netted, no lid, sealed -he found that the flies came from the layed eggs that were on the meat not the meat itself |
| What did Linnaeus develop and how was it organized | Linnaeus developed a system grouping together organisms based on similar structures. |
| how is modern classification organized | it is organized by using similar structures to group organisms |
| How does the modern classification system start to divide organisms?Are the groups large or small at first and do the organisms in the group have a lot or a little in common? | They start to divide organisms by using broader to more specific groups. They start large and have less in common and when they get smaller they become more in common. |
| What is the classification order? What is the trick to remember the order? | Kingdom, Phylum, Class, Order, Family, Genus, Species KING PHILLIP CRIED OH FOR GOSH SAKES |
| Which group has the most in common and which group has the least?Which group can breed and produce offspring? | Species have the most in common and the kingdom has less in common. The species can reproduce, but kingdoms can not. |
| define binomial nomenclature | a 2 word naming system; uses scientific names (genus and species) |
| What two names from the naming system are in an organism's scientific name and in what order? | genus, species |
| What are the three scientific advantages to using scientific names? | They are specific, avoid confusion, and they provide a universal language. |
| Define dichotomous key. Explain how a key is created. | It is a detailed list of identifying characteristics that include the scientific name. They are arranged in steps with two descriptive choices at each step. |
