If you're a boss in biology, .

36. composting is the process of breaking down organic materials under controlled conditions. a student set up three compost bins, one of which is shown in figure 20-6. into each compost bin, he added an identical combination of wood shavings, shredded paper, nitrogen, and bacteria. he mixed the materials in each bin and adjusted the insulation around the bins to maintain daily target temperatures. he then monitored the temperature, moisture, and amount of decomposition of the compost in each bin over an eight-week period. some of his data are shown in the graph.

at the end of eight weeks, the student found that the materials in compost bin a had undergone the most decomposition. the materials in compost bin b had decomposed the least. use the graph in figure 20–6 to explain these results.

Scientific thinking: what clues about biology might road kill provide?

Be in this im starting a with you so if you want you can get a partner for this. but basically im going to assign you guys a biome and you have to have a big sheet paper and you will turn it into 4 squares. the top right square is will be a drawing square for a drawing you will make of your biome. the top left square is about the biomes plants and drawings of them. the bottom left square is about the biomes animals. the bottem rights square is about the description of the biome. leave a comment or an answer and i will assign biomes. if your request one thats the one you get. send me a link to the project and i will grade ! im not a teacher btw.

Which statements best describe the differences or similarities between a comparative investigation and an experimental investigation? check all that apply. experimental investigations are best for showing cause-and-effect relationships, while comparative investigations do not necessarily show this type of relationship. comparative investigations are often impractical and unrealistic, while experimental investigations are the most practical and realistic kinds of investigations. comparative investigations allow for the use of a wide range of variables but do not have a control group, while experimental investigations involve variables that can be controlled. both experimental investigations and comparative investigations are designed to answer scientific questions. both experimental investigations and comparative investigations focus on making observations rather than collecting new data.
