Two different organisms were studied in a carrying capacity study. one was a paramecium population that grew in a flask in a laboratory environment that spanned a period of 15 days. the other was a bear population in a forest that spanned a period of one hundred years. both populations grew exponentially for a short period of time until they both reached an equilibrium and population growth remained stable due to limiting factors. how might their numbers compare when studied? a) paramecium- 0 days/ 35 paramecium 5 days/250 paramecium 10 days/ 300 paramecium 15 days/ 40 paramecium bear- 0 days/ 2 bears 20 years/ 26 bears 40 years/ 230 bears 60 years/ 250 bears 80 years/ 252 bears 100 years/ 13 bears b) paramecium- 0 days/ 50 paramecium 5 days/100 paramecium 10 days/ 500 paramecium 15 days/ 900 paramecium bear- 0 days/ 2 bears 20 years/ 26 bears 40 years/ 230 bears

Which greenhouse gas is emitted when burn fossil fuels for energy? a. nitrogen b. oxygen c. carbon dioxide d. helium

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.
