A student set up an experiment to investigate osmosis as shown. The student used visking tubing which is a partially permeable membrane. The student put 25 cm of 20% sucrose solution into visking tube 1 and 25

cm of distilled water into visking tube 2. Both tubes were placed in a 5% sucrose solution and left for 1 hour.

Some technological solutions to problems like global warming meet the specific needs and situations of local communities. an example from india involves converting the solid waste from cattle into clean-burning fuel for cooking. this reduces the amount of greenhouse gases, specifically methane and carbon dioxide, released into the environment from wood fires. when evaluating the feasibility of implementing this solution, computer models are used to weigh costs against benefits. what factor is least likely to impact the decision on adopting this technology?
