glucose, a carbohydrate, readily dissolves in your bloodstream. cholesterol and
triglycerides-both lipids--are packaged inside the waterproof spaces of lipoproteins
so they can enter the bloodstream. use the molecular models from the activity along
with those in your textbook to compare the chemical compositions and structures of
glucose, cholesterol, and triglycerides. construct an explanation for how the
compositions and structures of these carbon-based molecules are related to the way
they interact with your bloodstream.

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?
