Gelatin is a protein that is derived from Colligan which is found from the bones skin and connective tissue of animals to investigate ability various enzymes to digest gelatin in a group of students set up an essay involving camera film camera phone contains gelatin and appears black when exposed to light but turns clear as the gelatin gets broken down the student incubated pieces of exposed camera film and they test tubes each containing one of three different enzyme solutions Chipsin lipase or amylase as indicated in figure 1 the student records the time it took for the enzymes to digest the The gelatin in each tube turn in the film from black to clear which would be the most appropriate control for this experiment

Most scientific questions are based on opinions. hypotheses. observations. experimental data.

This map shows how climate change might affect precipitation patterns in the great plains of the united states by the end of this century. brown shoes a decrease in percipitation, and blue shows an increase. the maps differ based on the predictive levels of green house emissions. the maps shows that northern area should get a. more pracipations regardless of emmissions b. less pracipation, regardless of emmissions levels c. more precipitation, but only when emission levels. southern areas show a. more pracipations regardless of emmissions b. less pracipation, regardless of emmissions levels c. more precipitation, but only when emission levels. to use these maps to prepare for natural disasters in the great plains, scientist need to ask? a. how many tons of emissions were used at the basis of the map. b. which types of fossil fuels are used in the great plains c. if you think the above is wrong it's probly c the question is cut off
