The solutions in the two arms of a u-tube are separated by a membrane that is
impermeable to glucose and sucrose. on side a, you have 1 m glucose and on
side b. you have 2 m sucrose. the temperature is 22 °c and it is an open system.
2 calculate the water potential of each arm of the u-tube. use the
formulas and show your work
a: 1m
glucose
semipermesble
membrane
b: 2m

b. which way will water flow?

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.

Explain why biological control methods are generally environmentally superior to chemical pest control methods.
