The solutions in the arms of a u-tube are separated at the bottom of the tube by a selectively permeable membrane. the membrane is permeable to sodium chloride but not to glucose. side a is filled with a solution of 0.4 m glucose and 0.5 m sodium chloride (nacl), and side b is filled with a solution containing 0.8 m glucose and 0.4 m sodium chloride. initially, the volume in both arms is the same.

a. a decrease in the concentration of nacl and glucose and an increase in the water level.

b. a decrease in the concentration of nacl, an increase in water level, and no change in the concentration of glucose.

c. no net change in the system.

d. a decrease in the concentration of nacl and a decrease in the water level.

e. no change in the concentration of nacl and glucose and an increase in the water level.

the answer is otpion c) understanding

he wants to be heard one more time. he wants to be understood. he needs the truth one more time.

tsd is temerature dependent sex determination.

tsd: it is a type of environmental sex determination in which the temperature experienced during embryonic/ larval development (ambient temperature for development) determine the sex of the offspring.

crocodile displays the tsd where the ambient temperature of the developing egg determines the individual's sex. for example in the american alligator's eggs, incubation at 33 ºc produces mostly males, while incubation at 30 ºc produces mostly females. so if the american alligator's egg will get the ambient temperature (33 degree celcius)during embryonic development from egg, the offspring will be male and same for the female sex determination.
