Tropomyosin is a rod-shaped protein with a mass of 70 kDa and a sedimentation coefficient of 2.6S. Hemoglobin is a spherical protein with a slightly smaller mass of 65 kDa, but a much higher sedimentation coefficient of 4.31S. Which property of tropomyosin accounts for its slow sedimentation?

a. high particle density
b. elongated shape
c. high mass
d. low partial specific volume
e. overall net charge

c

explanation:

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.
