The shape of the nucleus is maintained by
a. the nucleolus.
b. the nuclear lamina.
c. the nuclear envelope.
d. the endoplasmic reticulum.
its not pls

Answer : The correct answer is- B)

The nuclear lamina.

The nuclear lamina is basically a fibrillar network of proteins that is present close to the inner membrane of nucleus.

It is mainly composed of intermediate filament lamins and proteins that are associated with lamins.

Nuclear lamina provides mechanical support to the nucleus and thus maintains the shape of nucleus.

Apart from this, it also regulates the process of DNA replication and division of cell.

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.
