The rna components of ribosomes are synthesized in the
cytoplasm
nucleus
nucleolus
endoplasmic reticulum

Nucleus

Explanation:

In eukaryotic cells the synthesis of RNA occurs in the nucleus. This process is called transcription and the mechanism is mediated by RNA polymerase. The RNA synthesized can be messenger RNA, transcriptional RNA or ribosomal RNA among others. RNA polymerase to synthesize RNA has to read the DNA chain that is that is always inside the nucleus when transcription occurs.

white blood cells or wbc s are mainly 2 types-

1.agranulocytes

2.granulocytes

the monocytes or macrophages of agranulocytes , dendritic cells which are accessory leucocytes, and b cells which is one type of lymphocytes   identify the antigens present on the pathogen's surface. these three cells are called antigen presenting cells(apc) which are phagocytes and destroy the antigens by secreting antitoxins. besides this leukocyte is always plays vital role in the immunity of the body.

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.
