The yellow fever virus replicates in lymph nodes and in other immune system cells. how does it arrive in lymph nodes

The yellow fever virus replicates in lymph nodes and in other immune system cells, the yellow fever pathogens reach the lymph node of humans from bite through mosquitoes.

Explanation:

The yellow fever is a viral disease that occurs for a short time, this disease is spread to the humans from mosquito's. Once it enters the blood stream through the bite of a mosquito it directly enters the blood stream and gets caught in the lymph nodes, these lymph nodes serve as sites for multiplication of these organisms.

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.

blue stars have the highest surface temp

stellar distances are usually expressed in light-years

the measure of a star's brightness is called magnitude

hope this !
