Which of the following best describes the goal of using gene therapy to treat children with Severe Combined Immunodeficiency Disorder (SCID)? Gene therapy -
collects infected cells and converts them to cells without the SCID gene.

allows children to use fewer medicines to treat their SCID over their lifespan.

prevents children with SCID from passing the disease to their offspring.

provides healthy cells that replace defective cells in the bone marrow of children with SCID.

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.

the correct answer, according to e2020, is the second choice there is an occluded front in region a and a cold front in region b.

if you add everything up correctly you should get 69 i got this because 50 plus 19 is it
