Which kidney disease characterized by nephrotic syndrome, microscopic hematuria, and glomerular deposits of c3 complement and properdin is caused by an autoantibody called c3 nephritic factor? a. membranoproliferative glomerulonephritis type ii b. focal segmental glomerulosclerosis c. membranous nephropathy d. iga nephropathy e. acute postinfectious glomerulonephritis?

The answer would be A. Membranoproliferative glomerulonephritis type II. This is a disease caused by deposits in the kidney glomerular mesangium as well as in the basement membrane becoming thicker. In type II, most of the cases do not show a membranoproliferative pattern.

answer: carbon 14 can only be used to determine the age of the organisms that were once living, and igneous rocks are non living.

explanation:

carbon 14 dating is used to determine the age of the sample by estimating the amount of carbon 14 present in the sample and then comparing it with a reference standard.carbon 14 is a isotope of carbon which is radioactive and unstable. carbon 14 is assimilated by all plants and animals throughout their life from carbon dioxide. however, one the organisms die they stop this assimilation and the carbon 14 content starts to decrease.by knowing how much of carbon 14 is left in an organism after his death, one can estimate the age of the organism. the materials whose age can be estimated by carbon 14 method are the organic compounds. however, some inorganic compounds such as aragonite   shell can also be dated.however, if we consider the igneous rocks it is a non living component which never accumulated carbon 14 in it and thus, we cannot use carbon 14 dating method to estimate its age.
