Which of the following cellular materials is solely composed of dna and proteins? golgi complex mitochondria ribosomes chromosomes

chromosomes

Modification of protein is done by the Golgi apparatus of the cell and not the nucleus. The nucleus simply has the blue print of proteins and releases these blue prints to mRNA which transports the prints out to the ribosomes where they are read and used to synthesize or make the protein.Once a protein has been made, it is packed into a vesicle which is a "shipping envelope" for a cell. The vesicle moves to the Golgi apparatus which receives it and enzymes within the apparatus modify the vesicle contents, that is the protein, to its final form. The protein is then repacked into a new vesicle which then migrates from the Golgi apparatus to the cell membrane and releases the protein to the outside of the cell.

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.
