Slime molds are one example of fungus-like protists. compare and contrast the two types of slime molds, their cell structure, and how they obtain nutrients.

The two kinds of slime molds are plasmodial slime molds or true slime molds and cellular slime molds.

True slime molds are a type of molds that are large hand are single-celled that have thousands of nuclei called plasmodium. These molds form when individual flagellated cells come together and fuse forming a large bag of cytoplasm that contains several diploid nuclei.

Cellular slime molds on the other hand are single-celled amoeboid protists. They undergo what is known as pseudoplasmodia wherein the individual mold will release a chemical signal then other single-celled molds will get attracted and turn into a swarm. As the swarm continues to grow it eventually becomes a multi-cellular slug. 

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.
