The question is incomplete as it does not have the options which are:

a. mosses.

b. charophytes.

c. ferns.

d. gymnosperms.

e. flowering plants.

C. ferns.

Explanation:

In the given question, the characteristics of a newly identified species were provided which are:

1. Flagellated sperm: shows that it is either a bryophyte or pteridophyte

2. Dominant sporophyte: chances that it is a pteridophyte

3.The xylem and tracheids: shows that vascular bundle is present which confirms that it is pteridophyte

4. No seeds: confirms that the plant is pteridophyte as vascular bundles with no seed are pteridophyte.

Therefore in the given question, the identified plant is a pteridophyte which in the given option is a fern.

Thus, Option-C is correct.

most community's take hundreds of years to become stable

Answer from: Quest

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.
