Aspecies of mud snail was studied for five years. during this time, scientists observed the season in which they mated, the number of offspring they produced, and the results of such stressors as drought, famine, and lack of mates. which question were the scientists most likely studying? a. what is the food source most often chosen by the mud snail?
b. are mud snails able to reproduce both asexually and sexually?
c. are mud snails more likely to choose mates with colorful shells?
d. do mud snails prefer to live in water or near a water source?

"Are mud snails able to reproduce both asexually and sexually?" is the one question among the choices given that the scientists were most likely studying. The correct option among all the options that are given in the question is the second option or option "B". I hope the answer helps you.

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.
