Explain how the method of mark and recapture works to determine population size

      N = MC/R

Where; N is the population size estimate,

            M is the total number of organisms captured and marked during                                 the first time,

             C is the total number captured the second time, and

             R is number of marked organisms recaptured during the second time.

there are no statements provided but here is why:

sulfur belongs to group 16 because it can be found in nature whether it is in a free or combined state.

hope this

the correct option is c.

isotopes refers to different forms of the same element with the same atomic number but different mass number as a result of difference in their neutron numbers. isotopes have different relative atomic mass but share the same chemical properties.
