Ecologists are studying the fire coral population in a 280-square-kilometer area on the great barrier reef. fire corals cannot move from one location to another in their environment.

which of the following methods is most appropriate for the ecologists to use to determine the size of the fire coral population?

a. counting all the fire corals in the total area to determine the precise number of individuals in the population

b. determining the size of the fire coral population in a quadrat sample area and using it to estimate the overall population size

c. using a mark and recapture method to estimate the overall population size

d. tagging individual fire corals and returning the following year to count how many are still in the same area

submit

B

Explanation:

it will take too long to count every fire coral in a 280 square km area, B is the most appropiate technique

i got something better   a catchphrase here it is

ahem  

ahem

what the squwock

explanation:

the relative atomic mass of an element is the mass of one atom of that element, relative to 1/12th of the mass of a  1212c atom. to convert to an absolute mass in kg, it is necessary to multiply by  1.661×10−271.661×10−27.

the relative atomic mass is roughly equal to the number of neutrons, plus the number of protons, in the nucleus of the atom.

for elements with more than one stable isotope (different types of nucleus with different numbers of neutrons but the same number of protons), the quoted mass is usually the average mass, weighted by the relative abundance of the different isotopes.
