so since the third place is fixed, we can count that out organism has8 letters, count out the g since it is fixed oranism has 7 letters first slot=7 choices 2nd slot=6 choices (1 choice from 1 slot) 3rd=1 since only g can be here 4rd=5 5th=4 6th=3 7th=2 8th=1 so the answer is 7 times 6 times 1 times 5 times 4 times 3 times 2 times 1 (last one for g)=5040 ways
