A patient was being treated for an infection using an antibiotic. At seven day intervals a swab was taken from the mouth and cultured in a fresh agar plate.what questions that pls write q and a
Day 1 plate: 1 grey:9 white
Day 8 plate: 4 grey:3 white
Day 15 plate: 7 grey:1 white
White = species 1 Grey = species 2
(A) Species 1 was a food source for Species 2 allowing more of Species 2 to grow.
(B) Species 1 and Species 2 are both fungi, but Species 1 is killed by the antibiotic while Species 2 uses the antibiotic as food.
(C) As the number of Species 2 increased, they changed the chemical conditions of the agar plate stopping the growth of Species 1.
(D) There is normally a balance between the number of each species but the removal of Species 1 by the antibiotic allowed more of Species 2 to grow.
