If coliforms are found in a water sample, the imvic tests will determine whether the coliforms are of fecal origin and not from plants or soil. what imvic results would indicate the presence of fecal coliforms

If the IMVic test detects the presence of E. coli it means that the water is contaminated with faecal coliforms.

Explanation:

The IMVic test is a test that can be used to discover contaminants in water. The water may be contaminated by fecal coliforms or substances from plants and soil. These substances are associated with the presence of some bacteria, which is why the IMCic test is so efficient.

The IMVic test is able to detect the presence of Klebsiella, Enterobacter and Escherichia coli bacteria. If after the application of the test, the presence of E. coli in the water is detected, it means that the water is contaminated with faecal coliforms. If the presence of Klebsiella or Enterobacter is detected it means that the water is contaminated with substances of plant origin or soil particles.

there are 35 white marbles

step-by-step explanation:

y- yellow marbles

4y + 5 = 45

subtract 5 from both sides

4y = 40

divide for from both sides

y = 10

plug in 10 to get 40 yellow marbles then subtract by 5 to get 35 marbles

thus there are only 10 yellow marbles
