They all evolved from LUCA (the Last Universal Common Ancestor).
Or, in better terms, they are all living organisms.
Answer:
Observe the graphic for the answer
Explanation:
1.- The first channel from left to right is the pump that exports protons, as you can observe, there are plenty of protons in the outside part, so the cell need to balance the quantity, that is the reason to be of a pump.
2.- The channel in the middle is the responsible for moving calcium, the same as the protons, from the outside part to the inside of the cell.
3.- The lactose carrier, that is the last channel, since the lactose is a carbohydrate that is quite big, needs a protein as a carrier to move it from the outside part to the inside, actually, some carriers can modify it shape as we can observe in the drawing to get inside some substances.
Hope this info is useful.
Answer:
The correct option is : a. diameter
Explanation:
The Kirby–Bauer test or the disk diffusion test, is a method to determine the antibiotic sensitivity of the given bacteria. This test involves the use of antibiotic discs to determine the effect of antibiotics on the bacteria.
In this test, the wafers having antibiotics and the bacteria are placed on the agar plate and incubated. If the antibiotics present stops the growth of the bacteria, there will be an area around wafer with no bacterial growth, such an area is known as the zone of inhibition.
<u>The </u><u>diameter of this zone of inhibition</u><u> is measured to determine the </u><u>antibiotic sensitivity of the given bacteria</u><u>.</u>
