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>
Answer:
Explanation:
Density, the weight of an object divided by its volume, is a property of all matter, including solids, liquids and gases. The value of an object's density depends on what it's made of as well as its temperature; for example, lead weights are denser than feathers, and cold air is denser than hot air.
In order to produce an effective immune response within the body, the person must be injected with a dosage of a virus or bacteria, and for it to be allowed to grow in the person, which replicates just enough to stimulate a response from the immune system.
Bacteria have been the very first organisms to live on earth in the waters of the first oceans. At first, there were only anaerobic heterotrophic bacteria.
Answer:
Genotype - AaMm
Phenotype - Heterozygous purple stem and fruit with two locules
Explanation:
Given
Trait 1 - Recessive allele for green color stem is represented by a
and dominant allele for purple color stem is represented by A
Trait 2 - Production of two locules in the tomato fruit is a dominant trait and is represented by "M" and production of multiple locules in the tomato fruit is a recessive trait and is represented by "m"
F1 cross is carried between tomato plant with purple stem and fruit with two locules (AAMM) and a tomato plant that have fruit with multiple locules and a green stem (aamm)
The following offspring will be produced
AM AM AM AM
am AaMm AaMm AaMm AaMm
am AaMm AaMm AaMm AaMm
am AaMm AaMm AaMm AaMm
am AaMm AaMm AaMm AaMm
Genotype - AaMm
Phenotype - Heterozygous purple stem and fruit with two locules
