Answer:

Option a) higher the average sea levels.

Explanation: Carbondioxide is also known as greenhouse gas. When carbondioxide concentration is higher in the atmosphere, it prevents the reflected sunlight from going into the atmosphere which increases the temperature of the surrounding air. This phenomenon is called global warming. This increase in temperature starts melting of ice which are present on mountains and thus, increases sea level.

When an organism changes due to mutations that are selected in their environment, they are considered a new species when:.

Vladimir [108]

Answer:

There is some debate about the definition of a species, especially across fields. However, what it likely being discussed here is the biological species concept which states that:

An organism is considered a new species when there is reproductive isolation from the population that they originated from. In other words, for two organisms to be the same species they must be able to reproduce to create viable (able to survive) and fertile (able to reproduce) offspring.

Reproductive isolation can occur by different means, classified as being prezygotic or postzygotic isolation. These include things like mechanical, behavioral, temporal, ecological, and geographical isolation for prezygotic isolation. And things like hybrid infertility and hybrid inviability for postzygotic isolation. These are not relevant to the question but they give you an idea of what you could look up if you wanted more information.

In a macrotube (macrobroth) dilution susceptibility test, 1.0 ml of Mueller Hinton (MH) broth is pipetted into tubes 2 through 1

ExtremeBDS [4]

Answer:

In a macrotube (macrobroth) dilution susceptibility test,

1.0 ml of Mueller Hinton (MH) broth is pipetted into tubes 2 through 10, tube 11, and tube 13.

Two milliliters of MH broth is pipetted into tube 12;

1.0 ml of 200 micrograms/ml of ampicillin is added to tubes 1, 2, and 13.

A twofold serial dilution is performed in 1.0 ml amounts in tubes 2 through 10.

The standardized inoculum is diluted 1:200 and 1.0 ml is added to tubes 1 though 11.

The tubes are incubated for 20 hours at 350 C.

After this time, the tubes are examined for visual growth.

Tubes 6 through 7 are visibly turbid, while tubes 1 through 5 show no signs of growth. Tubes 1 through 5 are plated on blood agar, incubated overnight at 350C, and read for growth. Plates 1 through 4 show no growth while several colonies are observed on plate 5.

The MIC is:

The tubes 1 through 5.

Explanation:

The MIC is the tube which gets the lowest anti-biotic concentration showing no visible growth, and as tubes 6 through 7 are visible turbid.
