Answer:
The correct answer will be option-C
Explanation:
The CsCl gradient centrifugation in Meselson Stahl experiments is done to separate the bands of the DNA containing isotopes on the basis of difference in the density.
In the experiment, bacterial cultures were grown in the medium of 15N and 14N but if we repeat the experiment with P32 and P31 instead of 15N and 14N and centrifugation is performed then the banding pattern will be the same as of the previous experiment as the method of the replication is same that is semi-conservative.
Thus, Option-C is the correct answer.
A theory that states that only the organism with traits that are useful to the environment survive. For example, short-neck giraffes would’ve died out years ago as they can’t reach the trees nor eat grass on the ground.
Answer:
Throat infection turns into Tuberculosis.
Explanation:
A small infection can be changed into a big disease if it can't be controlled through medication and treatment. For example, at first coughing occurs due to throat infection but increase its intensity leads to more damaged to the throat which leads to the Tuberculosis disease. So this means that if the duration of a small disease increases, it turns into a big problem.
