Ans.
Tuberculosis (TB) is a bacterial infection that affects mainly respiratory tract and can be transmitted from one to another person through contaminated air. The causative agent of tuberculosis, <em>Mycobacterium tuberculosis</em> has developed resistance against many antibiotics, such as rifampin and isoniazid, which is known as tuberculosis drug resistance.
If a person infected with TB shows drug resistance against some TB drugs, 'doctors should give other TB drugs to that person, even if these drugs show less effect than common drugs'. This is because these drugs can prevent or kill the bacterium more effectively than the common drugs for which, bacterium is resistance.

Answer: Phosphorous
Explanation:
Phosphorous can be used to label Nucleic acid. Nucleic acids can be modified or labelled using tags .
Some common materials or substances that can be used to label nucleic acids are flurophore, enzymes, radioactive phosphorous, biotin et cetera.
The nucleic acid of virus is labelled using phosphorous. When this virus will infect the host cell then nucleic acids will be seen separately.
Answer:
It allows it to disolve easily
Explanation:
It is a chemical change
We know that Hardy-Weinberg conditions include the following equations:
where 
And where p = dominant, and q = recessive; this means that 
is equal to the homozygous dominant, 
is the heterozygous, and 
is the homozygous recessive .
So we have 100 total cats, with 4 having the recessive white coat color. That means we have a ratio of 
or 0.04. Let that equal our 
value.
So when we solve for q, we get:
Now that we have our q value, we can use the other equation to find p:
So then we can solve for our heterozygous population:
This is the ratio of the population. So we then multiply this number by 100 to get the number of cats that are heterozygous:
So now we know that there are 32 heterozygous cats in the population.
