disa [49]

Taking it before exercise may stop the symptoms before they come.  Albuterol is a bronchodilator that relaxes muscles in the airways and increases air flow to the lungs.  Albuterol inhalation is used to treat or prevent bronchospasm in people with reversible obstructive airway disease. It is also used to prevent exercise-induced bronchospasm.

A population of 100 rats was analyzed for their genotype at the isocitrate dehydrogenase locus. There are two alleles (R and S)
goldfiish [28.3K]

Answer:

Yes, this population lies in Hardy-Weinberg equilibrium as it follows both the principles of Hardy-Weinberg.

Explanation:

Here ,

f(A)= p=0.575

f(B)= q=0.425

As per the first principle of hardy Weinberg, the sum of all the alleles at the locus must be equal to 1.

Thus,

p+q=1\\0.575+0.425 = 1\\1=1\\

Also, as per the second equation of Hardy Weinberg's equation-

p^{2} + q^{2} +2pq =1

(0.575)^2+2(0.575)(0.425)+(0.425)^2=1\\0.3306+ 0.48875+ 0.180625=1\\1=1\\

Hence, this population lies in Hardy-Weinberg equilibrium as it follows both the principles of Hardy-Weinberg

It is the Archaea. The Archaea constitute an area and kingdom of single-celled microorganisms. These microorganisms are prokaryotes, which means they have no cell core or some other layer bound organelles in their cells. 
Archaea are microorganisms that characterize the breaking points of life on Earth. They were initially found and depicted in extraordinary conditions, for example, aqueous vents and earthly hot springs. They were additionally found in a different scope of profoundly saline, acidic, and anaerobic conditions.
