The nicotine indirectly inhibit the CB1 or also known as the
Cannabinoid receptor type 1, which is the one responsible in obesity and
metabolic syndrome, thus, this would explain the weight gain associated with
people who quit smoke as if this is indirectly inhibited, it produces weight
gain.
 
        
             
        
        
        
Answer:
Option A
Explanation:
The genotypic frequency for tt (q²) = 36% = 36/100 = 0.36
To calculate for the allelic frequency of t which is q, we have to find the square root of q² to do this. Thus 
√q² = √0.36 = 0.6 this q = 0.6
The allelic frequency p for the T allele can then be calculated using this formula p + q = 1
Where q is 0.6 thus p= 1 - 0.6 = 0.4.
This the allelic freq of T is 0.4

The antibiotics target peptides that are not synthesized by the eukaryotic host but are synthesized by the microbes. Example is the targeting of peptides, and their precursors, like lipoteichoic acids, that are significant component of the peptidoglacan cell wall of Gram-positive bacteria.
