<span>This person is experiencing common physical symptoms of what is called "withdrawals". Opiates, when used illegally, can be highly addictive. This drug targets the central nervous system (the brain, cardiovascular and respiratory systems) and contains opioid receptors that receive opiate drugs. Abusing this drug can disrupt a person's brain chemistry, leading to severe physical withdrawal symptoms as listed in the question.</span>
Distance/Time = 120 Km/2 hours =120/2 Km per hour or for short 60 Km per hour
Explanation:
At position 12 of G protein Ras there is a normal amino acid attached to it called Glycine. Which make Ras protein a highly controlled protein. However, there is another amino acid called aspartate at 12 position which make Ras vulnerable by the formation of weak GTPase enzyme activity and GTP binding. Which prevent Ras from turning off. This the reason why aspartate in oncogenic. Furthermore, weak binding of GTP has influence because its binding can not be hydrolyzed.

Answer:
c) microevolution
Explanation:
Microevolution is the change in allelic frequencies within a population over time.
If natural selection favored birds with beaks and small bodies, that means that the frequency of that phenotype (beak and small body) increased while the frequency of birds with body and large beaks decreased.
In this example we see that in the Darwin's finches population, the allelic frequencies - reflected in the phenotype - changed over time as a consequence of the drought.
