Answer:
adaptations are compromises
Explanation:
The pleiotropic gene involved in sickle-cell anemia is an example of heterozygous advantage. This means that the heterozygous genotype is favourale over other two genotypes (recessive homozygous and dominant homozygous). Eventhough it has harmful effect (sickle cell disease carrier) heterozygous genotype enables resistance to infection (malaria) and that is why this genotype is still favourable by natural selection. This phenomenon is evidence of compromise between harmful ad benefit.
So here is the most obvious thing here… tolerance is a physical effect of repeated use of a drug, a great example would be a alcohol. Always the Tolerance does not always equal a type of addiction. Withdrawal: Symptoms a person experiences when not using a substance, due to the body reacting to no longer having the substance. Now back to the alcohol… alcohol is a very commonly used on types of drugs, for an example like regular rubbing a alcohol, drinking and more. This type can really make somebody addicted to the type of substance that is in it. Hope this helps!
