Answer:
Ethanol is most likely to be a (B), competitive inhibitor.
Explanation:
The poisoing occurs because of the harmful metabolites produced by the alcohol dehydrogenases, enzymes in charge of breaking down alcohol.
Hence, the most likely strategy of an antidote is to compete for the active site of the enzyme and prevent the methanol convertion to harmful chemicals.
Ethanol does not produce these metabolites and it is preferentially proccessed by the body, so it is a competitive inhibitor, competing for the active site.
Answer:
C) commensalism
Explanation:
Commensalism is an interaction in which one organism benefits without causing any harm to the other. The other organism derives no benefit from the relationship.
The scenario above in which the dwarf mistletoe obtains nutrients from the vascular tissues of trees is a perfect example of such a relationship.
Parasitism is similar to this but the other organism is harmed in the process.
Answer: All birds are warmblooded, or endothermic, animals. Birds are vertebrates because

characteristic they share with mammals. All birds lay hardshelled eggs. Birds have only two legs. Their forelimbs have
become modified into wings for flying. All modern birds evolved
from ancestors that could fly.
