Answer:

Option B

Explanation:

ALL options are as follows -

a. teosinte and maize can produce fertile hybrids.

b. teosinte and maize have similar chromosomes.

c. Both Teosinte and maize have naked, soft kernel.

d. Teosinte and maize can produce fertile hybrids

Solution

Beadle started working on maize genetics since 1962 after joining graduate school at Cornell University.  

During his research he found that the chromosomes of teosinte and maize possess higher similarity and also show signs of intercross ability of the two species and hence confirmed that wild teosinte is an ancestor of domesticated maize.  

He later concluded that there are only 4 to 5 genes that make these two species different from each other rest all is similar.  

Option B is correct

Methanol poisoning occurs when the body converts a large amount of methanol to harmful chemicals that attack the optic nerves, l
Triss [41]

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.
