Four haploid cells are produced by the process of meiosis. The correct answer is D.
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
The neurons conduct impulses over relatively long distance in the body. This is facilitated by their long cytoplasmic extensions
True....................................................................
24.) C - a change in DNA coding can lead to a change in the protein that is produced, which changes structure, and therefore, function.
28.) C - recombinant DNA is artificial, and the other examples can occur naturally
29.) B - if DNA enters and successfully is produced within a plant cell, but is not originally from the plant cell, then the cell has been transformed.
