A meiotic division produces 2 daughter cells.
Answer:
(C) DNA
Explanation:
This experiment shows that when bacteriophage infects bacteria, it only inserts its DNA (radioactive phosphorus is incorporated only in nucleic acid, while radioactive sulfur is incorporated only in proteins). Proteins with incorporated sulfur are located within the capsid of bacteriophage, which stays outside the bacterial cell.
there is a redundancy in the genetic code / a silent mutation has occured
Answer:
b. Pollen tubes did not enter all of the ovules in such pods
Explanation:
Quite sometimes, ovules fail to mature seeds because most of their flowers do not receive enough pollen to fertilize all of their ovules and are eventually aborted, thereby resulting in some ovules becoming mature seeds and others do not get matured.
