Answer:
The correct answer is option (d)-"immunity to reinfection by any phage".
Explanation:
Lysogeny is one of the two cycles that comprise viral reproduction, at which the bacteriophage genetic information is introduced into the host bacterium's genome. Lysogeny could result in immunity to reinfection by the same phage, however this not happens when the reinfection takes place by any phage. When reinfection occurs by the same phage, the host bacteria acquires immunity resulting from the recognition of their particular DNA sequences. This not happens when reinfection occurs in any phage as they could have different DNA sequences.
.............................Correct.
I think the correct answer from the choices listed above is the last option. It is the hormone oxytocin that is controlled by a positive-feedback mechanism. Oxytocin is normally produced by the paraventricular nucleus of the hypothalamus and released by the posterior pituitary.<span> Hope this answers the question.</span>
Answer:
During <u><em>vegetative propagation</em></u>, a new plant grows from parts of the parent plant.
During<u><em> mitosis</em></u> , a new plant grows from parts of the parent plant.
Explanation:
<em>Asexual reproduction can be described as a type of reproduction in which only one parent is involved and the daughter cells formed are identical to the parent cell.</em>
In vegetative propagation, a vegetative part of the plant such as roots, shoots etc are taken and grown separately. A new plant arises from these parts of the plant.
Mitosis is a type of asexual reproduction in which only a single cell undergoes division to produce two new daughter cells which have the same genetic makeup as the parent cell.
