Answer:
D) The virus has entered the genome of the bacterial cell and is in the lysogenic stage.
Explanation:
Virus have two reproductive cycle lytic and lysogenic cycles. In the lytic cycle, the viral genome is expressed using the host molecular machinery and make capsid proteins. These capsid proteins surround the viral genome and make new phages which lyse the host cell and gets released.
After the release, they enter their genome in other host and that genome first incorporates in the host genome and replicates with the host genome. This cycle is called the lysogenic cycle and in this cycle lysis of cell does take place because no new phages are produced in it.
Independent variable is the one that can be changed to test the prediction.
<u>Explanation:</u>
In order to test the prediction in an experiment, the independent variables are always changed. This is because the independent variable are the one that is always produces different cause and effect in an experiment.
They are not dependent on the outcome of the experiment but can alter the experiment to any extend when they are altered. Hence we can conclude independent variable as right answer.
The number is halved in every half life. So divide 32 by 2 four times and you get your answer.
