What was the rationale of using `^32P` and `^35S` by Hershey and Chase? Instead, if we use radiolabelled C and N, will the results be any different?

Answer the following questions based on Hershey and Chase's experiments. What was the need for using a blender an later a centrifuge during their experiments?

You are repeating the Hershey-Chase experiment and are provided with two istotopes ^32p and ^15N (in place of ^35S in the original experiment). How does you expect your results to be different?

What happens when we subtract an interger from another integer ? Can we say that the difference is also an integer ? Observe the following table and complete it . "Statement" " " "Observation" (i) 7-9=-2 " " "Result is an interger" (ii) 17-(-21)=....... " " ............... (iii) (-8)-(-14)=6 " " "Result is an integer" . (iv) (-21)-(-10)=...... " " .............. (v) 32 -(-17)=..... " " ............ (vi) (-18)-(-18)=.... " "............... (vii) (-29)-0=...... " " ............... What do you observe ? Is there any pair of integer whose difference is not an integer ? Can we say integers are close under subtraction ?

A parallel plate capacitor, each with plate area A and separation d is charged to a potential difference V. The battery used to charge it is then disconnected. A dielectric slab if thickness d and dielectric constant K is now placed between the plates. what change, if any will take place in electric field intensity between the plates.
