What are the differences between activating and deactivating groups in electrophillic aromatic substitution?

Activating groups donate electron density either through inductive effects or resonance. They are usually ortho and para directed, which means the subsequent groups added will either be in the 2 or 4 position relative to the functional group.
It is easy to determine if a functional group is activating if it electronegative molecules are single bonded.
Examples: alkyl groups (-CH3), alkoxyl (-OCH3), amino (-NH2), thio (-SH),
The exception to the trend that activating groups = ortho/para are halides. Halides are deactivating groups because of strong electronegativity, but they are also ortho and para.
Molecules that are double bonded like -NO2, HSO4, and halides are deactivating. They are meta directed, adding molecules at the 3 position.

Activating and deactivating group of Ortho para and meta director groups Explain?
You can either deactivate or activate the group of Ortho para and Meta director groups depending with your preference.
Why do none of the substrates given as choices for this experiment include any with meta-directing group?
Because none of the substrates are deactivating. Both of the substrates, p-xylene and ethylbenzene, have slightly activating groups which direct ortho or para.
Can activating and deactivating the service usage on a cellphone take the cell phone off flight mode?
No. That's settings. If you really can't figure out how to change it back restore factory setting. If you have an android, go to shut it off, then when you have the screen up, it gives and option to take flight mode off. Search your settings high and low, otherwise.
What is register globals in php?
Globals (global variables) are variables which are valid globally, which means they are available not only in a single function but "generally" throughout the script. register_globals is a switch which is defined in php.ini activating/deactivating this behavior. Since register_globals and the concept of globals is said to be removed for PHP6, it is advised to keep globals off and do not use global variables at all.
How would you expect the genes in the cells of your finger to compare with the genes in the cells of your liver?
Whether the DNA is from your finger, your liver, or your brain, the genes are all there. Depending on where the cell differentiated, different genes are activated while others are dormant. The genes in liver are also present in fingers, they just aren't activated. As of right now, scientists have no way of activating or deactivating a gene.
