Aid Another bonus to roll?

Sorry if this is a double posting, but I couldn't find the answer to my question in an older thread:

While looking over the d20pfsrd site rules for Aid Another, I've managed to confuse myself on what exactly you roll/add for this type of check.

The rules state to make an attack roll... so do I add my BAB and an Ability Modifier? If so, which?

Thanks for any clarity you can give me!

Aiding another works as though you were performing the action yourself, except the DC/AC is always 10.

When you aid another in combat, you make an attack roll with a melee weapon you're wielding, so you apply all the bonuses you usually apply when making an attack with that weapon.

When you aid another in a skill check, you make a skill check roll and use your normal bonuses to that skill.

Aid another can also be used against spell effects, although as far as I know there's been no clarification on how that works. My best guess is that you would roll the same save as an ally who is about to roll a save to break the effect.

Thanks! I really appreciate the clarification :)

Aid another is used against spell effects when the spell tells you that you can. For example, you can use the aid another action to wake someone from a sleep spell. There are other cases as well.
