women's college rules

[BamaRef]

I took my youngest daughter to a women's college game. I have some question reguarding rules and mechanics.

Is there a 10 second count in the backcourt?

Is there a 5 second count in the frontcourt?

If the ball is strong side, next to the baseline, does the trail or lead signal the three point try?

I watched the officials signal illegal contact two different ways. The first used an open palm with a hatchet chop motion, the second used a closed fist with a hitting motion to signal. Which way is correct?

I also noticed that the trail always chopped the clock in. Is that conference mechanic or is that practiced nation wide?

Finally, I noticed that while shooting free throws, the women standing along the lane lines stand on block higher up from the baseline than the men. Can they enter when the ball is released, or must they wait until it gets to the rim?

Thanks for your help, I'm sure I'll have more questions later.
