1. Have you saved your circuit to your profile with the correct title and set it to "public?"

Yes, I have.

2. Take a look at the counter circuit pictured below. Is it synchronous or asynchronous? How do you know? Give at least two reasons.

It is synchronous. For one, the clock inputs are all connected to the same "clock". Also the way that the output of the former flip-flop are connected to an "and" gate which in turn need the input of the former gates in order for the next flip-flop to "flip".

3. Unlike the circuit we built in the video, the circuit above is set to count DOWN. How would you be able to tell this just by looking at the circuit? What's the difference?

The -Q instead of the Q out is connected to the input of the next flip-flip causing it to count down.

4. Explain in your own words: How does the difference you pointed out in question 3 make the counter count DOWN? Hint: take a look at the binary count table (pictured below).

It causes it to count down because when the first gate "ticks" it turns into a zero but since it's a zero and the "and" gate is now showing a "0", it "pulls" the "1" from the next gate and so on causing it to "count down".
