Human Anatomy & Physiology (Human Body Systems) · Catch-up day 2 of 19

Wed, Jan 27, 2027

Two things today. First, here is everything that was due since your last catch-up day, so you can see what you still owe and turn it in. Then the rest of the period is Research Track time.

Step 1 · Am I caught up?

Check off what you have actually turned in. Anything left unchecked is what today is for: open that day and use its Turn it in card.

Period

Your code, not your name. This tells your teacher who needs time, not who to mark down.

Were you out for any of these? You get two school days for every day you were absent, so this deadline moves with you.

Step 2 · Research Track
Research Track session 5: The master switch: how a cell chooses its fate

Two cells carry the same instructions. Why does one build hard tissue while the other builds flexible support?

Open session 5

This one is the next in the track for this course. The site does not track where you are in the track, so if you have already done it, open the track and take the next one you have not.

Research Track work is enrichment, the same track your lessons link to. It does not replace anything on the checklist above.
