In the middle of the picture inside some of the cells if you look closely you can see white worm like things, these are the brood or larvae. On the left it is hard to tell on this picture but some of the larva have been capped which means they are growing through the last stage of growth and will emerge as bees.
You can see packed pollen in some of the cells and on the outer cells it looks like they are glistening, this is nectar. As you notice there are many bees with their heads stuck inside the cells. They are sucking up nectar. Bees do this when you smoke the hive, they think it is on fire and are eating as much as possible getting ready to flee. This is why smoke calms them down, really it makes them more concerned with self preservation than with what someone is doing in the hive.
You can see how some pollen is bright red and orange!
The bees have started to build out this frame but have a way to go.
