Doing as the pioneers did—walking for miles, eating little, sacrificing worldly comforts (and cell phones)—may be a daunting task, but it can come with great rewards as you draw closer to your pioneer predecessors and the Lord. Follow these guidelines to make the experience as positive as possible.

Embryo cell junction. Coloured scanning electron micrograph (SEM) of the junction between 2 blastomere cells in an 8-cell embryo, 3 days old. … The surface of each cell is covered in microvilli (red), tiny projections. Microvilli increase the cell surface area & here also function as bridges communicating between the cells. At the 8-cell stage embryo cells are loosely joined allowing the cells 2B separated 4 in vitro studies. On day 4 blastomere cells fuse together tightly (compaction)…

Bees initially make circular cells and use their body heat to turn the wax into a viscous liquid. Then the surface tension at the 3-point junctions pulls the wax into a hexagonal shape. wow! so now I know.....WD

David Goodsell's Neuromuscular synapse. The acetylcholine-laden vesicles are carrying and releasing the neurotransmitter (ACh) from the neuron (upper 1/3) into the synaptic cleft (the middle pink section filled with laminin, collagen, perlecan and flower-like acetylcholinesterase). The muscle cell is the bottom 1/3.
