Consider the phase diagram for neon: When the pressure is 10-2 atm, at what temperature will neon melt?

What is the smallest bone in the human body?  

Put the following steps in the order of occurrence for intramembranous ossification.   Type the number of the step in the blank.   Example: If you need to go through a door, then you need to turn the door knob and then open the door. So,1 turn the door knob, 2 open the door, 3, walk through the doorway.   [BLANK-1] Osteoblasts deposit spongy bone beginning at center of bone.  [BLANK-2] Connective tissue membranes form at sites of future intramembranous bones.  [BLANK-3] Osteoblasts form layer of compact bone atop the spongy bone.  [BLANK-4] Some cells become osteoblasts. 

Hyaline type found on ends of long bones is

Put the following steps of muscle contraction in order.  Example: If you need to go through a door, then you need to turn the door knob and then open the door. So,1 turn the door knob, 2 open the door, 3, walk through the doorway.   Also, fill in the missing word(s).     __[BLANK-1]__ Myosin cross-bridges detach and reattach to active sites  __[BLANK-2]__ ACh (acetylcholine) is released from neurons – diffuses across _____[BLANK-3]_____ __[BLANK-4]__ Cycle repeats as long as Ca2+ and ATP are present __[BLANK-5]__ Ca2+ binds to troponin on actin filaments, moves tropomyosin out of the way, and exposes active sites on _____[BLANK-6]_____ __[BLANK-7]__ Ca2+ is released from _____[BLANK-8]_____ __[BLANK-9]__ Myosin _____[BLANK-10]_____ attach to actin active sites __[BLANK-11]__ Signal goes from spinal cord to motor neuron – then travels through axons to _____[BLANK-12]_____ terminals  __[BLANK-13]__  ACh binds to receptors on the _____[BLANK-14]_____ __[BLANK-15]__ Contraction – using ATP, myosin cross-bridges attach to actin and pull actin filaments toward center of _____[BLANK-16]_____ __[BLANK-17]__ _____[BLANK-18]_____ (enzyme) from sarcolemma decomposes ACh in the synaptic cleft. Contraction ends, muscles relax. Prepares fiber for next stimulus.

Correctly identify the regions that are lettered.   Be specific.   Please include the letters with your answers.  Example:  If the line from letter S is on a grain of sand, then type S = Grain of Sand  SKIN LAYERS.png 

Identify the objects, lines, discs, bands, and zones in the following figures. If you don’t remember the bands’ letters, at least describe what the structures are for each.   Remember to type the letter with each answer. For example: if Q is antelope, then type Q = antelope.  Sarcomere – to label -.png
