1) explain, what technology are you using to complete this assignment, how does it work?
2) observe the view outside your window, ask the question about something you have seen (clouds, trees, buildings, moving vehicle etc.)
3) formulate hypothesis about object/fact you observed;
example: when I look at the cloud it changes its shape, because... (predict why)
4) list five (5) facts about your observation, using your five senses (see, smell, taste, touch/feel, hear), list constant or variable facts;
example: I see white clouds, clouds are wet (fog is a cloud), the rain falls from clouds, the air, after rain, smells fresh, some clouds make a
thundering sound, etc.
5) look around your room or your house; can you see a model? describe it.

answer: zinc is the substance which has a volume of 1.38 .

density is defined as the mass of an object per unit volume.

it can be calculated by dividing mass of a substance by its volume i.e.

si unit of density is kg per cubic meter and cgs unit of the same is gram per cubic centimeter.

now from the given data volume can be calculated by the formula .

hence, the volume of aluminium will be = which comes out to be 1.703 .

similarly, volume of zinc, chromium, and nickel will be 1.378 , 0.869 , and 0.356 respectively.

it's a.true. i'm kind of smart.

the answer is: the „power stroke“ step.

muscle contraction can be divided into a few steps:

1. the release of ach (acetylcholine) in the synaptic cleft, binding of ach for its receptor and consequently opening of the ca channels.

2. the release of ca, binding of ca for the troponin

3. troponin shifting the tropomyosin, which was blocking the active site on the actin

4. myosin heads attaching to actin by breaking down atp to adp+ pi

5.   formation of the ‘cross-bridge’ on the active site of the actin filament by myosin head

6. “power stroke” -the cross bridge pulls actin, which slides over the myosin

9.     7. the release of adp completes the cross-bridge movement and atp attaches to myosin, breaking the actin-myosin cross bridge.
