A lab technician needs to determine whether cells in a test tube are eukaryotic or prokaryotic. The technician has several dyes she could use to stain the cells. Four of the dyes are described in the
table below. Which dye could the technician use to determine whether the cells are prokaryotic or
eukaryotic?
Indicator Dye

A.
Acridine orange
B
Eosin
C.
Safranin
D.
Osmium tetraoxide

it's diluted or concentrated

in a diluted solution, you can add a lot more solute but in concentrated only a little more can be added

answer;

-phase iii

explanation;

phase three begins with the transition of a recovered individual to a phase three team of the appropriate service. this phase usually takes place at a military medical facility in the united states. one of the goals of phase three is family reunification.

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.
