vovangra [49]

Bone canaliculi are microscopic canals between the lacunae of ossified bone. The radiating processes of the osteocytes (called filopodia) project into these canals. These cytoplasmic processes are joined together by gap junctions. ... In cartilage, the lacunae and hence, the chondrocytes, are isolated from each other.

The pKa for the side chain of histidine is 6.0. What is the ratio of the deprotonated imidazole side chain to the protonated sid
Solnce55 [7]

Answer:

When the pKa is 6.0, we can determine the fraction of protonated H is by:

pH = pKa + log [A]/[HA]

Where

A = Deprotonated imidazole side

HA = Protonated side

Given, pH = 5.0

5 = 6 + log [A]/[HA]

log [A]/[HA] = -1 (take antilog of both side)

[A]/[HA] = 0.1

The ratio of the deprotonated imidazole side chain to the protonated side chain at pH 5.0 = 0.1

Given, pH = 7.5

7.5 = 6 + log [A]/[HA]

log [A]/[HA] = 1.5 (take antilog of both sides)

[A]/[HA] = 31.62

The ratio of the deprotonated imidazole side chain to the protonated side chain at pH 5.0 = 31.62

Iorek lives near the North Pole. The snow in his backyard adds water to the atmosphere through _____. transpiration evaporation
barxatty [35]
<span>Sublimation. It's the same effect as evaporation but sublimation means it goes from a solid state (snow) to a gas state. This phenomenon can be seen in your freezer, when ice cubes evaporate the moving particles on the surface fly off to the environment just like in liquids.</span>

What are cell cycle regulators
Artyom0805 [142]

Answer:

Cell cycle regulators are the cell cycle only when they are tight bound to CDKS.

Explanation:

To be fully active, the CDK/Cyclin complex must also be phosphorylated in specific locations. Like all kinases, CDKS are enzymes (kinases) that phosphorylate other proteins. Phosphorylation activates the protein by changing its shape.
