The lifetime of an intracellular signaling molecule must be short for the cell to be able to cause a change in the concentration

ivann1987 [24]

Answer:

Statement B is false.

Explanation:

PKA and PKG is both have binding domains to attach with nucleoside monophosphate and help in modulating these enzymes that explains that PKA is more related to the PKG than PKC at the level of amino acid.

At the level of polypeptide chain level PKG has single polypeptide chain whereas in PKA modulatory domains are located on different poly peptide chain. Both are activated by the nucluoside triphosphate, more precisely PKA by cAMP and PKG is by cGMP respectively, whereas PKC is activated by DAG or Ca or both depending on the isofom.

Thus, the correct answer is - option B.

Microscopic plants called algae grow inside the top layer of sea ice in the Antarctic if enough sunlight reaches that layer of i

MrRa [10]

Answer:

The correct answer is: (A).

Explanation:

In the question, it is mentioned that the algae can grow under the conditions of "enough sunlight" and "enough nutrients".
Sunlight reaches the algae, by first falling on the surface made up of ice and snow and then refracting from there into the top layer of the ice where the algae grows.
However, the capability of both snow and ice to reflect sunlight is far more than that of refracting sunlight.
Therefore, the amount of light received by the algae is similar in absence or presence of the layer of snow on the top layer of ice.
However, on deposition of snow on the layer of the ice, the weight of the ice increases and it sinks below into sea water.
This allows more nutrient rich sea water to percolate into the ice and reach the algae.
The algae receive more nutrients from the sea water and hence is capable undergoing better metabolism and growth.
Hence, more algae are produced under such a situation.
