The correct statement is that the whale carcass dissociates down over time as different communities of organisms will feed on the whale for months.
An ecological succession includes an array of modifications in the biotic community with regard to the variations in the non-living elements like availability of sunlight, water, and other elements along with time, unless and until stability is attained by the ecosystem.
When a whale carcass sinks to the floor of the ocean it develops an environment suitable for succession to take place as an ocean floor possess low biological activity prior of the sinking of the carcass into the ocean floor, and as the carcass sinks it achieves high biological activity. Various scavenger organisms and a range of decomposers can feed on the carcass. This will lead to an upsurge in the number of these feeding organisms. Hence, it can be stated that the whale has started the process of succession in the previously less active ocean floor.
B and C
When particles get colder and lose energy, they begin to move less and less. Gas particles move the most, with solid particles moving the least. So, it makes sense that if the substance loses energy and gets colder, it will also transform from gaseous state to liquid state since the particles are also moving slower as a result of it losing energy.

Answer:redox reactions; organic
Explanation:
Answer:
Option (2).
Explanation:
The cell potential or membrane potential may be defined as the difference in the electric potential between inside and outside of the cell. The membrane potential of the cell changes during the propagation of action potential.
The resting membrane potential is -70mV. The influx of sodium ions causes the depolarization of the cell membrane. The cell potential changes from -70mV to + 30mV. The membrane potential becomes more positive during the depolarization phase.
Thus, the correct answer is option (2).
