Select reasons why members of phyla acrasiomycota, myxomycota, and oomycota not classified in the kingdom fungi. at some point in their life cycle, these species are motile. when present, the cell walls are composed of cellulose. in their early stages, these species can perform photosynthesis. these species can reproduce sexually.

The correct answer is -

statement 1 and statement 2.

Explanation:

Acrasiomycota and myxomycota are fungus-like molds which are coming under the protist kingdom.  however some consider acrasiomycota as an individual kingdom. Oomycota is also fungus-like molds that are saprotrophs or parasites. Their cell wall is not made up of the chitin as fungi but only cellulose.

All three phyla are not considered as fungi and not include in the kingdom fungi due to their motile body at some point in the life cycle. The cell wall of these phyla is composed of the cellulose instead of the chitin.

Thus, the correct answer is -  

statement 1 and statement 2.

Electrical stimulation of the cell is depolarization, and electrical relaxation of cells is repolarization.

Explanation:

The electrical activity of the cell depends on the charges distributed on each side of its membrane, which depends on the presence of ions on each side, extracellular sodium and intracellular potassium.

A cell, like the neuron, at rest has a tendency to be negatively charged in its cytoplasm, while the extracellular space has a positive charge.

Depolarization of a cell occurs by opening the sodium channels, allowing this ion to enter the cell, resulting in a difference in transmembrane potential.  It is electrical stimulation of the cell.If the potential difference is maintained and reaches the umbral level, it produces an action potential, which in cells such as the neuron produces an electrical stimulus and in the muscle cell a contraction. Repolarization means the opening of potassium channels, the exit of this ion to the extracellular space and the return of the cell to rest.
