Given question is incomplete. Complete question has been attached.
Answer:
C. Excessive potassium has diffused out causing hyperpolarization.
Explanation:
The nerve action potential can be divided into following stages:
- Stimulus is detected by the cell in resting stage.
- Sodium channels in the membrane open from where influx of sodium ions occur which is called depolarization
- After a while, sodium channels close and potassium channels open from where efflux of potassium ions occur which is called repolarization.
- The membrane potential further lowers due to continous efflux of potassium ions which is called hyperpolarization.
- After a while potassium channels close and membrane returns to its resting stage.
In the given figure, stage 4 depicts hyperpolarization because the membrane potential has dropped to the lowest point below -70mV. Hence, option C is correct.
Mitosis, a procedure of cell duplication, or multiplication, amid which one cell offers ascend to two hereditarily indistinguishable girl cells. Carefully connected, the term mitosis is utilized to depict the duplication and dissemination of chromosomes, the structures that convey the hereditary data.
A concise treatment of mitosis pursues. For a full treatment, see development: In cells; cell: Mitosis and cytokinesis.
Preceding the beginning of mitosis, the chromosomes have imitated and the proteins that will frame the mitotic axle have been incorporated. Mitosis starts at prophase with the thickening and curling of the chromosomes. The nucleolus, an adjusted structure, shrivels and vanishes. The finish of prophase is set apart by the start of the association of a gathering of strands to frame a shaft and the breaking down of the atomic layer.
The chromosomes, every one of which is a twofold structure comprising of copy chromatids, line up along the midline of the cell at metaphase. In anaphase every chromatid pair isolates into two indistinguishable chromosomes that are destroyed to inverse closures of the cell by the shaft strands. Amid telophase, the chromosomes start to decondense, the axle separates, and the atomic films and nucleoli re-structure. The cytoplasm of the mother cell partitions to frame two girl cells, each containing indistinguishable number and sort of chromosomes from the mother cell. The stage, or stage, after the consummation of mitosis is called interphase.
P.S. You're a mean person. You ought to pursue different people groups bearing and don't simply answers something for focuses. Fortunately, I revealed you and your answers got delted and afterward erased the 50 points that you escaped your focuses. Try not to do that or else no one's going to like you. Bye....

I hope this helped you!
Well If the Salmon die from lack of food from polution or something, and other animals benafit from the nutrience they carry. the rest of the ecosystem might parish, i hope that helped im not sure what was wanted
