Answers
When a device such as a disk drive or printer signals the CPU to pause its fetch-execute cycle and request attention, it is called an interrupt
In computer science, when a device like a disk drive or printer needs to communicate with the CPU, it can do so by sending an interrupt signal. An interrupt signal is a signal that temporarily stops the CPU's current activities and directs it to attend to the incoming signal. When the CPU receives an interrupt signal, it interrupts its current task, stores its current state, and then switches to another task or process.v This allows devices to communicate with the CPU without requiring the CPU to continuously check for messages. Interrupts can be hardware interrupts, such as when a device signals the CPU for attention, or software interrupts, such as when a program requests a service from the operating system. Interrupts play an essential role in managing the flow of information and resources in a computer system.

def winners(scores): This function takes a single dictionary as its parameter. The dictionary maps candidates to their scores. It should return a list of the candidate(s) with the highest score. The return value should be sorted in ascending order using the sort method on lists. assert winners({"a": 1, "b": 2, "c": 3}) == ["c"]
assert winners({"a": 1, "b": 1, "c": 1}) == ["a", "b", "c"]
def plurality(votes):
Another way to elect a candidate using Ranked Choice Voting is called the "Plurality" method. It assigns one point for being ranked first by a voter. The candidate with the most points wins.
This function should take a list of rankings as its input parameter, and it should return a dictionary. The returned dictionary has candidates as keys, and for each key, the associated value is the total number of first-place rankings for that candidate.
assert plurality(votes1) == {"a": 2, "c": 1}
assert plurality(votes2) == {"a": 2, "b": 1}
assert plurality(votes3) == {"a": 1, "b": 1, "c": 1}

The "Plurality" method is a voting system in which the candidate who receives the most votes in an election is declared the winner. It is commonly used in single-winner elections, such as those for political offices.
The first function, "winners(scores)", takes a dictionary of candidates and their scores as input and returns a list of the candidate(s) with the highest score. To accomplish this, we can first determine the maximum score in the dictionary using the max() function, and then use a list comprehension to find all candidates that have that score. Finally, we can sort the list in ascending order using the sort() method and return it.
Here's an example implementation:
```
def winners(scores):
max_score = max(scores.values())
winners_list = [candidate for candidate, score in scores.items() if score == max_score]
winners_list.sort()
return winners_list
```
For the second function, "plurality(votes)", we are using the "Plurality" method of Ranked Choice Voting to determine the winner. This method assigns one point for being ranked first by a voter, and the candidate with the most points wins. To implement this function, we can loop through each voter's rankings and add one point to the candidate who is ranked first. We can use a dictionary to keep track of each candidate's total number of first-place rankings, and then return this dictionary.
Here's an example implementation:
```
def plurality(votes):
rankings = {}
for vote in votes:
if vote[0] not in rankings:
rankings[vote[0]] = 0
rankings[vote[0]] += 1
return rankings
```
In this implementation, "votes" is a list of lists, where each inner list represents a voter's rankings in order. For example, [["a", "b", "c"], ["b", "a", "c"], ["c", "b", "a"]] represents three voters who ranked candidates "a", "b", and "c" in different orders. The function returns a dictionary where the keys are the candidates and the values are the total number of first-place rankings for each candidate.

TRUE / FALSE. examine your data. does it show an action potential as before? if so, describe the mechanism behind this result.
Answers
False, If the data shows an action potential as before, it could be due to the mechanism of depolarization and repolarization of the membrane potential of the cells.
During an action potential, the membrane potential rapidly depolarizes due to the influx of positively charged ions, such as sodium, into the cell. This depolarization triggers the opening of voltage-gated potassium channels, which repolarize the cell by allowing the efflux of positively charged potassium ions out of the cell.
The underlying cellular mechanisms responsible for generating and propagating action potentials are functioning normally in the context of your specific experiment or study, This rapid depolarization and repolarization result in the characteristic spike-like shape of the action potential.
