bool isbnCheck(string isbn) {
if (isbn.length() != 13) return false;
int sum = 0;
for (int i = 0; i < 13; i++) {
if (!isdigit(isbn[i])) return false;
int digit = isbn[i] - '0';
sum += (i % 2 == 0) ? digit : digit * 3;
}
return (sum % 10 == 0);
}
Explanation:
first checks if the length of the input string isbn is 13, and returns false if it is not. Then, a variable sum is initialized to keep track of the sum of the weighted digits, and a for loop is used to iterate through the digits in the ISBN number. For each digit, the isdigit function is used to check if the character is a digit, and the function returns false if it is not. The digit is then converted to an integer by subtracting the ASCII value of the character '0', and is added to the sum with a weight of 1 or 3, depending on the position of the digit. Finally, the function returns true if sum % 10 is equal to 0, which indicates a valid ISBN-13 number, and false otherwise.paraphrasing clarifies the message for both sender and receiver. paraphrasing clarifies the message for both sender and receiver. true false

According to the passage, which of the following best describes how a bottom-up cascade would reduce population size throughout the community?
Read Passage
A
The removal of the piscivorous fish population would cause an increase in the size of the smaller fish population. The smaller fish would then eat more of the zooplankton, leading to an increase in the size of the phytoplankton community.
B
The removal of the zooplankton population would allow phytoplankton to flourish. However, the smaller fish would no longer have a source of food, causing their population to decline rapidly. As the smaller fish died off, the piscivorous fish would also lose their food source, so their population size would also decline.
C
A small increase in the piscivorous fish population would lead to a slight decrease of the smaller fish. With less smaller fish present, the zooplankton population would increase slightly, leading to a slight decrease in the phytoplankton population.
D
The removal of the smaller fish would cause an increase in the size of the zooplankton population. With an excess of zooplankton, the phytoplankton population would decline rapidly. Additionally, without the smaller fish, the piscivorous fish would not have any source of food, and their population would also decline rapidly.
It can be inferred that the option that the correct option is
"The removal of the zooplankton population would allow phytoplankton to flourish. However, the smaller fish would no longer have a source of food, causing their population to decline rapidly. As the smaller fish died off, the piscivorous fish would also lose their food source, so their population size would also decline." (Option B)
What is the rationale for the above response?The loss of the zooplankton population would cause the smaller fish population to dwindle since they would no longer have a food supply. Because of a scarcity of food, the piscivorous fish population would diminish as the smaller fish population declined.
This would result in a decline in total fish numbers. Meanwhile, removing zooplankton would initially allow phytoplankton to grow, but over time, the excess phytoplankton would deplete available nutrients, resulting in a fall in the phytoplankton population.
