Answer:The correlated trait exercise shows that when two characters are correlated, the optimal values and selection strengths rise and fall together.

Explanation: Correlation refers to statistical (linear) relationship between two random variables. When traits are correlated, change in one is associated with change in the other.

Correlation coefficient (c.c.) measures strength of association between two variables in the same individual or experiment. It can range from -1 to +1. C.c. can be positive, negative or weak.

1. A positive c.c. means that an increase in one variable is associated with an increase in the other variable.

2. A negative c.c. means that an increase in one variable is associated with a decrease in the other.

3. A c.c. near zero indicates a weak relationship between the variables.

Correlation can be represented by scatter plot as shown in the attached image.

Answer:

Following are the code to this question:

#include <iostream>//defining header file

#include <vector>//defining header file

using namespace std;

void PrintVectors(vector<int> numsList)//defining a method PrintVectors that accept an array

{

int j;//defining integer variable

for (j = 0; j < numsList.size(); ++j)//defining for loop for print array value

{

cout << numsList.at(j) << " ";//print array

}

cout << endl;

}

int main()//defining main method

{

vector<int> numsList;//defining array numsList

numsList.push_back(101);//use push_back method to insert value in array

numsList.push_back(200);//use push_back method to insert value in array

numsList.push_back(103);//use push_back method to insert value in array

numsList.erase(numsList.begin()+1);//use erase method to remove value from array

numsList.insert(numsList.begin(), 100);//use insert method to add value in array

numsList.insert(numsList.begin()+2, 102);//use insert method to add value in array

PrintVectors(numsList);//use PrintVectors method print array value

return 0;

}

Output:

100 101 102 103

Explanation:

In the above-given code, inside the main method an integer array "numList" is defined, that use insert method to insert value and use the erase method to remove value from the array and at the last "PrintVectors" method is called that accepts a "numList" in its parameter. In the "PrintVectors" method, a for loop is declared, that prints the array values.

Predict how the sympathetic reflexes controlling blood vessels would respond to a sudden decrease in blood pressure

Goryan [66]

<span>Baroreceptors are special receptors that detect changes in your blood pressure. Important baroreceptors are found in the aorta and the carotid sinus. If the blood pressure within the aorta or carotid sinus increases, the walls of the arteries stretch and stimulate increased activity within the baroreceptors.</span>
