Aleonysh [2.5K]

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.

The right answer is: Leptin .

Leptin is a hormone closely linked to the regulation of energy consumption and expenditure: appetite, metabolism, and hunger.

A hormone is a protein with a messenger function. This means that once released into the bloodstream, she goes to another part of the body to transmit a message to specific receptors.

Leptin is manufactured in white adipocytes (adipose tissue) where triglycerides (fats) are stored and acts on the hypothalamus.

SashulF [63]

Answer:

The correct answer is option C.

Explanation:

The Chondrichthyes is a class that comprises the cartilaginous fishes such as batoids, ratfish, sharks and others, The Chondrichthyes and the Osteichthyes also known as bony fish were distinguished in early classification but it was not clear at that time when bony skeletons appeared in the vertebrates.

Traces of bone tissues that are found in fossil and living Chondrichthyes are suggested that these cartilaginous fishes derived after the origin of the bony skeleton in vertebrates.

Thus, the correct answer is option C.
