¿por que la toria de lamarck sobre el alargamiento del cuello de las jirafas por el esfuerzo continuado no pasara a sus descendi

Paha777 [63]

Respuesta: Los caracteres adquiridos no se transmiten genéticamente porque no modifican el ADN de los organismos

Explicación:

Jean-Baptiste Lamarck al igual que Charles Darwin, propuso una teoría sobre la evolución que explicaba cambios en los organismos a través del tiempo. La teoría de Lamarck se enfocaba en condiciones en el ambiente que propiciaban cambios en los organismos. Un ejemplo de esto son las jirafas, que de acurdo a Lamarck tenían cuellos largos debido al esfuerzo continuado para comer hojas de árboles altos. Esto significa que la característica de cuello largo era adquirido por las jirafas durante su vida y según Lamarck se transmitiría a sus descendientes.

Sin embargo, se ha comprobado que los caracteres adquiridos no modifican el ADN de los organismos, por ejemplo las cirugías estéticas no cambian el ADN de una persona y por esta razón no son transmitidos a sus descendientes. Por el contrario, en las poblaciones de organismos ciertas características prevalencen en el tiempo debido a la selección natural. Esto significa que el cuello de las jirafas es el resultado que el cuello largo sea una característica beneficiosa que ha prevalecido debido a la selección natural y no de características adquiridas que son transmitidas a descendientes.

Write a program that takes a point (x,y) from theuser and find where does the point lies. The pointcan

agasfer [191]

Answer:

C++ Program .

#include<bits/stdc++.h>

using namespace std;

int main()

{

int x,y;//declaring two variables x and y.

string s;//declaring string s..

cout<<"enter x and y"<<endl;

cin>>x>>y;//taking input of x and y..

if(x>=0 &&y>=0) //condition for 1st quadrant..

cout<<"the point lies in 1st Quadrant"<<endl;

else if(x<=0 &&y>=0)//condition for 2nd quadrant..

cout<<"the point lies in 2nd Quadrant"<<endl;

else if(x>=0 &&y<=0)//condition for 3rd quadrant..

cout<<"the point lies in 3rd Quadrant"<<endl;

else //else it is in 4th quadrant..

cout<<"the point lies in 4th Quadrant"<<endl;

cout<<"enter n to terminate the program"<<endl;

while(cin>>s)//if the user has not entered n the program will not terminate..

{

if(s=="n")

{

cout<<"the program is terminated"<<endl;

exit(0);

}

cout<<"you have not entered n please enter n to terminate the program<<endl;

}

Explanation:

The above written program is for telling the point lies in which quadrant.I am first declaring two variables x and y.Then after that taking input of x and y after that checking in which quadrant the point lies.

Taking input of the string s declared earlier for program termination the program will keep running until the user enters n.

Answer:

For loop Version:

#include <stdio.h>

int main()

{

int number, sum = 0;

printf("Enter a positive integer: ");

scanf("%d", &number);

for (int i = 0; i <= number; i++) {

if(number == 0)

break;

sum += number;

printf("Enter a positive integer: ");

scanf("%d", &number);

}

printf("Sum is: %d", sum);

return 0;

}

- - - - -

While Loop Version:

#include <stdio.h>

int main()

{

int number, sum = 0, i = 0;

printf("Enter a positive integer: ");

scanf("%d", &number);

while (number != 0) {

sum += number;

printf("Enter a positive integer: ");

scanf("%d", &number);

}

printf("Sum is: %d", sum);

return 0;

}

Do-while Loop Version:

#include <stdio.h>

int main()

{

int number, sum = 0, i = 0;

do {

printf("Enter a positive integer: ");

scanf("%d", &number);

sum += number;

} while (number != 0);

printf("Sum is: %d", sum);

return 0;

}

Explanation:

- Initialize the variables

- Ask the user for the numbers until the user enters 0

- Calculate and print the sum
