Question

1. A- What is natural selection?
2. True or False: There are enough resources (e.g. food, shelter, mates) in the environment for every single organism to have as much as it wants.
3. True or False: Some organisms within a population may have traits that are not possessed by other organisms within that same population.
4. True or False: Some traits may give an organism an advantage in gathering environmental resources.
5. True or False: Organisms that are more successful at gathering environmental resources will probably die sooner as compared to other organisms.
6. True or False: Organisms that live longer will have an opportunity to have more offspring.
7. True or False: Offspring have traits that are similar to their parents.

Answer 1

NATURAL SELECTION IS THE KEY CONCEPT OF DARWINIAN THEORY OF EVOLUTION. ORGANISMS VARY IN CHARACTERISTICS IN A POPULATION . WHEN RESOURCES ARE LIMITED IN A POPULATION SOME TRAITS WILL HELP SOME OGANISMS TO BETTER ADAPT TO THE CONDITION OF LIMITED RESOURCES. THESE TRAITS ARE INHERITED AND PASSED TO THE NEXT GENERATIONS . THOSE POPULATION  WHICH ARE BETTER ADAPTED IN LIMITED RESOURCES CONDITION WILL PRODUCE MORE OFFSPRINGS. FOR A PEROID OF TIME OVER MANY GENERATIONS THESE POPULATION WILL LEAVE MORE PROGENY THAN THE OTHERS. THIS WILL LEAD TO A CHANGE IN POPULATION CHARACTERISTICS. OVER MANY GENERATIONS THIS WILL SLOWLY LEAD TO THE RISE OF A NEW SPECIES.

FIRST STATEMENT : FALSE

THERE IS NO ENOUGH RESOURCES IN THE ENVIRONMENT FOR EVERY ORGANISMS AS MUCH AS IT WANTS . OR THE RESOURCES ARE NOT UNLIMITED IN AN ENVIRONMENT.

SECOND STATEMENT:TRUE

SOME ORGANISMS MAY HAVE DIFFERENT TRAITS COMPARED TO OTHER ORGANISMS IN THE SAME POPULATION. ORGANISMS HAVING TRAITS WHICH HELP THEM TO ADAPT BETTER WILL PRODUCE MORE PROEGNY THAN THE OTHERS.

THIRD STATEMENT : TRUE

ORGANISMS HAVING SUCH TRAITS WILL PRODUCE MORE PROGENIES.

FOURTH STATEMENT: FALSE

ORGANISMS HAVING FAVOURABLE TRAITS WHICH HELP THEM IN GATHERING ENVIRONMENTAL RESOURCES  WILL PRODUCE MORE PROGENIES.

FIFTH STATEMENT: TRUE

ORGANISMS THAT LIVE LONGER MAY PRODUCE MORE OFFSPRING DURING THE COURSE OF THEIR LIFESPAN.

SIXTH STATEMENT: FALSE

OFFSPRINGS MAY HAVE DIFFERENT TRAITS COMPARED TO THEIR PARENTS . THIS IS DUE TO SUDDEN HERITABLE CHANGES KNOWN AS MUTATION
