LIFE SCIENCE

Detailed explanation-1: -In natural selection, genetic mutations that are beneficial to an individual’s survival are passed on through reproduction. This results in a new generation of organisms that are more likely to survive to reproduce.

Detailed explanation-2: -An adaptation is any heritable trait that helps an organism, such as a plant or animal, survive and reproduce in its environment.

Detailed explanation-3: -Offspring with favorable variations are more likely to survive and reproduce. Gradually, individuals with favorable variations make up more of the population.

Detailed explanation-4: -Organisms produce more offspring than actually survive. Organisms can die from many causes: disease, starvation, and being eaten, among other things. The environment can’t support every organism that is born. Many die before they are able to reproduce.

Detailed explanation-5: -All organisms produce more offspring so that more can survive to adulthood and reproduce. This means that many of those offspring will die without reproducing. Only the survivors are able to reproduce pass their traits on to their offspring.
