NEET BIOLOGY

Detailed explanation-1: -If an organism has a mutation that increases its chances of survival, it’s more likely to reproduce and have offspring with that mutation. Organisms that fail to survive, obviously, will not pass on their traits. Whether or not an organism survives to reproduce depends on their surrounding environment.

Detailed explanation-2: -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-3: -Because resources are limited, more organisms are born than can survive: some individuals will be more successful at finding food, mating or avoiding predators and will have a better chance to thrive, reproduce, and pass on, their DNA. Small variations can influence whether or not an individual lives and reproduces.

Detailed explanation-4: -Organisms that are more adapted to their environment are more likely to survive and pass on the genes that aided their success. This process causes species to change and diverge over time. Natural selection is one of the ways to account for the millions of species that have lived on Earth.

Detailed explanation-5: -Individuals with adaptive traits-traits that give them some advantage-are more likely to survive and reproduce. These individuals then pass the adaptive traits on to their offspring.
