NEET BIOLOGY

Detailed explanation-1: -The idea of natural selection is that traits that can be passed down allow organisms to adapt to the environment better than other organisms of the same species. This enables better survival and reproduction compared with other members of the species, leading to evolution.

Detailed explanation-2: -Adaptations are beneficial to organisms because they allow organisms to be better suited to live in a particular environment. When a genetic mutation occurs that produces a feature or skill that is helpful to the organism in their environment, they will live more successfully and will likely survive to reproduce.

Detailed explanation-3: -The characteristics of an organism that help it to survive in a given environment are called adaptations. Adaptations are traits that an organism inherits from its parents.

Detailed explanation-4: -Examples include the long necks of giraffes for feeding in the tops of trees, the streamlined bodies of aquatic fish and mammals, the light bones of flying birds and mammals, and the long daggerlike canine teeth of carnivores.

Detailed explanation-5: -Adaptations are slow and incremental, and the result of successful adaptation is always beneficial to an organism. Snakes lost their legs to fit into underground spaces, mice grew large ears to hear predators at night, and giraffes developed long necks to reach the leaves on tall trees and bend down to drink water.
