A "variation" is a genetic feature expressed in some physical, physio chemical or behavioral manner by a living organism that is not present in the general population of the species to which that living organism belongs.
If that variation advantages that animal as compared to others of that species then the likelihood is that that animal will breed more successfully, potentially passing on that variation to its offspring.
Slowly variations accumulate and one species changes into a new species - this is called evolution.
Variation provides the ability to adapt to a changing environment. As an environment changes, those members of a given species with advantageous variations will be most likely to survive and produce offspring of their own. In other words, they are more fit.
An adaptation or beneficial mutation.
Mutations are changes in the DNA of an organism. If these mutations help an organism survive in its environment, it would be considered an adaption.
the organism will not survive and will die as a result if it is not quickly restored
Selection or 'Natural selection' means that the organisms that are better adapted to their environment are most likely to stay alive and produce offspring, while Variation means that during natural selection, the organism that is better adapted to the environment starts to form more physical features to help it survive (mutations). For example, Say that there was a white desert. If there were 2 mice, one species is black while the other is white, white would survive, which would be an example of Natural Selection. Variation is if, say, the mice are slow and can still be easy prey, but later on they mutate into becoming faster, that would be variation.
inherited variation
genetic drift
Creation of variation occurs in a species and help in the survival to species as the most suitable or favorable character pass next generation and under unfavorable condition only the most fit organism survive and help in continuation of the species.
Symbiosis help organisms survive by giving an organism's nutrients and energy to another organism.
what variation would help a land survive in long lasting droughts
they have to have things to survive and to adapt to with there organisms
Adaptations
Because on very, very rare occasions the variation may be helpful
That is an adaptation .
a. they help the organism survive in its environnment .
The oxygen in the H2O
reason why organism need trees
Creation of variation occurs in a species and help in the survival to species as the most suitable or favorable character pass next generation and under unfavorable condition only the most fit organism survive and help in continuation of the species.
The two kinds of adaptations an organism can have is a behavioral or a physical adaptation. These both help the organism survive.
