What is an example of a variation that could give an individual an advantage for surviving and producing offspring?

It depends on the species and their habitat.
The classic example is the peppered moth in industrial England. There was a light coloured moth that was common in rural towns and cities. As England became industrialised the air became sooty, darkening the bark of trees that the moths spent most of their time on. The lighter moths became more visible to predators and the darker moths in the same species were better able to blend with the bark of trees, hence being able to survive and pass on their colouration to the next generation. So in this case, an example of a variation that could give an individual a better chance of survival and being able to produce offspring would be colour. Since England has been cleaning up its air through stricter laws against pollution, the process has begun to reverse.
In humans i would say being attractive, well off financially, living in a secure environment etc.

Many parasites reproduce asexually suggest why this might be an advantage for the parasitic mode of life?
So that there is a greater chance of the parasites surviving
What is the reproductive advantage that a mammal has over a bird?
Since birds lay eggs, they are more likely to have their eggs eaten. Since mammals keep their fetuses inside of themselves, the baby has more of a chance of surviving.
Why are seeds considered a more effective means of reproduction than spores in a dry environment?
because seeds can store food and nutrients when spores cant, so seeds have a better advantage of surviving in a dry environment.
What are three factors which can lead to an individual organism surviving longer in it's environment?
All organisms need food, water, and shelter in order to live, grow, and reproduce.
Which type plant has the best chance of surviving a variety of environments?
moss
Why do marine mammals spend a lot of energy producing milk for their young?
All mammals expend a significant amount of energy producing milk for their offspring. This is an evolutionary feature unique to mammals and it confers a significant benefit to the offspring - the milk is complete nutrition for the offspring, which gives the offspring better odds of surviving to reproductive age itself.
Darwin noticed that birds that were good at finding scarce food in the winter had a better chance of surviving and producing offspring. What did he call this struggle for existence?
mmmmmm
Darwin noticed that birds that were good at finding scarce food in the winter had a better chance of surviving and producing offspring What did he call this struggle for existence?
natural selection
Darwin noticed that birds were good At finding scarce food in the winter had a better chance of surviving and producing offspring what did he call this struggle fir existence?
Survival of the fittest / natural selection
How many individual Bengal tigers are surviving?
2300 Bengal Tigers
Who leave more surviving offspring elephants or rabbits?
elephants of course as long as they are polish ones from Iraq
Why small numbers of surviving tigers a cause of worry from the point of view of genetics?
The small number of surviving tigers is a cause of worry because of inbreeding. Inbreeding decreases the possibility of viable offspring.
What important adaptation did the surviving giraffes pass on to their offspring?
the long necks and what the parents have but sometimes the giraffes wont be the same as the parents
In Louisiana is the surviving spouse responsible for the child support payments of a deceased individual?
no
How many offspring does the Giant Panda produce and how often?
They produce up to 2 offspring but don't produce to many in a whole life time
How do insecticides force evolution?
Widespread use of insecticides can lead to the evolution of insecticide resistance. In any population of insects there will be genetic variation ie individual insects are not identical; just like humans there are all different. Some individual insects will be more resistant to an insecticide than others. When an insecticide is used the individuals which are resistant will have a better chance of surviving. They will then pass on their resistance genes to their offspring, which will in turn have a better chance of surviving. In this way the resistance genes will spread through the population. This is an example of natural selection in action. See www.evolution.berkeley.edu/
