Any species that does not reproduce will go extinct.
By definition, a living thing reproduces. A single individual not reproducing simply means they don't contribute to the next generation's gene pool.
According to a student taking the AP biology exam, he/she lost 10 points by choosing an answer that said viruses are living things and as a result, states that viruses are not living things :http://answers.yahoo.com/question/index?qid=20080926021144AAwdJ2h According to MCAT training materials (MCAT is the test taken to get into med school) Viruses are no considered cells because, among other reasons, they cannot live independently. The MCAT materials say that there is a debate as to whether viruses are living things because of the nature of their life cycle (again - they cannot live independently). Other posts that I found on this topic by searching ask.com say that viruses are not living things because they fail to meet the 7 criteria of living things. Viruses are 20 - 300nm in size and prokaryotes are 1 - 10um. While viruses are smaller, many feel they manufacture rather than reproduce and therefore are not living things. MCAT training materials do not come out and say whether they are living or non-living but refer to them as parasitic, acellular, and incapable of living independently and note that there is debate as to whether they are living things. Once can say truthfully, as another poster noted, viruses fail traditional, established criteria for 'life'. In this instance, I would say the smallest thing that meets the criteria for life is prokaryotes (bacteria). Debatable is whether or not established criteria for life need to be modified in order to accommodate the unique nature of viruses.
In a process called reuptake, they are reabsorbed by sending the neuron and recycled.
variation is the differences in genotypic traits between individuals in a populationnatural selection is any naturally occurring process resulting in differential success of reproduction of individuals depending on the genotypic traits they have expressed as phenotypic traits, the usual means by which this happens is the death of specific individuals prior to being able to reproduce but other events can alter the rate of success of reproduction without the individuals dying (e.g. they reproduce OK themselves but fail to bring those offspring to reproductive age successfully).
You either study harder or fail.
If you fail the physical exam, you may not be able to participate in certain activities or programs that have physical requirements. It is important to work with a healthcare provider to address any areas of concern so that you can improve your physical fitness and try again in the future.
If all members of a species fail to reproduce, the species will die out and can become extinct.
Since plants do not live forever, if they fail to reproduce, they are gone.
No - they would fail to reproduce if they were.
becoe extinct.
They often fail because they don't get the press or are left out of things like debates.
You fail!
Then you fail
Because if they fail to do so, they will die out, and the sole purpose of all life, the main one anyway, is to survive. No living thing wants to be the last of its kind.
They would all fail, they work together.
You fail the test.
why do people die? It happens.
It gets warmer.
