Why is it that some species can reproduce faster than a pharmacy can fill a prescription?

Because some of them are called rabbits. You know, like Catholics.\n\nWord.

Humans are not the only ones. Primates do and yes dogs and cats do as well. Other sexually reproducing species go through oestrous cycle. Very similar to menstrual cycle, except it isn't always seasonal. Some rodents for example ovulate every 4-5 days; while others are induced ovulators meaning they only ovulate after sex. Both types have cyclical endocrine changes that lead to ovarian changes and ovulation. Interesting tidbit though is that humans are the rare ones...other species only have sex to procreate...humans have sex whether they can have kids or not (while they are pregnant or elderly, for example).

It is E\n\nThe reason: \na) Reproductive variations lead to the "better producer" making more offspring and thus leading to more chances for their offspring to reproduce.  For this one, think of gorillas...the dominant Male (silverback) will mate with the females so it is his offspring who carry the genetics into the next generation, and the other males in the group dont pass on their genes. \n\nb) There has to be some offspring that simply don't survive...this is the whole "don't interfere and let nature take its course" thing.  This means that after the "unhealthy" individuals die, the rest (on average) will be better suited to their environment.  Think of it like this... a  human family has three babies but one of them dies; the one that died may have had a defect that shouldn't have been passed on.  Since the parents had two other babies, they have replaced themselves in the population so there will not be a net loss of population when they eventually die. \n\nc) There has to be variations in the genetics of the offspring.  This is due to the fact that for us to become better suited to our environment, there has to be a change in our genetics to produce that change.  If we were exactly like our parents, no changes could occur.\n\nd) Inheritance is hugely important.  Think about it like this: If a beneficial change develops (such as opposable thumbs), what good would it be if it couldnt be passed on to the next generation?  There must be a mechanism to pass the benefit on.  \n\ne) Even though there have been many catastrophic events that have allowed for natural selection, it is not required.  A large eruption may cause the animals who can eat more diverse variety of plants to do better than ones that can't but they may be able to out-compete the other animals anyway.

Science has found that while not impossible for the two species to have sex, they were too different to reproduce- it was impossible for a egg of one and a sperm of another to come together and become an embryo.

You need to talk to your doctor or pharmacist about this,as some meds are time release and some are not. Also,some pills are not made to be cut in half,because the medication is not evenly distributed throughout the pill.\nDon't try to figure this one out here or by yourself,please!

I asked that question, and there is no known mechanism. There is however a mechanism that keeps different species from being able to interbreed.

The "Red Queen " theory of why there is sexual reproduction, states that organisms sexually reproduce to vary the immune response to ever changing bacterial and viral evolution, weather natural or artificial selection. You see the asexual organism having great reproductive numbers, this makes vulnerable populations to parasitical attack, hence they clone rapidly. There is also the genetic recombination component that other answers to your question brought up.

atoms are moving faster in hot water, and are hitting surface of the pill more often thus knocking molecules away from the pill more often, thus disolving faster

The only thing that comes to mind is population growth.  The more people (or whatever organisms) there are, the faster their population grows.

Think about the advantages of each reproductive mode. Asexual is easy, and fast, and the offspring are clones.\nSexual is more complex and the offspring get a combination of both parents' genome, as well as new variations that could have arisen during gamete production. Natural selection, which will influence these organisms heavily under changing conditions, acts upon these random variations.

It honestly is hormones,  some people produce more than others.  Also, certain conditions, like ADD produce more sweat thus potentially more order.

i havent heard that example, but its possible. that would possibly fall into the category of microevolution...like when birds beaks get bigger or smaller to crack different nuts. its still a bird, with slightly different attributes. that would be an example of artificial rather than natural selection though, since it would be people choosing what they think is attractive, rather than nature killing off people who were less well equipped to deal with the environment.

rapid reproduction time can allow for fast adaptation/high mutation rates\nno problems with internal transport of nutrients, diffusion/osmosis sufficient\nnot problem with breathing, no need for a lot of specialized organs. All reducing the possibilities for a lot of diseases (less complicated, less can go wrong). Cancer is not going to be a problem, ever. \nreproduction by simple cell division viable option (no complicated sex life  -does s/he really love me - confusing the critter)\nrequire comparatively less energy, not just because of small size, but also because they don't need to expend energy on coordinating and maintaining all those extra organ systems - like we expend a lot of energy just to keep our brain going, whether we use it or not. \ndon't need much space, the earth can support more bacteria than humans...\nthere are obviously also disadvantages, otherwise we all would be unicellular.

Its possible but some times its not good to do so by medicines etc.

some can, depends on the species

any living thing by its interaction with the environment goes on accumulating toxins that ultimately result in death. Usually the animals with a high metabolic rate are the quicker to die, but they breed fast and can evolve faster, as there are many generations in a small time.\n\nall cells are genetically programmed to die. this time is different for different species

I believe the ecoli replicates much much faster than cultured human pancreatic cells.
