In transduction, DNA is accidentally moved from one bacterium to another by a virus. In conjugation, DNA is transferred between bacteria through a tube between cells. Transposable elements are chunks of DNA that "jump" from one place to another.
According to the most widely used species definition, the biological species concept, a species is a group of organisms that can potentially interbreed, or mate, with one another to produce viable, fertile offspring.
- Hybridization is known to happen between what are generally accepted to be different species — sometimes this leads to new species, other times som...
- Dogs are currently undergoing speciation. However, because they have only recently have split into many breeds, it will take much more time for the...
- They are constantly influenced by variable factors of their environment which may cause more changes in their karyotype. Moreover, most plant speci...
- No, because the offspring is able to reproduce which means that the two parents are of the same species. Plus, just because organisms live in diffe...
- There may not be a barrier — I did a brief look online, but didn't find anything relevant and don't know whether anyone has tried making hybrids of...
- Organisms belong to the same species if they can interbreed to produce fertile offspring. Species are separated by prezygotic and postzygotic barri...
- All domestic dogs evolved from the grey wolf species. Australian dogs were brought to Australia by humans. African dogs were brought to Africa by h...
- Speciation in plants may happen faster just like genetical engineering is much easier to conduct in plants. Plants are polyploid but can reproduce...
- Allopatric? But they eventually can swim apart and change depths?
- The biggest factor is with the rate of creating offspring. The shorter the time between generations the faster that speciation can occur.
What is biology? In simple terms, biology is the study of life. This is a very broad definition because the scope of biology is vast. Biologists may study anything from the microscopic or submicroscopic view of a cell to ecosystems and the whole living planet (Figure 1.2).
Which definition or definitions is useful for identifying asexual and sexual species? Why might different definitions work in different environments, for different types of organisms, or at different junctures of individuals’ lives?
Jul 13, 2024 · What is impressive is not just the numbers but also the incredible heterogeneity in size, shape, and way of life —from lowly bacteria, measuring less than a thousandth of a millimetre in diameter, to stately sequoias, rising 100 metres (300 feet) above the ground and weighing several thousand tons; from bacteria living in hot springs at temperat...

Mar 28, 2019 · Speciation is a process within evolution that leads to the formation of new, distinct species that are reproductively isolated from one another.
Evolution is a process that results in changes in the genetic material of a population over time. Evolution reflects the adaptations of organisms to their changing...
