What are Problems in the biological species concept?
There are two main problems that can be identified in the biological species concept. This concept emphiasizes interfertility between organisms. However, reproductive barriers between sexual reproducing species are not always effective. Sometimes, individuals of different species interbreed and produce offspring call hybrids. Also this concept fails to describe species that are predominantly asexual in their reproduction, including all bacteria as well as some protists, fungi, plants, and even a few animals.
Sexually reproducing species show greater variation than asexually reproducing species due to?
the shuffling of genetic material through sexual reproduction, which introduces new combinations of genes and increases genetic diversity in offspring. In contrast, asexual reproduction produces identical offspring through mitosis, resulting in less genetic variation within the population.
For organisms to be classified as the same species they must be able to breed with each other and produce?
viable offspring. This means that members of the same species can interbreed and their offspring must be capable of surviving and reproducing as well. This reproductive isolation distinguishes one species from another, ensuring that genetic differences accumulate over time. However, there are exceptions to this definition, especially in cases of hybridization and asexual reproduction.
Think critically for a species what are some advantages of reproducing asexually of reproducing sexually of having the ability to do either?
Asexual reproduction offers advantages such as rapid population growth and the ability to colonize environments quickly, as it requires only one parent and less energy to find mates. In contrast, sexual reproduction promotes genetic diversity, which enhances adaptability to changing environments and increases resilience against diseases. The ability to reproduce either way, known as facultative reproduction, provides a species with flexibility; it can switch to asexual reproduction in stable environments for efficiency or opt for sexual reproduction in fluctuating conditions to foster genetic variety. This dual strategy can optimize survival and evolutionary success.
What are the differences between species that require sexual reproduction and species that require asexual reproduction?
ones a hore and the others not
Which concept applies to asexually reproducing species?
some bacteria...
Sexually-reproducing species have an advantage over asexually-reproducing species in there ability to?
Sexually-reproducing species are able to adapt more easily than asexual-reproduciing species
Are parrots asexual?
No. All birds are sexual creatures, reproducing by the male and female of the species mating.
What type of organism is species a difficult term to define?
It's not so much the organism or a type of organism that is difficult to define as a species but rather the differences in the theories regarding the definition of the word 'species'. For example the Biological species concept and phylogenetic species concept can be at odds when looking at convergent/parallel evolution.
Why does a sexually-reproducing species have an advantage over asexually-reproducing species?
Sexually-reproducing species have an advantage over asexually-reproducing species in their ability to use two different sex cells.

What are the Names of asexual animals?
Some examples of asexual animals are flatworms, starfish, and certain species of insects like aphids. These animals are capable of reproducing without the need for a mate through processes such as fragmentation, budding, or parthenogenesis.

the shuffling of genetic material through sexual reproduction, which introduces new combinations of genes and increases genetic diversity in offspring. In contrast, asexual reproduction produces identical offspring through mitosis, resulting in less genetic variation within the population.
Dinobryon is a species of protozoa that reproduces asexual. How can this asexual reproduction be harmful to the species?
They have less genetic diversity in their population.
What are two limitations of the biological species concept?
Two limitations of the biological species concept are that it cannot be applied to asexual organisms or fossils, and it may be difficult to determine reproductive isolation in some cases where different species can still interbreed and produce viable offspring.
Why is it particularly difficult for the systematist to classify asexually reproducing organisms as a species?
Asexually reproducing organisms do not interbreed
Sexually-reproducing species have an advantage over asexually-reproducing species in their ability to?
Sexually-reproducing species have an advantage over asexually-reproducing species in their ability to produce genetically diverse offspring, which can help them adapt to changing environments and resist diseases more effectively. Additionally, sexual reproduction can help remove harmful mutations from the gene pool through processes like genetic recombination.
