This works for organisms that reproduce sexually, such as animals, but the definition of a species becomes more complicated when we think of organisms that reproduce asexually, such as bacteria. In this case, modern science such as genetic and protein sequences can be used to assess how ...

Fertilization is necessary for all organisms that reproduce sexually and there are two mechanisms by which fertilization can take place. These includeexternal fertilizationin which eggs are fertilized outside of the body andinternal fertilizationin which eggs are fertilized within the female reproductive t...

The anal canal itself is rich in nerve endings, but the rectum, which sits just past the canal, shares a thin wall with the vaginal canal, she notes. This means that the G-spot, the internal apex of the clitoris, can be reached indirectly — through the backdoor, if you will — thr...

All fungi belonging to the phylumGlomeromycotareproduce asexually. These organisms form asymbiotic relationshipwith plants where the hyphae of the fungus interact with plant root cells. The relationships allow the plant and fungus to received more nutrients. ...
Living organisms need to reproduce to sustain their species. Some species reproduce sexually and combine their DNA to produce a new organism. Sexual reproduction requires both an egg and sperm that combine to create a new organism that possesses a combination of genes from both parents. Organisms ...
