Agamogenesis is the type of reproduction which does not involve the fusion of gametes. This type of reprod uc tion is the primary form of reproduction for single-celled organisms like archarea, bacteria and protists.Plant and fungi also show asexual reproduction. Asexual reproduction involves only one parent. 2  All the off s pring are identical to the parent. 3  Asexual reproduction does not involve the process of meiosis and fertilization, hence the process does not require a mate for reproduction. 4  This type of reproduction is seen in lower forms of organisms.
Faint/Collapse. Fainting is a temporary loss of consciousness that happens when the brain does not receive enough oxygen. It comes on suddenly, only lasts for a short time and you recover fully within a short time. It is also often called a blackout. The medical term is syncope. It isn't the same thing as a seizure which usually causes jerking.
Common factors that may contribute to societal collapse are economical, environmental, social and cultural, and disruptions in one domain sometimes cascade into others. In some cases a natural disaster (e.g. tsunami, earthquake, massive fire or climate change) may precipitate a collapse.
