ASEXUAL REPRODUCTION Asexual reproduction is a mode of reproduction by which offspring arise from a single parent‚ and inherit the genes of that parent only; it is reproduction which does not involve meiosis‚ ploidy reduction‚ or fertilization. The offspring will be exact genetic copies of the parent. A more stringent definition is agamogenesis which is reproduction without the fusion of gametes. Asexual reproduction is the primary form of reproduction for single-celled organisms such as the archaea

Evolution of the craniate middle ear The evolution of the auditory structures of the middle ear began with the recycling of the second gill arches in primitive fish (Braxeau and Jeffery 2008). While the first set of gill arches became the upper and lower jaws‚ the upper portion of the second gill arch‚ the hyoid arch‚ became a support structure for the cranium as the hyomandibula (Manley 2010). Examinations of Sarcopterygiian fishes such as Rhipidistians and Rhizodonts describes the role of

Reptiles and mammals differ in nature. For an excellent example of Reptilian fascism‚ watch the excellent NBC miniseries “V” (my rating: 10 out of 10). Not all reptillians are bad‚ there are many good ones as well. The reptilian nature is part of the “sin” nature. Reptiles are hierarchical and territorial in nature. Their genetics are also most compatible with demons and demonic activity. Mammals (like Cats and dogs‚ cows and horses) are more warm-hearted and loving than Reptiles. Men have

This was announced by the WWF (World Wildlife Fund) September 30‚ 2014. Animal populations such as mammals‚ birds‚ reptiles‚ fish‚ and amphibians are about half the size they were 40 years ago. This is a much greater decrease than the scientists originally anticipated. More than 10‚000 animal populations were studied by scientists. These populations consisted of 3‚038 mammal‚ bird‚ reptile‚ amphibians‚ and fish species. These trends in animal populations were then calculated to produce the “Living Planet

propose theories and make assumptions debating whether dinosaurs were warm-blooded or cold-blooded. It was believed that dinosaurs were cold-blooded because dinosaurs were related to reptiles‚ which are cold-blooded. Now many scientists have proposed many reasons why dinosaurs were warm-blooded and not cold-blooded like reptiles. One reason why scientists believe dinosaurs were warm-blooded is because they were active‚ quick‚ and intelligent (Strauss‚ 2014). It is said that dinosaurs displayed characteristics
