He was an American microbiologist and biophysicist. His main focus was upon genetic codification.
in 1977, Carl Woese and George E. Fox discovered a kind of microbial life which they called the “archaebacteria”. It composed "a third kingdom" of life different from bacteria, plants and animals. His three-domain system, divided life into 23 main divisions, incorporated within three domains: Bacteria, Archaea, and Eucarya.
Earlier scientists used to divide organisms in two major groups, the prokaryotes which consisted of bacteria and the eukaryotes which consisted of all the other higher organisms. Carl Woese divided organisms in three groups: Bacteria, Archaea and Eukaryotes. He concluded that Archaea are more similar to eukaryotes than to bacteria. Previously Archaea were thought to inhabit only hostile extreme places but now they have also been discovered in other less hostile environment.
Archaea are similar to bacteria when it comes to morphology. But the process of translation and transcription is significantly different from bacteria and resembles eukaryotes more. Their cell membrane have unique ether linked lipids for more stability and they have some unique metabolic pathways like methanogenesis.
The deer and tick have a parasitism relationship as only the tick benefits from the relationship and the deer is being harmed. If Both were benefiting it would differ.
Aerobic respiration has higher energy production as glucose is fully broken down in restoring cells while anaerobic respiration is doesn't fully break down glucose and is used once the heart and lungs can't keep up with the capacity of oxygen needed for aerobic this usually happens during sprints in athletics
DNA is a dynamic and adaptable molecule. As such, the nucleotide sequences found within it are subject to change as the result of a phenomenon called mutation. Depending on how a particular mutation modifies an organism's genetic makeup, it can prove harmless, helpful, or even hurtful.
