Evidence suggests that all animals arose from single-celled ancestors.?
true
How do you thank the ancestors?
If the ancestors you want to thank are living, you can write them a nice letter. If they are not living, you can go to their graves and say thanks, or you can follow whatever your religion suggests is the proper way to communicate with the dead.
How the first human born?
All of the evidence that has been accumulated suggests that there was no "first human". Humans gradually became differentiated from their ancestors.
What are glasshouses?
A glasshouse, as the name suggests, is a structure of mainly glass to allow protected cultivation of plants.
Why do rodents have a longer appendix then humans?
It depends what theory you wish to believe. Darwin suggests that our appendix is a by product of when we were herbivorous primates and it aided our digestion of vegetable matter. If this the case then rodents would have a larger appendix in order to digest their herbivorous diet. The second theory would be that the appendix houses bacteria designed to fit gut infections so, if this is the case then perhaps rodents need greater concentrations of these bacteria due to the conditions with which they live. Not sure how useful this info is after all I'm only a bar tender!
How does comparing the embryos of different organisms support the theory of evolution?
The stages of development of the embryos of certain organisms are extremely similar, a fact that suggests the organisms had common ancestors.
Modern whales have a vestigial perlvis and femur what does this evidence suggest about ancestors of modern whales?
Evidence of a vestigial pelvis and femur suggests about the ancestors of modern whales walked on land and thus, also breathed air. Many other marine life is believed to have been land based before massive climate change and perhaps floods.
Why do people need an appendix?
You don't need appendix. It is a vestigial structure that only might get in your way if it becomes inflamed.However, recent research shows that it creates helpful bacteria.Researchers at Duke University Medical Center say that the function of the frequently discarded appendix, an organ often credited with little importance and often dismissed as having no significant function, does it all;the appendix produces and protects good germs for the gut by "rebooting" the digestive system.However the researchers say sometimes the bacteria die off or are purged from the intestines as in diseases such as cholera or dysentery. According to the researchers, the appendix's job is to "reboot" the digestive system when that happens with the bacteria safely harbored in the appendix.It was once believed that when the human passed gas it caused the appendix to twist and release bacteria ... but that rumor was dissmissedMany doctors believe the appendix is a vestigial organ with no function and is no more than a blind ended tube connected to the cecum, from which it develops embryologically.he cecum is a pouch-like structure of the colon and the appendix is near the junction of the small intestine and the large intestine and has abundant infection-fighting lymphoid cells, which suggests it plays a role in the immune system.The most common diseases of the appendix (in humans) are appendicitis and carcinoid tumors. Appendix cancer accounts for about 1 in 200 of all gastrointestinal malignancies.Appendicitis is a condition where the the appendix becomes inflamed and in almost all cases it is removed either by laparotomy or laparoscopy; left untreated, the appendix will rupture, leading to peritonitis, then shock, and, if continued untreated, death. The appendix is routinely removed without any notable ill effects or side effects and the scientists stress that even though the appendix seems to have a function, people should still have them removed when they are inflamed because since leaving it untreated could be fatal.Dr. Bill Parker, a professor of surgery and one of the scientists responsible for establishing its status as a useful organ, says the function of the appendix seems related to the massive amount of bacteria that populates the human digestive system and where it is located just below the normal one-way flow of food and germs in the large intestine, helps support that theory.The study appears in the online edition of the Journal of Theoretical Biology.
Did you evolve from apes?
No, humans descended from ape-like ancestors. Evidence suggests that the human line split from the first gorillas around four to eight million years ago.
Is bismuth a semiconductor or conductor?
the band structure of bismath suggests a low density of conduction electrones and holes,so it is semi conductor
What evidence suggests that the ancestors of whales once walked on land?
yes the facts book on whales said that 50 million years ago they walked on earth as animals. there fin's as there legs
What does the linguistic relativity hypothesis suggests?
The linguistic relativity hypothesis suggests that language influences the way we think and perceive the world around us. It proposes that the structure and vocabulary of a language can shape the way speakers of that language conceptualize and interpret their experiences.
