Answer:
Feudalism
Explanation:
Feudalism was the leading way of political and economic life in the Medieval era. Monarchs, like kings and queens, maintained control and power by the support of other powerful people called lords. Lords were always men who owned extravagant homes, called manors, and estates in the country
The Digestive System consists of the Alimentary Canal and various other organs whose primary function is to support the Digestive System.
The Alimentary Canal, is a long tube about 10 meters long which starts at the mouth and ends at the anus. This tube consists of multiple sections which each have their own specific functions to perform in the process of digestion. The sections of the Alimentary Canal in the order in which they process food are
the function of the lingual papillae are
The alimentary tract serves primarily to convert food into absorbable particles and to pass them on to the other organs of the body. These events are initiated by mechanical processes (fragmentation, mixing, transport) and the secretion of digestive juices containing enzymes, which act to split proteins, fats and carbohydrates by hydrolysis into constituents small enough to be absorbed (digestion). These end products of digestion, together with water, minerals and vitamins, then pass through the intestinal mucosa, from the lumen of the intestine into the blood and lymph (absorption).
Answer:
Only the extracts from heat-killed cells treated with RNase are unable to transform nonvirulent bacteria into virulent bacteria.
Explanation:
The experiment by Avery, McCarty and MacLeod aimed to identify Griffith's "transforming principle," which is a principle that explains how transformation is a way of recombining, exchanging, or transferring genetic information between organisms or from one organism to another. For this, they used cell that were heat inactivated and purified the transforming principle of these cells.
The purified cells did not give positive results in the tests done by the scientists, but they presented transformants very similar to the DNA. However, Avery suspected that the result should be reinterpreted and that the molecule was not a DNA. This is because RNA degrading enzymes had no effect on the transforming principle and only RNase-treated heat-killed cell extracts are unable to transform non-virulent bacteria into virulent bacteria.
