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.

A weight loss plan that may successfully lead to weight loss but does not consider the nutritional requirements and other health issues is a <u>fad diet.</u>
Plans marketed as the finest and quickest way to lose weight are called fad diets. However, several of these diets call for skipping meals that include the nutrients your body needs to stay healthy. Some diets blame specific hormones for weight gain, implying that eating can alter the body's chemistry. These diets are frequently poorly or incorrectly researched.
Every fad diet has one thing in common: it suggests a short-term cure to a problem that, for many people, is a lifetime issue. When a diet is discontinued, the weight lost usually comes back rapidly. Fad diets aren't sustainable for the rest of your life since they don't emphasize lifestyle improvement, which is important to keep the weight off.
