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.
Answer: program adherence, weight is an indirect measure
Explanation:
Program adherence is also called exercise compliance or adherence and it is used in describing how a patient is sticking to his or her exercise program and following the recommendations by their personal trainer or health professional.
With regards to the question, if the behavior of interest is program adherence, weight is an indirect measure. This is because weight in this case is used as a means to determine the calories burned and other vital components to be known. Weight is an indirect measure because we are really not interested in knowing the weight, it's just a means to an end.
