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.

Im pretty sure it is 50% i am terribly sorry if its wrong but i like positive its that
Explanation:
Answer: True
Explanation:
Kidneys are defined as a pair of bean-shaped organ present in the abdominal cavity of mammals, reptiles, and birds responsible for excretion of urine.
Renin is a peptide hormone which is secreted by the kidneys from granular cells that are present in the juxtaglomerular apparatus. The secretion of renin stimulation is based on decrease in sodium chloride in the juxtaglomerular apparatus by the macula densa, fall in arterial blood pressure in the arterial vessels by baroreceptors and sympathetic nervous system activity is through beta 1 adrenergic receptors.
Hence, the given statement is true.
