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.
The plane or planes of the section would be Oblique, coronal, transverse.
What is anatomy ?
The area of biology known as anatomy is dedicated to the study of the composition and organization of living things. The structural organization of living things is the focus of the natural science field of anatomy. It is an old science with roots in the Paleolithic era. Given that these are the processes via which anatomy is produced, whether over short- and long-term timescales, comparative anatomy, evolutionary biology, and phylogeny are intrinsically linked to anatomy. A common pairing of related disciplines is anatomy and physiology, which examine the structure and operation of organisms and their components, respectively. One of the fundamental basic disciplines used in medicine is human anatomy.
Therefore you would require Oblique, coronal, transverse planes for the internal anatomy of both lungs at the same time,

Answer: Prostrate gland
Explanation:
Prostrate gland is the part of male reproductive system. It is present at the base of the bladder. It produce the fluid which comes as seminal vesicles through ejaculatory ducts finally to the urethra. The urethra is a tube which runs through prostrate gland. In case of cancer, the imflammation of prostrate takes place. As a result of this urethra tube becomes narrow and restricts the flow of urine.
Answer:
In general Asian music, but most particularly Chinese, has called the attention of westerners because of the sensed differences with the music that we are accostumed to listen to in the west. This is why, when we go into a restaurant that is Asian, and we hear the tunes being played, we become aware of how different they sound from what we are accustomed to.
There are several reasons for why this happens, but the most important of all is the difference in the scale system that Chinese music composers use, versus ours. While in the west we use a 7-note scale system, most Asian music, and most particularly Chinese music, use what is known as the pentatonic, or 5-note scale.
Also, Chinese music is usually played with solo instruments, or very small ensembles, not how it is done in the west, and the emphasis tends to be on certain types of wind instruments such as zheng, and also on cymbals and gongs, which give this type of music a very peculiar characteristic.
These are only a few of the reasons why Chinese music may sound so different to what western people are used to.
