Answer:
Thin and Thick filament.
Explanation:
The actin and myosin are the important proteins of the muscles. These proteins shows striations of the skeletal and cardiac muscle, when observed under the microscope.
Actin protein is the major constituent of the thin filament. Thin filament is 7 nm in diameter and made of globular proteins. Myosin protein is the major constituent of the thin filament. This filament is 15 nm in diameter.
Thus, the actin comprise of thick filament and myosin comprise of thin filament.
Bal stands for Bronchoalveolar lavage. Bal is a process in which a bronchoscope is passed through the mouth and then into the lungs. Fluid is squirted into a part of he lung and collected for examination. Lung diseases can be found from the process of bal.

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:
Different types of intercellular junctions, including plasmodesmata, tight junctions, gap junctions, and desmosomes. Plasmodesmata (singular form: plasmodesma) are intercellular organelles found only in plant and algal cells. Tight junctions are located within our body's epithelia. Epithelia is the plural of epithelium. Epithelium is a word that refers to the covering of the body's internal and external surfaces. This includes organs (such as skin), blood vessels, and cavities. Gap junctions are found in many places throughout the body. This includes epithelia, which are the coverings of body surfaces, as well as nerves, cardiac (heart) muscle, and smooth muscle (such as that of the intestines). Desmosomes are prominently found in cardiac muscle
