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:
types 4,8,10
Explanation:
1.
Fibril-forming collagens (I, II, III, V, XI, XXIV, XXVII);
2.
Fibril-associated collagens with interrupted triple helices (FACITs) (IX, XII, XIV, XVI, XIX, XX, XXI, XXII). The FACITs do not form fibrils by themselves but they are associated with the surface of collagen fibrils.
3.
Network-forming collagens (IV, VIII, X) form a pattern in which four molecules assemble via their amino-terminal 7S domain to form tetramers while two molecules assemble via their carboxy-terminal NC1 domain to form NC1 dimers
4.
Membrane collagens (XIII, XVII, XXIII, XXV)

Answer:
Anterior Compartment syndrome is related to big tibialis anterior muscle that from by swelling and bleeding. It can be acute or chronic. Muscle become bigger if more time passes.
Explanation:
It can be caused by trauma. Based on symptoms such as; pain, it can be diagnose. Its only treatment is surgery. By muscle compartment cutting, it allow muscle to swell, blood pressure decrease.
