Most of the seismic activity on Earth is found on (or near) the boundaries of tectonic plates. Earth's lithosphere is divided into a number of fragments, known as tectonic plates and these plates are in constant motion.
Answer: Option (C)
Explanation: Wegener's theory of Continental drift was replaced by a modern theory called the 'plate tectonic theory'. This theory was able to prove what wegener could not and so was universally accepted.
The new evidences supporting this theory were-
- The coastlines of east America and west Africa are similar in shape suggesting that they might have existed together once upon a time
- Similar fossils were found at different continents such as the glossopteris fauna
- Similar rock sequences found at different places determined by the correlation method
Hence the correct option that satisfies the above question is option (C)
Answer:
C) medium
Explanation:
medium can be solid, semi-solid or liquid
mediums are designed to grow living cells of plants, animals, humans and microbes

Answer:
dry gangrene
Explanation:
Gangrene is not a special form of necrosis, it is a particular form of evolution of a necrosis, which is conditioned by certain germs. These germs act on proteins, especially on hemoglobin, and decomposition products give the blackish color characteristic of gangrene. Pathogenetically there are two different forms of gangrene: ischemic and infectious.
Ischemic gangrene
It occurs in the underlying skin and soft tissues, most often in the lower extremities due to atherosclerotic obstruction. Necrosis is caused by ischemia and saprophytic germs on the skin act secondarily on the necrotic tissue. Depending on the conditions of the compromised tissue, dry or wet ischemic gangrene occurs.
<u>
Dry gangrene</u> In this way the evaporation of water quickly produces a drying of the compromised skin, which transforms into a blackened, dry brown, corrugated sheet. The compromised territory is well demarcated, the germs do not penetrate the depth, there is no intoxication of the organism.
