Answer:
The correct answer is option A.
Explanation:
Striated muscle tissues are muscle tissue that made up of repeated long functional units known as sarcomeres. The long bands of sarcomeres along with muscle fibers provide it a striated appearance. Striated muscles have more mitochondria in it and also contain cells that are multinucleated, unlike smooth muscles. The major function of these muscles is to generate force and contract. Heart and respiratory organs have such muscle.
Thus, the correct answer is option A.

The answer is shallow, warm, continental seas.
The Ordovician-Silurian extinction happened about 450-430 million years ago. Before the extinction, most multicellular organisms lived in the seas. It was a rich life in shallow, warm, and continental seas. The climate was favorable. Reef-forming corals, as well as the first true vertebrates, some fish, appeared. Trilobites and mollusks were diverse and rich. Green algae were common in the seas.
